问题:

In my project i have implemented play-services-games,first I have tried to add
compile 'com.google.android.gms:play-services:10.0.1'
but i got into some troubles and the solutions that i found was to compile only the needed library compile 'com.google.android.gms:play-services-games:10.0.1'
and all was great but when I've tried to add play-services-ads things got messy,I have added
compile 'com.google.android.gms:play-services-ads:10.0.1'
Now i get

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/internal/zzqv.class

Here is my build.gradle

apply plugin: 'com.android.application'  android {     compileSdkVersion 25     buildToolsVersion "25.0.1"     defaultConfig {         applicationId "com.apps.fightersam"         minSdkVersion 15         targetSdkVersion 25         versionCode 1         versionName "1.0"         testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"         multiDexEnabled true     }     buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  dependencies {     compile fileTree(dir: 'libs', include: ['*.jar'])     compile name: 'unity-ads', ext: 'aar'     compile 'com.android.support:appcompat-v7:25.1.0'     compile 'com.android.support:design:25.1.0'     compile 'com.google.android.gms:play-services-games:10.0.1'     compile 'com.google.android.gms:play-services-ads:10.0.1'      compile project(':BaseGameUtils') } repositories {     flatDir {         dirs 'libs'     } }

You have to exclude the duplicate use of an internal transitive dependency. To find out which

gradle -q dependencies 

This will give you the dependency tree. Then you can do something like

  compile('com.example.m:m:1.0') {      exclude group: 'org.unwanted', module: 'x    }

I was using the latest version of FirebaseUI 2.0.0 which seemed to be incompatible with google-services:3.0.0. Therefore I downgraded FirebaseUI version to 1.2.0 and added the following code to Project level build.gradle:

allprojects {     repositories {         jcenter()          // Add the following         maven {             url 'https://maven.fabric.io/public'         }     } }

I had a problem like this, but in my case I have two versions of the Google libraries being imported. In your case

delete this from your dependencies:

compile 'com.google.android.gms:play-services-ads:10.0.1' 

Because it's imported from:

compile name: 'unity-ads', ext: 'aar' 

Or do the opposite delet unity-ads and let compile 'com.google.android.gms:play-services-ads:10.0.1'

goodluck

In my case Downgrading Both 'com.google.android.gms:play-services-games:10.0.1' and 'com.google.android.gms:play-services-ads:10.0.1'
To 'com.google.android.gms:play-services-games:9.0.1' and 'com.google.android.gms:play-services-ads:9.0.1' did the trick !
