Generate APK signature Error: error converting bytecode to dex and 1 more

Question

When I clean / rebuild a project or even launch an application, it does not return any errors. But when I create a signed APK, it returns two errors.

Error:Error converting bytecode to dex: Cause: com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/internal/zzox; 

And this one

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

Below is the code from the build.gradle file.

 apply plugin: 'com.android.application' android { compileSdkVersion 24 buildToolsVersion "22.0.1" defaultConfig { applicationId "com.wildlife.dbd" minSdkVersion 16 targetSdkVersion 24 versionCode 10 versionName "2.2.2" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } apply plugin: 'com.google.gms.google-services' dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:24.0.0' compile 'com.android.support:design:24.0.0' // FB Ads compile 'com.facebook.android:audience-network-sdk:4.10.0' // Analytics compile 'com.google.android.gms:play-services-analytics:9.0.0' } 

Answer 1

The Facebook audience network will also play game services, so you will have to exclude it:

I don’t remember exactly what Facebook addiction is, so your line of analytics may not be complete enough for the audience’s network to function properly. You might want to add all the playback services as follows: compile 'com.google.android.gms:play-services:9.2.1' and remove the analytics.

Or, if you see exactly what kind of dependencies Facebook requires, you can grab the right ones here .

 compile ('com.facebook.android:audience-network-sdk:4.10.0') { exclude group: 'com.google.android.gms' }
