Gradle mixed versions warning

Gradle mixed versions warning - android

My app uses API 19, I put a MapView inside of one of my layouts and added the google maps implementation. Now I'm getting a warning from gradle that I'm mixing versions.
Here is the warning:
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0-rc02, 26.1.0. Examples include com.android.support:animated-vector-drawable:28.0.0-rc02 and com.android.support:support-media-compat:26.1.0 more... (Ctrl+F1)
Here are my gradle dependencies:
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0-rc02'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.android.volley:volley:1.1.1'
implementation 'com.google.android.gms:play-services-maps:15.0.1'
The warning is showing for 'com.android.support:appcompat-v7:28.0.0-rc02'.
I'm unsure where to find the correct version to use for play-services-maps or how to resolve this issue properly. I do not want to downgrade my min version from 19.

Add this at the end of your build.gradle (:app)
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
details.useVersion '26.1.0'
}
}
}

the suggestion reads:
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes).
this means, that you'd have to exclude 26.1.0 and provide 28.0.0-rc02 instead:
implementation "com.android.support:support-media-compat:28.0.0-rc02"
implementation "com.android.support:support-v4:28.0.0-rc02"
implementation ("com.google.android.gms:play-services-maps:15.0.1") {
exclude group: "com.google.android.gms", module: "support-media-compat"
exclude group: "com.android.support", module: "support-v4"
}
there might be further versions clashing, while fixing them works the same.

1.Go to project/.idea/libraries folder on your file system and see which libraries are different.
2.You will have to manually include these libraries with the same version in your build.gradle file.
3.Then, sync your project
In Your Case:-
implementation 'com.android.support:animated-vector-drawable:28.0.0-rc02'
You need to add Dependency :-
implementation 'com.android.support:support-media-compat:28.0.0-rc02'

//put this things in build.gradle(Project) file
allprojects {
repositories {
maven {
url "https://maven.google.com"
}
jcenter()
google()
}
}

You need to fallow the below steps.
1- project/.idea/libraries
here you will see which library is different.
You can correct the different one according to your all libraries.
Then, sync your project.

Just add this lins
implementation 'com.android.support:customtabs:28.0.0-rc02'
implementation 'com.android.support:support-media-compat:28.0.0-rc02'
implementation 'com.android.support:support-v4:28.0.0-rc02'

Confronted to the same issue, I solved it by doing the following:
Checked the sdk version for my project, in the build.gradle file, to know the version and change the libraries accordingly
Then I had to override the libraries and change the versions that are inline with the sdk
The image attached shows the libraries I had to override:
com.android.support:animated-vector-drawable changed to 28.0.0
com.android.support:support-media-compat changed to 28.0.0
com.android.support:support-v4 changed to 28.0.0
What I understood is that the android support, drawable and compat libraries were predefined with the 26.1.0 version and my sdk version and target was 28 so I had to change that.
My gradle runs smoothly, and have not yet experienced any problem.

After updating to android studio 2.3 I got this error message.
I know it's just a hint as the app run normally but it's really strange.
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and com.android.support:mediarouter-v7:24.0.0
my gradle:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])

You can solve this with one of the following solutions:
Update:
As of Android studio 3.0, it becomes much easier as it now shows a more helpful hint, so we only need to follow this hint.
for example:
]1
All com.android.support libraries must use the exact same version
specification (mixing versions can lead to runtime crashes). Found
versions 27.0.2, 26.1.0. Examples include
com.android.support:animated-vector-drawable:27.0.2 and
com.android.support:customtabs:26.1.0
there are some combinations of libraries, or tools and libraries, that
are incompatible, or can lead to bugs. One such incompatibility is
compiling with a version of the Android support libraries that is not
the latest version (or in particular, a version lower than your
targetSdkVersion.)
Solution:
Add explicitly the library with the old version but with a new version number.
in my case com.android.support:customtabs:26.1.0 so I need to add:
build.gradle.kts (Kotlin Build Scripts)
implementation("com.android.support:customtabs:27.0.2")
build.gradle (Groovy Build Scripts)
implementation "com.android.support:customtabs:27.0.2"
ie: Take the library from the second item, and implement it with the version number from the first.
Note: don't forget to press sync now so gradle can rebuild the dependency graph and see if there are any more conflicts.
Explanation:
you may be confused by the error message as don't use customtabs so how I have a conflict!!
well.. you didn't use it directly but one of your libraries uses an old version of customtabs internally, so you need to ask for it directly.
if you curious to know which of your libraries is responsible for the old version and maybe ask the author to update his lib, Run a Gradle dependency report, see the old answer to know how.
Note this
Old answer:
inspired by CommonsWare answer:
Run a Gradle dependency report to see what your full tree of
dependencies is.
From there, you will see which one of your libraries are asking for a different version of the Android Support libraries.
For whatever it is asking for, you can ask for it directly with the
25.2.0 version or use Gradle's other conflict resolution approaches to get the same versions.
Update:
As of gradle plugin version: 3.0 compile has been replaced by implementation or api see this answer for the difference.
hence use instead:
./gradlew -q dependencies app:dependencies --configuration debugAndroidTestCompileClasspath
or for windows cmd:
gradlew -q dependencies app:dependencies --configuration debugAndroidTestCompileClasspath
and search for the conflicted version.
For me, the error disappeared after removing com.google.android.gms:play-services:10.2.0
And only include com.google.android.gms:play-services-location:10.2.0 and com.google.android.gms:play-services-maps:10.2.0 as they are the only two play services that I use.
I think the gms:play-services depend on some old components of the support library, so we need to add them explicitly ourselves.
for AS 3.0 an older.
Run:
./gradlew -q dependencies <module-name>:dependencies --configuration implementation
Example:
./gradlew -q dependencies app:dependencies --configuration implementation
if someone knows a better way in the new gradle plugin please let me know.

Go to project/.idea/libraries folder on your file system and see which libraries are different.
You will have to manually include these libraries with the same version in your build.gradle file.
Then, sync your project.
E.g.:
compile 'com.android.support:appcompat-v7:25.2.0'
// Wrong library version found on 1st point
compile 'com.android.support:customtabs:25.2.0'

For all cases, not just for these versions or libraries:
Pay attention to the little information window that say something about the error, it says the examples that you have to change and add.
In this case:
Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and
com.android.support:mediarouter-v7:24.0.0
Your
com.android.support:animated-vector-drawable:25.1.1
is version 25.1.1, and your
com.android.support:mediarouter-v7:24.0.0
is version 24.0.0, so you have to add the mediarouter with the same version:
com.android.support:mediarouter-v7:25.1.1
And do that for every example that the little information window says, in this case all the libraries that doesn't have the version 25.1.1.
You have to sync the gradle after you fix the indicated library to see the next library and package that you have to change.
IMPORTANT:
If you are not explicitly using one or more specified libraries and it is giving you the error, it means that is being used internally by another library, compile it explicitly anyway.
You also can use another method to see the difference of the versions of all the libraries that you are actually compiling (like run a gradle dependency report or go to your libraries files), the real objetive is compile all the libraries that you are using with the same version.

The best way to solve the problem is implement all 'com.android.support:...' suggested by Android Studio
(Doesn't matter which support versions you are using – 27.1.1, 28.0.0 etc.)
Place the cursor to the error line e.g.
implementation 'com.android.support:appcompat-v7:28.0.0'
Android Studio will suggest you which 'com.android.support:...' is different version than
'com.android.support:appcompat-v7:28.0.0'
Example
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 27.1.0, 27.0.2. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:exifinterface:27.1.0
So add com.android.support:animated-vector-drawable:28.0.0
& com.android.support:exifinterface:28.0.0.
Now sync gradle file.
One by one try to implement all the suggested 'com.android.support:...' until there is no error in this line implementation 'com.android.support:appcompat-v7:28.0.0'
In my case, I added
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:exifinterface:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:customtabs:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
All these dependencies, it could be different for you.

Add this to the very end of your build.gradle (Module:app):
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '25.3.1'
}
}
}
}
Make sure that you replace '25.3.1' with the version of the android support library that you want to use for all the dependencies , it should not be lower than your complile sdk version
than re sync gradle

I had the exact same problem after updating to Android Studio 2.3
Adding this line to dependencies solved my problem:
compile 'com.android.support:customtabs:25.2.0'

A) Run gradle dependencies or ./gradlew dependencies
B) Look at your tree and figure out which of your dependencies is specifying a different support library version for a dependency you don't control.
I didn't realize that this warning also displays if the dependency is completely unused directly by your own code. In my case, Facebook specifies some support libs I wasn't using, you can see below most of those dependencies were overridden by my own specification of 25.2.0, denoted by the -> X.X.X (*) symbols. The card view and custom tabs libs weren't overridden by anyone, so I need to ask for 25.2.0 for those ones myself even though I don't use them.
+--- com.facebook.android:facebook-android-sdk:4.17.0
| +--- com.android.support:support-v4:25.0.0 -> 25.2.0 (*)
| +--- com.android.support:appcompat-v7:25.0.0 -> 25.2.0 (*)
| +--- com.android.support:cardview-v7:25.0.0
| | \--- com.android.support:support-annotations:25.0.0 -> 25.2.0
| +--- com.android.support:customtabs:25.0.0
| | +--- com.android.support:support-compat:25.0.0 -> 25.2.0 (*)
| | \--- com.android.support:support-annotations:25.0.0 -> 25.2.0
| \--- com.parse.bolts:bolts-android:1.4.0 (*)
If gradle has already warned you and given you examples...
Examples include com.android.support:animated-vector-drawable:25.1.1
and com.android.support:mediarouter-v7:24.0.0
... it's even easier if you throw in some grep highlighting for the lower version since gradle dependencies can be quite verbose:
./gradlew dependencies | grep --color -E 'com.android.support:mediarouter-v7|$'

Use variables: Doing something like the following will make it easier for you to ensure that you use the same version with all libraries
dependencies {
ext {
support_library_version = '25.2.0'
google_play_services_version = '10.2.0'
}
//#####################################################################
// Support Library
//#####################################################################
compile "com.android.support:appcompat-v7:${support_library_version}"
compile "com.android.support:palette-v7:${support_library_version}"
compile "com.android.support:design:${support_library_version}"
//#####################################################################
// Google Play Services
//#####################################################################
compile "com.google.android.gms:play-services-auth:${google_play_services_version}"
compile "com.google.android.gms:play-services-ads:${google_play_services_version}"
compile "com.google.android.gms:play-services-analytics:${google_play_services_version}"
//#####################################################################
// Firebase
//#####################################################################
compile "com.google.firebase:firebase-core:${google_play_services_version}"
compile "com.google.firebase:firebase-auth:${google_play_services_version}"
compile "com.google.firebase:firebase-messaging:${google_play_services_version}"
More information on how Google suggests that you handle this versioning can be found in this article: https://developer.android.com/studio/build/index.html#top-level

just add this :
compile 'com.android.support:mediarouter-v7:25.2.0'
Updated for new SDK versions
compile 'com.android.support:mediarouter-v7:28.0.0-alpha3'

As you already seen the all answers and comments above but this answer is to clear something which a new developer might not get easily.
./gradlew -q dependencies app:dependencies --configuration compile
The above line will save your life with no doubt but how to get the exact point from the result of above line.
When you get the all dependency chart or list from the above command then you have to search the conflicting version number which you are getting in your code. please see the below image.
in the above image you can see that 23.4.0 is creating the problem but this we not able to find in our gradle file. So now this version number(23.4.0) will save us. When we have this number then we will find this number in the result of above command result and directly import that dependency directly in our gradle file. Please see the below image to get the clear view.
you can clearly see that com.android.support:cardview-v7:23.4.0 and com.android.support:customtabs:23.4.0 are using the version which is creating the problem. Now just simply copy those line from dependency
list and explicitly use in our gradle file but with the updated version link
implementation "com.android.support:cardview-v7:26.1.0"
implementation "com.android.support:customtabs:26.1.0"

If the same error is on appcompat
implementation 'com.android.support:appcompat-v7:27.0.1'
then adding design solved it.
implementation 'com.android.support:appcompat-v7:27.0.1'
implementation 'com.android.support:design:27.0.1'
For me, adding
implementation 'de.mrmaffen:vlc-android-sdk:2.0.6'
was including appcompat-v7:23.1.1 in
.idea/libraries
without vlc, appcompat alone is enough.

Another way to solve conflicts is just to force the correct version for all dependencies like this:
dependencies {
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
if (details.requested.group == 'com.android.support' && details.requested.name == 'support-v4') {
details.useVersion "27.0.2"
}
}
...
}
https://docs.gradle.org/current/userguide/customizing_dependency_resolution_behavior.html

Use support-v13 instead of support-v4
compile 'com.android.support:support-v13:25.2.0'

add these in app level dependencies
implementation 'com.android.support:asynclayoutinflater:28.0.0'
implementation 'com.android.support:exifinterface:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

My problem is similar to yours.
Here exist an error!
compile 'com.android.support:appcompat-v7:25.3.0'
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.3.0, 24.0.0. Examples include 'com.android.support:animated-vector-drawable:25.3.0' and 'com.android.support:mediarouter-v7:24.0.0'
Seeing this
Examples include 'com.android.support:animated-vector-drawable:25.3.0' and 'com.android.support:mediarouter-v7:24.0.0'
the just add these codes in dependencies, make sure that versions are same.
compile 'com.android.support:animated-vector-drawable:25.3.0'
compile 'com.android.support:mediarouter-v7:25.3.0'

I got the same error after adding compile 'com.google.android.gms:play-services:10.2.4' with compile 'com.android.support:appcompat-v7:25.3.1'.
Adding animated-vector-drawable and mediarouter libs fixed the issue.
compile 'com.google.android.gms:play-services:10.2.4'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:animated-vector-drawable:25.3.1'
compile 'com.android.support:mediarouter-v7:25.3.1'

I had this:

and got this error:
The solutions was easy - the primary dependencies were all correct so the leaves however - any third party dependencies. Removed one by one until found the culprit, and turns out to be facebook! its using version 27.0.2 of the android support libraries. I tried to add the cardview version 27.1.1 but that didn't work eithern the solution was still simple enough.
dependencies {

}

I used these two to solve my problem after upgrading to android studio 2.3
compile 'com.android.support:animated-vector-drawable:25.0.0'
compile 'com.android.support:mediarouter-v7:25.0.0'

I had the same problem before and I got the solution for it.
I just added the libraries that had the another version but with the same version of my support:appcompat.
For your error for example :
All com.android.support libraries must use the exact same version
specification (mixing versions can lead to runtime crashes). Found
versions 25.1.1, 24.0.0. Examples include
com.android.support:animated-vector-drawable:25.1.1 and
com.android.support:mediarouter-v7:24.0.0
*The solution is to compile the versions of these libraries like that :
compile 'com.android.support:mediarouter-v7:25.1.1'
-if another library had the same issue and had another version just compile it with your support:appcompat version
This resolved my problem and I hope it resolves yours.
Best wishes :)

After searching and combining answers, 2018 version of this question and it worked for me:
1) On navigation tab change it to project view
2) Navigate to [YourProjectName]/.idea/libraries/
3) Delete all files starting with Gradle__com_android_support_[libraryName]
E.g: Gradle__com_android_support_animated_vector_drawable_26_0_0.xml
4) In your gradle file define a variable and use it to replace version number like ${variableName}
Def variable:
ext {
support_library_version = '28.0.0' //use the version of choice
}
Use variable:
implementation "com.android.support:cardview-v7:${support_library_version}"
example gradle:
dependencies {
ext {
support_library_version = '28.0.0' //use the version of choice
}
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation "com.android.support:animated-vector-drawable:${support_library_version}"
implementation "com.android.support:appcompat-v7:${support_library_version}"
implementation "com.android.support:customtabs:${support_library_version}"
implementation "com.android.support:cardview-v7:${support_library_version}"
implementation "com.android.support:support-compat:${support_library_version}"
implementation "com.android.support:support-v4:${support_library_version}"
implementation "com.android.support:support-core-utils:${support_library_version}"
implementation "com.android.support:support-core-ui:${support_library_version}"
implementation "com.android.support:support-fragment:${support_library_version}"
implementation "com.android.support:support-media-compat:${support_library_version}"
implementation "com.android.support:appcompat-v7:${support_library_version}"
implementation "com.android.support:recyclerview-v7:${support_library_version}"
implementation "com.android.support:design:${support_library_version}"
}

Very Simple with the new version of the android studio 3.x.
Just copy the version that is less than the current version and add it explicitly with same version number as current version.
Example
Found versions 27.1.1, 27.1.0. Examples include com.android.support:animated-vector-drawable:27.1.1 and com.android.support:exifinterface:27.1.0
Just copy the version com.android.support:exifinterface:27.1.0 and change it to com.android.support:exifinterface:27.1.1 so that it becomes equal to the current version you are using and add it to your gradle dependencies as following.
implementation 'com.android.support:exifinterface:27.1.1'
Note: Once you are done don't forget to click Sync now at the top of the editor.

I have faced this problem after upgrading to android studio 3.4 and sdk version to 28.0.0. Applying below dependency solved the problem for me.
implementation 'com.android.support:exifinterface:28.0.0'

in 2018 update for this error add implementation from project structure
implementation 'com.android.support:support-v13:28.0.0'
in project mode --> External Libraries there you can find your problem, in my case
i am using version 28 and external libraries i found
com.android.support:support-media-compat-26.0.0 and here was the error.
after implementation support v13 and it's working

You have defined any other dependency to compile with version 24.0.0 instead of 25.1.1. Please set all dependencies version the same as 25.1.1.

I had to add the following lines in gradle to remove the error
compile 'com.android.support:animated-vector-drawable:25.2.0'
compile 'com.android.support:preference-v7:25.2.0'
compile 'com.android.support:customtabs:25.2.0'
compile 'com.android.support:cardview-v7:25.2.0'

I ran ./gradlew tasks --all and checked for dependencies that were a different version from the targeted version (25.3.1). You'll get something like this:
app:prepareComAndroidSupportAnimatedVectorDrawable2531Library - Prepare com.android.support:animated-vector-drawable:25.3.1

In this case, I was targeting 25.3.1, and had some dependencies targeting different versions when I ran this command. The trick is to identify the dependencies in this list that are targeting previous versions, and overriding that by importing the most recent version of the dependency in Gradle.

I have the same Problem but I solved this By adding
those Three Lines
implementation 'com.android.support:design:27.1.1'
implementation "com.android.support:customtabs:27.1.1"
implementation 'com.android.support:mediarouter-v7:27.1.1'
now Every thing Works perfectly

Here is my flow to fix this warning
build.gradle
android {
compileSdkVersion ... // must same version (ex: 26)
...
}
dependencies {
...
compile 'any com.android.support... library' // must same version (ex: 26.0.1)
compile 'any com.android.support... library' // must same version (ex: 26.0.1)
...
compile ('a library B which don't use 'com.android.support...' OR use SAME version of 'com.android.support'){
// do nothing
}
...
compile ('a library C which use DIFFERENT 'com.android.support...' (ex:27.0.1) {
// By default, if use don't do anything here your app will choose the higher com.android.support... for whole project (in this case it is 27.0.1)
// If you want to use 26.0.1 use
exclude group: 'com.android.support', module: '...' (ex module: 'appcompat-v7')
exclude group: 'com.android.support', module: 'another module'
...
// If you want to use 27.0.1 do
Upgrade `compileSdkVersion` and all 'com.android.support' to 27.0.1.
(It may be a good solution because the best practice is always use latest `compileSdkVersion`.
However, use 26 or 27 is base on you for example higher library may have bug)
}
}
To view/verify the dependencies of all library in your app
Open terminal and run ./gradlew app:dependencies
To view the dependencies of a specific library in your app follow tutorial here :- How to exclude dependencies of a particular dependency in Gradle
Hope it help

Open the external library of your project you will see that some library still using previous version although you didn't mention those library so my suggestion is just use the particular library version for those it will solve your problem.

I just update my Android Support Repository to (revision: 44.0.0);
then Android SDK tools and Emulator to latest version 25.3.1 from sdk manager> SDK tools
And it solved my problem.

When adding Firebase to project, gradle complains about multiple support library versions [duplicate]

After updating to android studio 2.3 I got this error message.
I know it's just a hint as the app run normally but it's really strange.
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and com.android.support:mediarouter-v7:24.0.0
my gradle:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])

Go to project/.idea/libraries folder on your file system and see which libraries are different.
You will have to manually include these libraries with the same version in your build.gradle file.
Then, sync your project.
E.g.:
compile 'com.android.support:appcompat-v7:25.2.0'
// Wrong library version found on 1st point
compile 'com.android.support:customtabs:25.2.0'

For all cases, not just for these versions or libraries:
Pay attention to the little information window that say something about the error, it says the examples that you have to change and add.
In this case:
Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and
com.android.support:mediarouter-v7:24.0.0
Your
com.android.support:animated-vector-drawable:25.1.1
is version 25.1.1, and your
com.android.support:mediarouter-v7:24.0.0
is version 24.0.0, so you have to add the mediarouter with the same version:
com.android.support:mediarouter-v7:25.1.1
And do that for every example that the little information window says, in this case all the libraries that doesn't have the version 25.1.1.
You have to sync the gradle after you fix the indicated library to see the next library and package that you have to change.
IMPORTANT:
If you are not explicitly using one or more specified libraries and it is giving you the error, it means that is being used internally by another library, compile it explicitly anyway.
You also can use another method to see the difference of the versions of all the libraries that you are actually compiling (like run a gradle dependency report or go to your libraries files), the real objetive is compile all the libraries that you are using with the same version.

The best way to solve the problem is implement all 'com.android.support:...' suggested by Android Studio
(Doesn't matter which support versions you are using – 27.1.1, 28.0.0 etc.)
Place the cursor to the error line e.g.
implementation 'com.android.support:appcompat-v7:28.0.0'
Android Studio will suggest you which 'com.android.support:...' is different version than
'com.android.support:appcompat-v7:28.0.0'
Example
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 27.1.0, 27.0.2. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:exifinterface:27.1.0
So add com.android.support:animated-vector-drawable:28.0.0
& com.android.support:exifinterface:28.0.0.
Now sync gradle file.
One by one try to implement all the suggested 'com.android.support:...' until there is no error in this line implementation 'com.android.support:appcompat-v7:28.0.0'
In my case, I added
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:exifinterface:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:customtabs:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
All these dependencies, it could be different for you.

Add this to the very end of your build.gradle (Module:app):
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '25.3.1'
}
}
}
}
Make sure that you replace '25.3.1' with the version of the android support library that you want to use for all the dependencies , it should not be lower than your complile sdk version
than re sync gradle

I had the exact same problem after updating to Android Studio 2.3
Adding this line to dependencies solved my problem:
compile 'com.android.support:customtabs:25.2.0'

A) Run gradle dependencies or ./gradlew dependencies
B) Look at your tree and figure out which of your dependencies is specifying a different support library version for a dependency you don't control.
I didn't realize that this warning also displays if the dependency is completely unused directly by your own code. In my case, Facebook specifies some support libs I wasn't using, you can see below most of those dependencies were overridden by my own specification of 25.2.0, denoted by the -> X.X.X (*) symbols. The card view and custom tabs libs weren't overridden by anyone, so I need to ask for 25.2.0 for those ones myself even though I don't use them.
+--- com.facebook.android:facebook-android-sdk:4.17.0
| +--- com.android.support:support-v4:25.0.0 -> 25.2.0 (*)
| +--- com.android.support:appcompat-v7:25.0.0 -> 25.2.0 (*)
| +--- com.android.support:cardview-v7:25.0.0
| | \--- com.android.support:support-annotations:25.0.0 -> 25.2.0
| +--- com.android.support:customtabs:25.0.0
| | +--- com.android.support:support-compat:25.0.0 -> 25.2.0 (*)
| | \--- com.android.support:support-annotations:25.0.0 -> 25.2.0
| \--- com.parse.bolts:bolts-android:1.4.0 (*)
If gradle has already warned you and given you examples...
Examples include com.android.support:animated-vector-drawable:25.1.1
and com.android.support:mediarouter-v7:24.0.0
... it's even easier if you throw in some grep highlighting for the lower version since gradle dependencies can be quite verbose:
./gradlew dependencies | grep --color -E 'com.android.support:mediarouter-v7|$'

Use variables: Doing something like the following will make it easier for you to ensure that you use the same version with all libraries
dependencies {
ext {
support_library_version = '25.2.0'
google_play_services_version = '10.2.0'
}
//#####################################################################
// Support Library
//#####################################################################
compile "com.android.support:appcompat-v7:${support_library_version}"
compile "com.android.support:palette-v7:${support_library_version}"
compile "com.android.support:design:${support_library_version}"
//#####################################################################
// Google Play Services
//#####################################################################
compile "com.google.android.gms:play-services-auth:${google_play_services_version}"
compile "com.google.android.gms:play-services-ads:${google_play_services_version}"

//#####################################################################
// Firebase
//#####################################################################
compile "com.google.firebase:firebase-core:${google_play_services_version}"
compile "com.google.firebase:firebase-auth:${google_play_services_version}"
compile "com.google.firebase:firebase-messaging:${google_play_services_version}"
More information on how Google suggests that you handle this versioning can be found in this article: https://developer.android.com/studio/build/index.html#top-level

just add this :
compile 'com.android.support:mediarouter-v7:25.2.0'
Updated for new SDK versions
compile 'com.android.support:mediarouter-v7:28.0.0-alpha3'

As you already seen the all answers and comments above but this answer is to clear something which a new developer might not get easily.
./gradlew -q dependencies app:dependencies --configuration compile
The above line will save your life with no doubt but how to get the exact point from the result of above line.
When you get the all dependency chart or list from the above command then you have to search the conflicting version number which you are getting in your code. please see the below image.
in the above image you can see that 23.4.0 is creating the problem but this we not able to find in our gradle file. So now this version number(23.4.0) will save us. When we have this number then we will find this number in the result of above command result and directly import that dependency directly in our gradle file. Please see the below image to get the clear view.
you can clearly see that com.android.support:cardview-v7:23.4.0 and com.android.support:customtabs:23.4.0 are using the version which is creating the problem. Now just simply copy those line from dependency
list and explicitly use in our gradle file but with the updated version link
implementation "com.android.support:cardview-v7:26.1.0"
implementation "com.android.support:customtabs:26.1.0"

If the same error is on appcompat
implementation 'com.android.support:appcompat-v7:27.0.1'
then adding design solved it.
implementation 'com.android.support:appcompat-v7:27.0.1'
implementation 'com.android.support:design:27.0.1'
For me, adding
implementation 'de.mrmaffen:vlc-android-sdk:2.0.6'
was including appcompat-v7:23.1.1 in
.idea/libraries
without vlc, appcompat alone is enough.

Another way to solve conflicts is just to force the correct version for all dependencies like this:
dependencies {
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
if (details.requested.group == 'com.android.support' && details.requested.name == 'support-v4') {
details.useVersion "27.0.2"
}
}
...
}
https://docs.gradle.org/current/userguide/customizing_dependency_resolution_behavior.html

Use support-v13 instead of support-v4
compile 'com.android.support:support-v13:25.2.0'

add these in app level dependencies
implementation 'com.android.support:asynclayoutinflater:28.0.0'
implementation 'com.android.support:exifinterface:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

My problem is similar to yours.
Here exist an error!
compile 'com.android.support:appcompat-v7:25.3.0'
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.3.0, 24.0.0. Examples include 'com.android.support:animated-vector-drawable:25.3.0' and 'com.android.support:mediarouter-v7:24.0.0'
Seeing this
Examples include 'com.android.support:animated-vector-drawable:25.3.0' and 'com.android.support:mediarouter-v7:24.0.0'
the just add these codes in dependencies, make sure that versions are same.
compile 'com.android.support:animated-vector-drawable:25.3.0'
compile 'com.android.support:mediarouter-v7:25.3.0'

I got the same error after adding compile 'com.google.android.gms:play-services:10.2.4' with compile 'com.android.support:appcompat-v7:25.3.1'.
Adding animated-vector-drawable and mediarouter libs fixed the issue.
compile 'com.google.android.gms:play-services:10.2.4'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:animated-vector-drawable:25.3.1'
compile 'com.android.support:mediarouter-v7:25.3.1'

I had this:

}
and got this error:
The solutions was easy - the primary dependencies were all correct so the leaves however - any third party dependencies. Removed one by one until found the culprit, and turns out to be facebook! its using version 27.0.2 of the android support libraries. I tried to add the cardview version 27.1.1 but that didn't work eithern the solution was still simple enough.
dependencies {

androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

I used these two to solve my problem after upgrading to android studio 2.3
compile 'com.android.support:animated-vector-drawable:25.0.0'
compile 'com.android.support:mediarouter-v7:25.0.0'

I had the same problem before and I got the solution for it.
I just added the libraries that had the another version but with the same version of my support:appcompat.
For your error for example :
All com.android.support libraries must use the exact same version
specification (mixing versions can lead to runtime crashes). Found
versions 25.1.1, 24.0.0. Examples include
com.android.support:animated-vector-drawable:25.1.1 and
com.android.support:mediarouter-v7:24.0.0
*The solution is to compile the versions of these libraries like that :
compile 'com.android.support:mediarouter-v7:25.1.1'
-if another library had the same issue and had another version just compile it with your support:appcompat version
This resolved my problem and I hope it resolves yours.
Best wishes :)

After searching and combining answers, 2018 version of this question and it worked for me:
1) On navigation tab change it to project view
2) Navigate to [YourProjectName]/.idea/libraries/
3) Delete all files starting with Gradle__com_android_support_[libraryName]
E.g: Gradle__com_android_support_animated_vector_drawable_26_0_0.xml
4) In your gradle file define a variable and use it to replace version number like ${variableName}
Def variable:
ext {
support_library_version = '28.0.0' //use the version of choice
}
Use variable:
implementation "com.android.support:cardview-v7:${support_library_version}"
example gradle:
dependencies {
ext {
support_library_version = '28.0.0' //use the version of choice
}
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation "com.android.support:animated-vector-drawable:${support_library_version}"

Very Simple with the new version of the android studio 3.x.
Just copy the version that is less than the current version and add it explicitly with same version number as current version.
Example
Found versions 27.1.1, 27.1.0. Examples include com.android.support:animated-vector-drawable:27.1.1 and com.android.support:exifinterface:27.1.0
Just copy the version com.android.support:exifinterface:27.1.0 and change it to com.android.support:exifinterface:27.1.1 so that it becomes equal to the current version you are using and add it to your gradle dependencies as following.
implementation 'com.android.support:exifinterface:27.1.1'
Note: Once you are done don't forget to click Sync now at the top of the editor.

I have faced this problem after upgrading to android studio 3.4 and sdk version to 28.0.0. Applying below dependency solved the problem for me.
implementation 'com.android.support:exifinterface:28.0.0'

in 2018 update for this error add implementation from project structure
implementation 'com.android.support:support-v13:28.0.0'
in project mode --> External Libraries there you can find your problem, in my case
i am using version 28 and external libraries i found
com.android.support:support-media-compat-26.0.0 and here was the error.
after implementation support v13 and it's working

You have defined any other dependency to compile with version 24.0.0 instead of 25.1.1. Please set all dependencies version the same as 25.1.1.

I had to add the following lines in gradle to remove the error
compile 'com.android.support:animated-vector-drawable:25.2.0'
compile 'com.android.support:preference-v7:25.2.0'
compile 'com.android.support:customtabs:25.2.0'
compile 'com.android.support:cardview-v7:25.2.0'

I ran ./gradlew tasks --all and checked for dependencies that were a different version from the targeted version (25.3.1). You'll get something like this:

In this case, I was targeting 25.3.1, and had some dependencies targeting different versions when I ran this command. The trick is to identify the dependencies in this list that are targeting previous versions, and overriding that by importing the most recent version of the dependency in Gradle.

I have the same Problem but I solved this By adding
those Three Lines
implementation 'com.android.support:design:27.1.1'
implementation "com.android.support:customtabs:27.1.1"
implementation 'com.android.support:mediarouter-v7:27.1.1'
now Every thing Works perfectly

Here is my flow to fix this warning
build.gradle
android {
compileSdkVersion ... // must same version (ex: 26)
...
}
dependencies {
...
compile 'any com.android.support... library' // must same version (ex: 26.0.1)
compile 'any com.android.support... library' // must same version (ex: 26.0.1)
...
compile ('a library B which don't use 'com.android.support...' OR use SAME version of 'com.android.support'){
// do nothing
}
...
compile ('a library C which use DIFFERENT 'com.android.support...' (ex:27.0.1) {
// By default, if use don't do anything here your app will choose the higher com.android.support... for whole project (in this case it is 27.0.1)
// If you want to use 26.0.1 use
exclude group: 'com.android.support', module: '...' (ex module: 'appcompat-v7')
exclude group: 'com.android.support', module: 'another module'
...
// If you want to use 27.0.1 do
Upgrade `compileSdkVersion` and all 'com.android.support' to 27.0.1.
(It may be a good solution because the best practice is always use latest `compileSdkVersion`.
However, use 26 or 27 is base on you for example higher library may have bug)
}
}
To view/verify the dependencies of all library in your app
Open terminal and run ./gradlew app:dependencies
To view the dependencies of a specific library in your app follow tutorial here :- How to exclude dependencies of a particular dependency in Gradle
Hope it help

Open the external library of your project you will see that some library still using previous version although you didn't mention those library so my suggestion is just use the particular library version for those it will solve your problem.

I just update my Android Support Repository to (revision: 44.0.0);
then Android SDK tools and Emulator to latest version 25.3.1 from sdk manager> SDK tools
And it solved my problem.

DataBinding (libraries must use the exact same version specification)

Gradle:
buildscript {
ext.kotlin_version = '1.2.10'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
=========================
ext {
support_version = '27.0.2'
dagger_version = '2.14.1'
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
//kotlin
implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
//support
implementation "com.android.support:appcompat-v7:$support_version"
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
//rx
implementation 'io.reactivex.rxjava2:rxjava:2.1.8'
implementation 'io.reactivex.rxjava2:rxandroid:2.0.1'
//test
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
//Dagger 2
implementation "com.google.dagger:dagger:$dagger_version"
kapt "com.google.dagger:dagger-compiler:$dagger_version"
provided 'org.glassfish:javax.annotation:10.0-b28'
}
It's work well for me, but if I enable DataBinding:
dataBinding {
enabled = true
}
I got a warning com.android.support:appcompat-v7:
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 27.0.2, 21.0.3. Examples include com.android.support:animated-vector-drawable:27.0.2 and com.android.support:support-v4:21.0.3 more... (Ctrl+F1)
and lost method checkSelfPermission in ContextCompat:
ContextCompat.checkSelfPermission(context, android.Manifest.permission.READ_SMS)
Unresolved reference: checkSelfPermission
Gradle file
Why enabling DataBinding leads to such an effect?

Why enabling DataBinding leads to such an effect?
Behind the scenes, dataBinding { enabled = true } adds some dependencies for runtime libraries that support the generated data binding code:
com.android.databinding:adapters
com.android.databinding:baseLibrary
com.android.databinding:library
Those dependencies, in turn, currently have a dependency on an old version of support-v4 (21.0.3). That, in turn, triggers the build error that you are seeing, as Google is trying to enforce that all Support Library artifacts are on the same version.
FWIW, I filed an issue to get this fixed in the data binding framework. I hope that it will be fixed sometime before the heat death of the universe.
The workaround is to add your own dependency on support-v4:
implementation "com.android.support:support-v4:$support_version"
This will cause Gradle to pull in your requested version, which is newer than the one that data binding is seeking, and so Gradle assumes that it will be OK. In truth, it might not be OK, but so far, in my work, I haven't run into any problems.

If you get Gradle Sync Error...
Android dependency 'com.android.support:support-v4' has different
version for the compile (21.0.3) and runtime (27.0.2) classpath. You
should manually set the same version via DependencyResolution
... try api com.android.support:support-v4:27.0.2 instead of implementation com.android.support:support-v4:$support_version.

Android Studio 2.3: libraries must use the exact same exact specification [duplicate]

After updating to android studio 2.3 I got this error message.
I know it's just a hint as the app run normally but it's really strange.
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and com.android.support:mediarouter-v7:24.0.0

Go to project/.idea/libraries folder on your file system and see which libraries are different.
You will have to manually include these libraries with the same version in your build.gradle file.
Then, sync your project.
E.g.:
compile 'com.android.support:appcompat-v7:25.2.0'
// Wrong library version found on 1st point
compile 'com.android.support:customtabs:25.2.0'

For all cases, not just for these versions or libraries:
Pay attention to the little information window that say something about the error, it says the examples that you have to change and add.
In this case:
Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and
com.android.support:mediarouter-v7:24.0.0
Your
com.android.support:animated-vector-drawable:25.1.1
is version 25.1.1, and your
com.android.support:mediarouter-v7:24.0.0
is version 24.0.0, so you have to add the mediarouter with the same version:
com.android.support:mediarouter-v7:25.1.1
And do that for every example that the little information window says, in this case all the libraries that doesn't have the version 25.1.1.
You have to sync the gradle after you fix the indicated library to see the next library and package that you have to change.
IMPORTANT:
If you are not explicitly using one or more specified libraries and it is giving you the error, it means that is being used internally by another library, compile it explicitly anyway.
You also can use another method to see the difference of the versions of all the libraries that you are actually compiling (like run a gradle dependency report or go to your libraries files), the real objetive is compile all the libraries that you are using with the same version.

The best way to solve the problem is implement all 'com.android.support:...' suggested by Android Studio
(Doesn't matter which support versions you are using – 27.1.1, 28.0.0 etc.)
Place the cursor to the error line e.g.
implementation 'com.android.support:appcompat-v7:28.0.0'
Android Studio will suggest you which 'com.android.support:...' is different version than
'com.android.support:appcompat-v7:28.0.0'
Example
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 27.1.0, 27.0.2. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:exifinterface:27.1.0
So add com.android.support:animated-vector-drawable:28.0.0
& com.android.support:exifinterface:28.0.0.
Now sync gradle file.
One by one try to implement all the suggested 'com.android.support:...' until there is no error in this line implementation 'com.android.support:appcompat-v7:28.0.0'
In my case, I added
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:exifinterface:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:customtabs:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
All these dependencies, it could be different for you.

Add this to the very end of your build.gradle (Module:app):
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '25.3.1'
}
}
}
}
Make sure that you replace '25.3.1' with the version of the android support library that you want to use for all the dependencies , it should not be lower than your complile sdk version
than re sync gradle

I had the exact same problem after updating to Android Studio 2.3
Adding this line to dependencies solved my problem:
compile 'com.android.support:customtabs:25.2.0'

A) Run gradle dependencies or ./gradlew dependencies
B) Look at your tree and figure out which of your dependencies is specifying a different support library version for a dependency you don't control.
I didn't realize that this warning also displays if the dependency is completely unused directly by your own code. In my case, Facebook specifies some support libs I wasn't using, you can see below most of those dependencies were overridden by my own specification of 25.2.0, denoted by the -> X.X.X (*) symbols. The card view and custom tabs libs weren't overridden by anyone, so I need to ask for 25.2.0 for those ones myself even though I don't use them.
+--- com.facebook.android:facebook-android-sdk:4.17.0
| +--- com.android.support:support-v4:25.0.0 -> 25.2.0 (*)
| +--- com.android.support:appcompat-v7:25.0.0 -> 25.2.0 (*)
| +--- com.android.support:cardview-v7:25.0.0
| | \--- com.android.support:support-annotations:25.0.0 -> 25.2.0
| +--- com.android.support:customtabs:25.0.0
| | +--- com.android.support:support-compat:25.0.0 -> 25.2.0 (*)
| | \--- com.android.support:support-annotations:25.0.0 -> 25.2.0
| \--- com.parse.bolts:bolts-android:1.4.0 (*)
If gradle has already warned you and given you examples...
Examples include com.android.support:animated-vector-drawable:25.1.1
and com.android.support:mediarouter-v7:24.0.0
... it's even easier if you throw in some grep highlighting for the lower version since gradle dependencies can be quite verbose:
./gradlew dependencies | grep --color -E 'com.android.support:mediarouter-v7|$'

Use variables: Doing something like the following will make it easier for you to ensure that you use the same version with all libraries
dependencies {
ext {
support_library_version = '25.2.0'
google_play_services_version = '10.2.0'
}
//#####################################################################
// Support Library

More information on how Google suggests that you handle this versioning can be found in this article: https://developer.android.com/studio/build/index.html#top-level

just add this :
compile 'com.android.support:mediarouter-v7:25.2.0'
Updated for new SDK versions
compile 'com.android.support:mediarouter-v7:28.0.0-alpha3'

As you already seen the all answers and comments above but this answer is to clear something which a new developer might not get easily.
./gradlew -q dependencies app:dependencies --configuration compile
The above line will save your life with no doubt but how to get the exact point from the result of above line.
When you get the all dependency chart or list from the above command then you have to search the conflicting version number which you are getting in your code. please see the below image.
in the above image you can see that 23.4.0 is creating the problem but this we not able to find in our gradle file. So now this version number(23.4.0) will save us. When we have this number then we will find this number in the result of above command result and directly import that dependency directly in our gradle file. Please see the below image to get the clear view.
you can clearly see that com.android.support:cardview-v7:23.4.0 and com.android.support:customtabs:23.4.0 are using the version which is creating the problem. Now just simply copy those line from dependency
list and explicitly use in our gradle file but with the updated version link
implementation "com.android.support:cardview-v7:26.1.0"
implementation "com.android.support:customtabs:26.1.0"

If the same error is on appcompat
implementation 'com.android.support:appcompat-v7:27.0.1'
then adding design solved it.
implementation 'com.android.support:appcompat-v7:27.0.1'
implementation 'com.android.support:design:27.0.1'
For me, adding
implementation 'de.mrmaffen:vlc-android-sdk:2.0.6'
was including appcompat-v7:23.1.1 in
.idea/libraries
without vlc, appcompat alone is enough.

Another way to solve conflicts is just to force the correct version for all dependencies like this:
dependencies {
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
if (details.requested.group == 'com.android.support' && details.requested.name == 'support-v4') {
details.useVersion "27.0.2"
}
}
...
}
https://docs.gradle.org/current/userguide/customizing_dependency_resolution_behavior.html

Use support-v13 instead of support-v4
compile 'com.android.support:support-v13:25.2.0'

add these in app level dependencies
implementation 'com.android.support:asynclayoutinflater:28.0.0'
implementation 'com.android.support:exifinterface:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

My problem is similar to yours.
Here exist an error!
compile 'com.android.support:appcompat-v7:25.3.0'
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.3.0, 24.0.0. Examples include 'com.android.support:animated-vector-drawable:25.3.0' and 'com.android.support:mediarouter-v7:24.0.0'
Seeing this
Examples include 'com.android.support:animated-vector-drawable:25.3.0' and 'com.android.support:mediarouter-v7:24.0.0'
the just add these codes in dependencies, make sure that versions are same.
compile 'com.android.support:animated-vector-drawable:25.3.0'
compile 'com.android.support:mediarouter-v7:25.3.0'

I got the same error after adding compile 'com.google.android.gms:play-services:10.2.4' with compile 'com.android.support:appcompat-v7:25.3.1'.
Adding animated-vector-drawable and mediarouter libs fixed the issue.
compile 'com.google.android.gms:play-services:10.2.4'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:animated-vector-drawable:25.3.1'
compile 'com.android.support:mediarouter-v7:25.3.1'

I had this:
dependencies {

and got this error:
The solutions was easy - the primary dependencies were all correct so the leaves however - any third party dependencies. Removed one by one until found the culprit, and turns out to be facebook! its using version 27.0.2 of the android support libraries. I tried to add the cardview version 27.1.1 but that didn't work eithern the solution was still simple enough.

I used these two to solve my problem after upgrading to android studio 2.3
compile 'com.android.support:animated-vector-drawable:25.0.0'
compile 'com.android.support:mediarouter-v7:25.0.0'

I had the same problem before and I got the solution for it.
I just added the libraries that had the another version but with the same version of my support:appcompat.
For your error for example :
All com.android.support libraries must use the exact same version
specification (mixing versions can lead to runtime crashes). Found
versions 25.1.1, 24.0.0. Examples include
com.android.support:animated-vector-drawable:25.1.1 and
com.android.support:mediarouter-v7:24.0.0
*The solution is to compile the versions of these libraries like that :
compile 'com.android.support:mediarouter-v7:25.1.1'
-if another library had the same issue and had another version just compile it with your support:appcompat version
This resolved my problem and I hope it resolves yours.
Best wishes :)

After searching and combining answers, 2018 version of this question and it worked for me:
1) On navigation tab change it to project view
2) Navigate to [YourProjectName]/.idea/libraries/
3) Delete all files starting with Gradle__com_android_support_[libraryName]
E.g: Gradle__com_android_support_animated_vector_drawable_26_0_0.xml
4) In your gradle file define a variable and use it to replace version number like ${variableName}
Def variable:
ext {
support_library_version = '28.0.0' //use the version of choice
}
Use variable:
implementation "com.android.support:cardview-v7:${support_library_version}"
example gradle:
dependencies {
ext {
support_library_version = '28.0.0' //use the version of choice
}
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation "com.android.support:animated-vector-drawable:${support_library_version}"
implementation "com.android.support:appcompat-v7:${support_library_version}"
implementation "com.android.support:customtabs:${support_library_version}"
implementation "com.android.support:cardview-v7:${support_library_version}"
implementation "com.android.support:support-compat:${support_library_version}"
implementation "com.android.support:support-v4:${support_library_version}"
implementation "com.android.support:support-core-utils:${support_library_version}"
implementation "com.android.support:support-core-ui:${support_library_version}"
implementation "com.android.support:support-fragment:${support_library_version}"
implementation "com.android.support:support-media-compat:${support_library_version}"
implementation "com.android.support:appcompat-v7:${support_library_version}"
implementation "com.android.support:recyclerview-v7:${support_library_version}"
implementation "com.android.support:design:${support_library_version}"
}

Very Simple with the new version of the android studio 3.x.
Just copy the version that is less than the current version and add it explicitly with same version number as current version.
Example
Found versions 27.1.1, 27.1.0. Examples include com.android.support:animated-vector-drawable:27.1.1 and com.android.support:exifinterface:27.1.0
Just copy the version com.android.support:exifinterface:27.1.0 and change it to com.android.support:exifinterface:27.1.1 so that it becomes equal to the current version you are using and add it to your gradle dependencies as following.
implementation 'com.android.support:exifinterface:27.1.1'
Note: Once you are done don't forget to click Sync now at the top of the editor.

I have faced this problem after upgrading to android studio 3.4 and sdk version to 28.0.0. Applying below dependency solved the problem for me.
implementation 'com.android.support:exifinterface:28.0.0'

in 2018 update for this error add implementation from project structure
implementation 'com.android.support:support-v13:28.0.0'
in project mode --> External Libraries there you can find your problem, in my case
i am using version 28 and external libraries i found
com.android.support:support-media-compat-26.0.0 and here was the error.
after implementation support v13 and it's working

You have defined any other dependency to compile with version 24.0.0 instead of 25.1.1. Please set all dependencies version the same as 25.1.1.

I had to add the following lines in gradle to remove the error
compile 'com.android.support:animated-vector-drawable:25.2.0'
compile 'com.android.support:preference-v7:25.2.0'
compile 'com.android.support:customtabs:25.2.0'
compile 'com.android.support:cardview-v7:25.2.0'

I ran ./gradlew tasks --all and checked for dependencies that were a different version from the targeted version (25.3.1). You'll get something like this:

In this case, I was targeting 25.3.1, and had some dependencies targeting different versions when I ran this command. The trick is to identify the dependencies in this list that are targeting previous versions, and overriding that by importing the most recent version of the dependency in Gradle.

I have the same Problem but I solved this By adding
those Three Lines
implementation 'com.android.support:design:27.1.1'
implementation "com.android.support:customtabs:27.1.1"
implementation 'com.android.support:mediarouter-v7:27.1.1'
now Every thing Works perfectly

Here is my flow to fix this warning
build.gradle
android {
compileSdkVersion ... // must same version (ex: 26)
...
}
dependencies {
...
compile 'any com.android.support... library' // must same version (ex: 26.0.1)
compile 'any com.android.support... library' // must same version (ex: 26.0.1)
...
compile ('a library B which don't use 'com.android.support...' OR use SAME version of 'com.android.support'){
// do nothing
}
...
compile ('a library C which use DIFFERENT 'com.android.support...' (ex:27.0.1) {
// By default, if use don't do anything here your app will choose the higher com.android.support... for whole project (in this case it is 27.0.1)
// If you want to use 26.0.1 use
exclude group: 'com.android.support', module: '...' (ex module: 'appcompat-v7')
exclude group: 'com.android.support', module: 'another module'
...
// If you want to use 27.0.1 do
Upgrade `compileSdkVersion` and all 'com.android.support' to 27.0.1.
(It may be a good solution because the best practice is always use latest `compileSdkVersion`.
However, use 26 or 27 is base on you for example higher library may have bug)
}
}
To view/verify the dependencies of all library in your app
Open terminal and run ./gradlew app:dependencies
To view the dependencies of a specific library in your app follow tutorial here :- How to exclude dependencies of a particular dependency in Gradle
Hope it help

Open the external library of your project you will see that some library still using previous version although you didn't mention those library so my suggestion is just use the particular library version for those it will solve your problem.

I just update my Android Support Repository to (revision: 44.0.0);
then Android SDK tools and Emulator to latest version 25.3.1 from sdk manager> SDK tools
And it solved my problem.

All com.android.support libraries must use the exact same version specification

After updating to android studio 2.3 I got this error message.
I know it's just a hint as the app run normally but it's really strange.
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and com.android.support:mediarouter-v7:24.0.0
my gradle:

Go to project/.idea/libraries folder on your file system and see which libraries are different.
You will have to manually include these libraries with the same version in your build.gradle file.
Then, sync your project.
E.g.:
compile 'com.android.support:appcompat-v7:25.2.0'
// Wrong library version found on 1st point
compile 'com.android.support:customtabs:25.2.0'

For all cases, not just for these versions or libraries:
Pay attention to the little information window that say something about the error, it says the examples that you have to change and add.
In this case:
Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and
com.android.support:mediarouter-v7:24.0.0
Your
com.android.support:animated-vector-drawable:25.1.1
is version 25.1.1, and your
com.android.support:mediarouter-v7:24.0.0
is version 24.0.0, so you have to add the mediarouter with the same version:
com.android.support:mediarouter-v7:25.1.1
And do that for every example that the little information window says, in this case all the libraries that doesn't have the version 25.1.1.
You have to sync the gradle after you fix the indicated library to see the next library and package that you have to change.
IMPORTANT:
If you are not explicitly using one or more specified libraries and it is giving you the error, it means that is being used internally by another library, compile it explicitly anyway.
You also can use another method to see the difference of the versions of all the libraries that you are actually compiling (like run a gradle dependency report or go to your libraries files), the real objetive is compile all the libraries that you are using with the same version.

The best way to solve the problem is implement all 'com.android.support:...' suggested by Android Studio
(Doesn't matter which support versions you are using – 27.1.1, 28.0.0 etc.)
Place the cursor to the error line e.g.
implementation 'com.android.support:appcompat-v7:28.0.0'
Android Studio will suggest you which 'com.android.support:...' is different version than
'com.android.support:appcompat-v7:28.0.0'
Example
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 27.1.0, 27.0.2. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:exifinterface:27.1.0
So add com.android.support:animated-vector-drawable:28.0.0
& com.android.support:exifinterface:28.0.0.
Now sync gradle file.
One by one try to implement all the suggested 'com.android.support:...' until there is no error in this line implementation 'com.android.support:appcompat-v7:28.0.0'
In my case, I added
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:exifinterface:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:customtabs:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
All these dependencies, it could be different for you.

Add this to the very end of your build.gradle (Module:app):
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '25.3.1'
}
}
}
}
Make sure that you replace '25.3.1' with the version of the android support library that you want to use for all the dependencies , it should not be lower than your complile sdk version
than re sync gradle

I had the exact same problem after updating to Android Studio 2.3
Adding this line to dependencies solved my problem:
compile 'com.android.support:customtabs:25.2.0'

A) Run gradle dependencies or ./gradlew dependencies
B) Look at your tree and figure out which of your dependencies is specifying a different support library version for a dependency you don't control.
I didn't realize that this warning also displays if the dependency is completely unused directly by your own code. In my case, Facebook specifies some support libs I wasn't using, you can see below most of those dependencies were overridden by my own specification of 25.2.0, denoted by the -> X.X.X (*) symbols. The card view and custom tabs libs weren't overridden by anyone, so I need to ask for 25.2.0 for those ones myself even though I don't use them.
+--- com.facebook.android:facebook-android-sdk:4.17.0
| +--- com.android.support:support-v4:25.0.0 -> 25.2.0 (*)
| +--- com.android.support:appcompat-v7:25.0.0 -> 25.2.0 (*)
| +--- com.android.support:cardview-v7:25.0.0
| | \--- com.android.support:support-annotations:25.0.0 -> 25.2.0
| +--- com.android.support:customtabs:25.0.0
| | +--- com.android.support:support-compat:25.0.0 -> 25.2.0 (*)
| | \--- com.android.support:support-annotations:25.0.0 -> 25.2.0
| \--- com.parse.bolts:bolts-android:1.4.0 (*)
If gradle has already warned you and given you examples...
Examples include com.android.support:animated-vector-drawable:25.1.1
and com.android.support:mediarouter-v7:24.0.0
... it's even easier if you throw in some grep highlighting for the lower version since gradle dependencies can be quite verbose:
./gradlew dependencies | grep --color -E 'com.android.support:mediarouter-v7|$'

Use variables: Doing something like the following will make it easier for you to ensure that you use the same version with all libraries
dependencies {
ext {
support_library_version = '25.2.0'
google_play_services_version = '10.2.0'
}
//#####################################################################
// Support Library
//#####################################################################

compile "com.google.firebase:firebase-auth:${google_play_services_version}"

More information on how Google suggests that you handle this versioning can be found in this article: https://developer.android.com/studio/build/index.html#top-level

just add this :
compile 'com.android.support:mediarouter-v7:25.2.0'
Updated for new SDK versions
compile 'com.android.support:mediarouter-v7:28.0.0-alpha3'

As you already seen the all answers and comments above but this answer is to clear something which a new developer might not get easily.
./gradlew -q dependencies app:dependencies --configuration compile
The above line will save your life with no doubt but how to get the exact point from the result of above line.
When you get the all dependency chart or list from the above command then you have to search the conflicting version number which you are getting in your code. please see the below image.
in the above image you can see that 23.4.0 is creating the problem but this we not able to find in our gradle file. So now this version number(23.4.0) will save us. When we have this number then we will find this number in the result of above command result and directly import that dependency directly in our gradle file. Please see the below image to get the clear view.
you can clearly see that com.android.support:cardview-v7:23.4.0 and com.android.support:customtabs:23.4.0 are using the version which is creating the problem. Now just simply copy those line from dependency
list and explicitly use in our gradle file but with the updated version link
implementation "com.android.support:cardview-v7:26.1.0"
implementation "com.android.support:customtabs:26.1.0"

If the same error is on appcompat
implementation 'com.android.support:appcompat-v7:27.0.1'
then adding design solved it.
implementation 'com.android.support:appcompat-v7:27.0.1'
implementation 'com.android.support:design:27.0.1'
For me, adding
implementation 'de.mrmaffen:vlc-android-sdk:2.0.6'
was including appcompat-v7:23.1.1 in
.idea/libraries
without vlc, appcompat alone is enough.

Another way to solve conflicts is just to force the correct version for all dependencies like this:

Use support-v13 instead of support-v4
compile 'com.android.support:support-v13:25.2.0'

add these in app level dependencies
implementation 'com.android.support:asynclayoutinflater:28.0.0'
implementation 'com.android.support:exifinterface:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

My problem is similar to yours.
Here exist an error!
compile 'com.android.support:appcompat-v7:25.3.0'
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.3.0, 24.0.0. Examples include 'com.android.support:animated-vector-drawable:25.3.0' and 'com.android.support:mediarouter-v7:24.0.0'
Seeing this
Examples include 'com.android.support:animated-vector-drawable:25.3.0' and 'com.android.support:mediarouter-v7:24.0.0'
the just add these codes in dependencies, make sure that versions are same.
compile 'com.android.support:animated-vector-drawable:25.3.0'
compile 'com.android.support:mediarouter-v7:25.3.0'

I got the same error after adding compile 'com.google.android.gms:play-services:10.2.4' with compile 'com.android.support:appcompat-v7:25.3.1'.
Adding animated-vector-drawable and mediarouter libs fixed the issue.
compile 'com.google.android.gms:play-services:10.2.4'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:animated-vector-drawable:25.3.1'
compile 'com.android.support:mediarouter-v7:25.3.1'

I had this:
dependencies {

}
and got this error:
The solutions was easy - the primary dependencies were all correct so the leaves however - any third party dependencies. Removed one by one until found the culprit, and turns out to be facebook! its using version 27.0.2 of the android support libraries. I tried to add the cardview version 27.1.1 but that didn't work eithern the solution was still simple enough.
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])

androidTestImplementation 'com.android.support.test:runner:1.0.1'

}

I used these two to solve my problem after upgrading to android studio 2.3
compile 'com.android.support:animated-vector-drawable:25.0.0'
compile 'com.android.support:mediarouter-v7:25.0.0'

I had the same problem before and I got the solution for it.
I just added the libraries that had the another version but with the same version of my support:appcompat.
For your error for example :
All com.android.support libraries must use the exact same version
specification (mixing versions can lead to runtime crashes). Found
versions 25.1.1, 24.0.0. Examples include
com.android.support:animated-vector-drawable:25.1.1 and
com.android.support:mediarouter-v7:24.0.0
*The solution is to compile the versions of these libraries like that :
compile 'com.android.support:mediarouter-v7:25.1.1'
-if another library had the same issue and had another version just compile it with your support:appcompat version
This resolved my problem and I hope it resolves yours.
Best wishes :)

After searching and combining answers, 2018 version of this question and it worked for me:
1) On navigation tab change it to project view
2) Navigate to [YourProjectName]/.idea/libraries/
3) Delete all files starting with Gradle__com_android_support_[libraryName]
E.g: Gradle__com_android_support_animated_vector_drawable_26_0_0.xml
4) In your gradle file define a variable and use it to replace version number like ${variableName}
Def variable:
ext {
support_library_version = '28.0.0' //use the version of choice
}
Use variable:
implementation "com.android.support:cardview-v7:${support_library_version}"
example gradle:
dependencies {
ext {
support_library_version = '28.0.0' //use the version of choice
}
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation "com.android.support:animated-vector-drawable:${support_library_version}"
implementation "com.android.support:appcompat-v7:${support_library_version}"
implementation "com.android.support:customtabs:${support_library_version}"
implementation "com.android.support:cardview-v7:${support_library_version}"
implementation "com.android.support:support-compat:${support_library_version}"
implementation "com.android.support:support-v4:${support_library_version}"
implementation "com.android.support:support-core-utils:${support_library_version}"
implementation "com.android.support:support-core-ui:${support_library_version}"
implementation "com.android.support:support-fragment:${support_library_version}"
implementation "com.android.support:support-media-compat:${support_library_version}"
implementation "com.android.support:appcompat-v7:${support_library_version}"
implementation "com.android.support:recyclerview-v7:${support_library_version}"
implementation "com.android.support:design:${support_library_version}"
}

Very Simple with the new version of the android studio 3.x.
Just copy the version that is less than the current version and add it explicitly with same version number as current version.
Example
Found versions 27.1.1, 27.1.0. Examples include com.android.support:animated-vector-drawable:27.1.1 and com.android.support:exifinterface:27.1.0
Just copy the version com.android.support:exifinterface:27.1.0 and change it to com.android.support:exifinterface:27.1.1 so that it becomes equal to the current version you are using and add it to your gradle dependencies as following.
implementation 'com.android.support:exifinterface:27.1.1'
Note: Once you are done don't forget to click Sync now at the top of the editor.

I have faced this problem after upgrading to android studio 3.4 and sdk version to 28.0.0. Applying below dependency solved the problem for me.
implementation 'com.android.support:exifinterface:28.0.0'

in 2018 update for this error add implementation from project structure
implementation 'com.android.support:support-v13:28.0.0'
in project mode --> External Libraries there you can find your problem, in my case
i am using version 28 and external libraries i found
com.android.support:support-media-compat-26.0.0 and here was the error.
after implementation support v13 and it's working

You have defined any other dependency to compile with version 24.0.0 instead of 25.1.1. Please set all dependencies version the same as 25.1.1.

I had to add the following lines in gradle to remove the error
compile 'com.android.support:animated-vector-drawable:25.2.0'
compile 'com.android.support:preference-v7:25.2.0'
compile 'com.android.support:customtabs:25.2.0'
compile 'com.android.support:cardview-v7:25.2.0'

I ran ./gradlew tasks --all and checked for dependencies that were a different version from the targeted version (25.3.1). You'll get something like this:

In this case, I was targeting 25.3.1, and had some dependencies targeting different versions when I ran this command. The trick is to identify the dependencies in this list that are targeting previous versions, and overriding that by importing the most recent version of the dependency in Gradle.

I have the same Problem but I solved this By adding
those Three Lines
implementation 'com.android.support:design:27.1.1'
implementation "com.android.support:customtabs:27.1.1"
implementation 'com.android.support:mediarouter-v7:27.1.1'
now Every thing Works perfectly

Here is my flow to fix this warning
build.gradle
android {
compileSdkVersion ... // must same version (ex: 26)
...
}
dependencies {
...
compile 'any com.android.support... library' // must same version (ex: 26.0.1)
compile 'any com.android.support... library' // must same version (ex: 26.0.1)
...
compile ('a library B which don't use 'com.android.support...' OR use SAME version of 'com.android.support'){
// do nothing
}
...
compile ('a library C which use DIFFERENT 'com.android.support...' (ex:27.0.1) {
// By default, if use don't do anything here your app will choose the higher com.android.support... for whole project (in this case it is 27.0.1)
// If you want to use 26.0.1 use
exclude group: 'com.android.support', module: '...' (ex module: 'appcompat-v7')
exclude group: 'com.android.support', module: 'another module'
...
// If you want to use 27.0.1 do
Upgrade `compileSdkVersion` and all 'com.android.support' to 27.0.1.
(It may be a good solution because the best practice is always use latest `compileSdkVersion`.
However, use 26 or 27 is base on you for example higher library may have bug)
}
}
To view/verify the dependencies of all library in your app
Open terminal and run ./gradlew app:dependencies
To view the dependencies of a specific library in your app follow tutorial here :- How to exclude dependencies of a particular dependency in Gradle
Hope it help

Open the external library of your project you will see that some library still using previous version although you didn't mention those library so my suggestion is just use the particular library version for those it will solve your problem.

I just update my Android Support Repository to (revision: 44.0.0);
then Android SDK tools and Emulator to latest version 25.3.1 from sdk manager> SDK tools
And it solved my problem.
