Android libraries: versions conflict issue

I've the below dependence in my Android app build.gradle
compileSdkVersion 25
buildToolsVersion "25.0.2"
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:design:25.0.0'
compile 'com.android.support:appcompat-v7:25.0.0'
compile 'com.google.android.gms:play-services:10.0.1'
compile 'com.google.firebase:firebase-core:10.0.1'
compile 'com.google.firebase:firebase-messaging:10.0.1'
compile 'com.firebase:firebase-jobdispatcher-with-gcm-dep:0.6.0'
compile 'com.google.firebase:firebase-appindexing:10.0.1'
compile 'com.google.firebase:firebase-ads:10.0.1'
testCompile 'junit:junit:4.12'
compile 'com.android.support:multidex:1.0.1'
}
but getting an error about versions compatibility, as shown below, what is the one to be changed here, i could not figure it out :(

I had same problem what i did was compile the higher version of libraries ,which were creating this error,in app:gradle only.
for example in your case
compile 'com.android.support:mediarouter-v7:25.0.0'
Add this in app:gradle.
There may be more like this mediarouter libraries if it still give error add them jst like this(making them higher version).

First you need to find out where's what consists of a conflicting version of the library. The easiest way to do so is to:
Open Terminal pane in your Android Studio.
Type in: ./gradlew androidDependencies
Find the row that represents the ENCLOSING library consisting of a conflict.
Then just use exclude statement for the conflicting library, like so:
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
(the example assuming com.android.support.test.espresso:espresso-core:2.2.2 was the ENCLOSING library, and com.android.support:support-annotations being the conflict)

Firebase dependencies set up correctly but still cannot resolve

New to firebase but when I try to use private FirebaseAuth mAuth; as stated in their Email Auth guide it is not able to resolve. I have set up firebase in the project and it says I have done it correctly.
Do I need to import something on that java file?
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.0'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.google.firebase:firebase-auth:10.2.0'
compile 'com.android.support:design:25.3.0'
testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'

You need to add:
import com.google.firebase.auth.FirebaseAuth;
Android Studio will help you with unresolved references like this one. Click on the unresolved symbol and enter Alt+Enter. The needed import will be automatically added.

How to compare two intent using assertj-android

Hi I am using roboelectric for unit testing of my android application. I want to compare expected intent and actual intent using assertj-android. I have added required dependency of assertj-android, even though I have done Gradle sync multiple times but still unable to import org.assertj.android.api.content.IntentAssert.
What could be the issue ? Any idea ? Thanks in advance
build.gradle
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.1.1'
testCompile 'junit:junit:4.12'
testCompile 'org.robolectric:robolectric:3.2.2'
testCompile 'org.khronos:opengl-api:gl1.1-android-2.1_r1'
androidTestCompile 'com.squareup.assertj:assertj-android:1.1.1'
}

AssertJ dependency in your build.gradle is for androidTest and it should be for test since you're using Robolectric?

Vitamio crash on LibChecker. Added Vitamio using gradle

I add viatmio library using gradle in android studio V2.2 .
It crash at
if (!LibsChecker.checkVitamioLibs(this))
with exception like
couldn't find "libvinit.so"
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'me.neavo:vitamio:4.2.2'
testCompile 'junit:junit:4.12'
}
Need any suggestions or correction.
Thanks

Download latest version of Vitamio from Official Web site and Add this line to initiate
Vitamio.isInitialized(this);

Android Studio cannot resolve symbol 'TabLayout'

Cannot resolve symbol TabLayout ? How to clear this error? Please help me. I already imported import android.support.design.widget.TabLayout;

Had a similar problem, to fix this in Android Studio (AS) I went Build->Clean Project and AS sorted everything out. Make sure in your build.gradle file under dependencies that you have:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:your_api_version_number.0.0'
compile 'com.android.support:design:+'
}

I solved the issue Manually by adding the following two lines:
implementation 'com.android.support:support-v4:22.2.0'
implementation 'com.android.support:design:22.2.0'
under dependencies in \app\build.gradle worked for me.
Note: Your all the support libraries have to be the same version i.e. appcompat-v7 and support-v4 to same version e.g. 23.0.1; otherwise you can get this error
java.lang.NoClassDefFoundError: android.support.v7.internal.widget.TintManager`
after code build

Under Gradle Scripts,
Open build.gradle (Module: app)
Inside of dependencies add
compile 'com.android.support:design:25.3.1'
There may be a newer version of the library available, the android studio lint check may detect that.
The full dependencies area may look like this for reference. The above line is the only one I manually added.
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
compile 'com.android.support:design:25.3.1'
}
An above answer suggested adding
compile 'com.android.support:design:+'
Which is kind of dangerous because it always uses the latest library, you may have trouble isolating bugs with automatic library updates happening in the background.

Android Studio no longer uses "compile", they use "implementation".
Be sure to include the code below when you go to Build Gradle>dependencies{
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:support-v4:27.1.1'
implementation 'com.android.support:design:27.1.1'
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'
}

For Android API Level 29+, add the following dependency in build.gradle (Module:app):
dependencies {
implementation 'com.google.android.material:material:1.0.0'
}
If there is a newer version available, Android Studio will prompt you to use the newest one.

I solve it by Open build.gradle (Module: app) and add
implementation 'com.android.support:design:+'
