add this 3 lines to your dependency build.gradle

android: gradle: same version for dependencies

I want to add fcm to my android project. Following the guide, I added firebase to my app and inserted the dependency. But now I get the error
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 26.1.0. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:support-media-compat:26.1.0
on the appcompat dependency(or maybe I just haven't noticed it before)
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "myApp.ginso.com.azul"
minSdkVersion 26
targetSdkVersion 28

}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.google.firebase:firebase-messaging:17.3.4'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}
Can anyone tell me, what I have to change?

Issue is that espresso-core is using older dependency of support library group. Increase it to latest version (3.0.2 or whatever latest is) or use below code instead of your existing code to explicitly remove support group from it:
androidTestImplementation ('com.android.support.test.espresso:espresso-core:3.0.1') {
exclude group: "com.android.support"
}
Hope this will solve your problem.

Some of your libraries have used an older version of dependencies.
To resolve this add this dependency and try again
implementation 'com.android.support:support-media-compat:28.0.0'

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

I keep receiving an error: All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 27.1.1, 25.2.0. Examples include com.android.support:animated-vector-drawable:27.1.1 and com.android.support:support-media-compat:25.2.0
This error shows on com.android.support:appcompat-v7:27.1.1 line.
I added Firebase to my app and it shows that these dependencies can be updated to newer versions.
I know about other same questions but appcompat and Firebase versions are different.
Here is the code in app/build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "com.airliner.chatting"
minSdkVersion 16
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
implementation 'com.google.firebase:firebase-auth:11.8.0'
implementation 'com.google.firebase:firebase-database:11.8.0'
implementation 'com.google.firebase:firebase-messaging:11.8.0'
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'
}
apply plugin: 'com.google.gms.google-services'

I solved it by adding
implementation 'com.android.support:support-media-compat:27.1.1'
implementation 'com.android.support:support-v4:27.1.1'
Just copy the second library name from the error message, add it to dependencies and change it's version to the same as the first library name.

problems with 'com.android.support:appcompat-v7.27.1.1' in the gradle file

This is my dependencies file and there is an underlined red colored text on the compile 'com.android.support:appcompat-v7.27.1.1'
apply plugin: 'com.android.application'

defaultConfig {

This because of this I am having problems changing themes in the styles.xml

when you hover over the red line it may show you the image like this which I have attached below.
What it tells you is there is a conflict of the version in some libraries so it suggests us to add those. For my case first, it showed for CardView and then for Design. So I added to it. Below is the code for it.
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.payumoney.sdkui:plug-n-play:1.2.0'
implementation 'com.android.support:cardview-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
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'
}
so kindly add those it may be 2 or more than that.
Hope that helps.

In Android Studio 3.0 ,the compile configuration is now deprecated and should be replaced by implementation or api.
Just replace:
implementation 'com.android.support:appcompat-v7.27.1.1'
compile with implementation
testCompile with testImplementation.
debugCompile with debugImplementation.
androidTestCompile with androidTestImplementation.
compileOnly is still valid. It was added in 3.0 to replace provided and not compile.
for more information read this gradel doc

Reason of fail
You are using incompatible version of firebase with 27.1.1 support version.
Current version > 16.0.0 and you use 11.6.0.
Solution
Update your firebase dependencies versions. I suggest update target sdk version also.
Below is updated gradle as of date 1-10-2018, you can see firebase page to check latest version.
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.abc.mcaproject"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7.28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.google.firebase:firebase-database:16.0.2'
implementation 'com.google.firebase:firebase-messaging:17.3.2'
implementation 'com.google.firebase:firebase-auth:16.0.3'
implementation 'com.google.firebase:firebase-storage:16.0.2'
}
apply plugin: 'com.google.gms.google-services'
Suggestion
Migrate to androidx because Android will not update support libraries after version 28.0.0.

just goto-> files->project structures->app->flavors
change your min SDK version and target SDK version to "API 27:"
then go to properties and check that your compile SDK version has also changed to the above version which you selected.
This worked for me.

Appcompat is not able to compile due to some version error [duplicate]

ANd when i am running the app, app crashes on run time displaying the following error
java.lang.NoSuchMethodError: No static method getFont(Landroid/content/Context;ILandroid/util/TypedValue;ILandroid/widget/TextView;)Landroid/graphics/Typeface; in class Landroid/support/v4/content/res/ResourcesCompat; or its super classes (declaration of 'android.support.v4.content.res.ResourcesCompat' appears in /data/app/com.example.tapesh.tapu_chat-2/base.apk)

getFont() will work from Android 'O'(26.0.0-beta1) version
So update your build tool version to: "27.0.2"
Example: build.gradle
compileSdkVersion 27
buildToolsVersion "27.0.2"
targetSdkVersion 27
Updated Dependencies:
compile 'com.android.support:appcompat-v7:27.0.2'
compile 'com.android.support:design:27.0.2'
compile 'com.android.support:customtabs:27.0.2'
Source

I believe you are using build tool version 26.0.2 and you are using some support dependencies. Try this.
For example:
android {
buildToolsVersion "26.0.2"
}
and
dependencies {
implementation 'com.android.support:support-v4:26.0.2'
implementation 'com.android.support:appcompat-v7:26.0.2'
implementation 'com.android.support:recyclerview-v7:26.0.2'
implementation 'com.android.support:support-v13:26.0.2'
}
