Java – multiple DEX files define LCOM / Google / Android / GMS / ads / identifier / advertising idclient $info;

I received this error while trying to compile the project on Android studio

app:transformClassesWithDexForDebug Failed
Error:Error converting bytecode to dex:
Cause: com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/ads/identifier/AdvertisingIdClient$Info;
Error:Execution Failed for task ':app:transformClassesWithDexForDebug'.

    `com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/java-7-openjdk-i386/bin/java'' finished with non-zero exit value 2`

Here is my build.gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"
    useLibrary 'org.apache.http.legacy'

    defaultConfig {
        applicationId "paritosh.d9.groceries"
        minSdkVersion 17
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.mcxiaoke.volley:library-aar:1.0.0'
    compile 'com.android.support:design:23.1.1'
    compile 'com.facebook.android:facebook-android-sdk:4.11.0'
    compile 'com.facebook.android:audience-network-sdk:4.7.0'
    compile 'com.google.android.gms:play-services-location:8.4.0'
    compile 'com.google.android.gms:play-services-auth:8.4.0'
}

I've been trying to solve this problem. I tried to delete my playback service dependency, but it can't solve the problem. Please help me solve this problem. Thank you

resolvent:

You have duplicate dependencies - the two classes are the same. You should know which library contains the one that should be excluded. To do this, you need to run the next line in the console:

./gradlew app:androidDependencies

In addition, you can perform the same operation on the gradle plug-in in Android Studio:

The output will be as follows:

+--- com.android.support:multidex:1.0.1
+--- io.realm:realm-android-library:1.0.0
|    \--- com.getkeepsafe.relinker:relinker:1.2.1
+--- com.android.support:appcompat-v7:23.3.0
|    +--- com.android.support:animated-vector-drawable:23.3.0
|    |    \--- com.android.support:support-vector-drawable:23.3.0
|    \--- com.android.support:support-vector-drawable:23.3.0
+--- com.android.support:design:23.3.0
|    +--- com.android.support:appcompat-v7:23.3.0
|    |    +--- com.android.support:animated-vector-drawable:23.3.0
|    |    |    \--- com.android.support:support-vector-drawable:23.3.0
|    |    \--- com.android.support:support-vector-drawable:23.3.0
|    \--- com.android.support:recyclerview-v7:23.3.0

Find and exclude duplicates of GMS lib as follows:

 compile(group: 'com.google.android.gms', name: 'play-services-gcm', version: "8.4.0") {
        exclude(group: 'com.google.android.gms', module: 'play-services-base')
        exclude(group: 'com.google.android.gms', module: 'play-services-basement')
    }

If you still can't solve the problem, please let me know

./gradlew app:androidDependencies
