Execution failed for task ': app: transformClassesWithDexForDebug' when implementing Google for Android

Question

I am trying to implement Google for Android and I am following the instructions through

https://developers.google.com/identity/sign-in/android/start-integrating

But when creating the application, I get the following error.

My top level gradle is

         dependencies {

             classpath 'com.google.gms: google-services: 1.4.0-beta3'

             // NOTE: Do not place your application dependencies here;  they belong
             // in the individual module build.gradle files
         }
     }

     allprojects {
         repositories {
             jcenter ()
         }
     }
    

My app level gradle is <pre> apply plugin: 'com.android.application' apply plugin: 'com.google.gms.google-services' android { compileSdkVersion 23 buildToolsVersion '23.0.1' defaultConfig { applicationId "com.questo.rugved.questo" minSdkVersion 15 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']) compile 'com.android.support:appcompat-v7:23.0.1' compile 'com.android.support:design:23.+' compile 'com.google.android.gms:play-services-identity:8.1.0' compile 'com.google.android.gms:play-services-plus:8.1.0' } 

Please, help.

Perhaps this link will help you. link

It helped me:

 android { ... defaultConfig { ... multiDexEnabled true } } 

Answer 2

This issue occurs because of multiple dependency inclusion. You include the dependency that is already specified in the build.gradle file. For example:

 compile 'com.google.android.gms:play-services:9.0.2' compile 'com.google.android.gms:play-services-identity:9.0.2' 

the above dependency specification will create this problem, since game services include everything, including character identification, and thus, the same dependency is included several times.

The recommended option is only to include the dependencies that you really need. If you need the location of the game services and maps, include only these dependencies as:

 compile 'com.google.android.gms:play-services-location:9.0.2' compile 'com.google.android.gms:play-services-maps:9.0.2' 

Without including everything with 'com.google.android.gms: play-services: 9.0.2'.

In your particular case, I suspect that a conflict occurs between the google services of the top-level gradle file and play-services-identity and play-services-plus in the gradle application level file. Using only the services you need to enable multiple inclusion will solve your problem.

In general, you should not use "multiDexEnabled true" unless you have a strong and legitimate reason. Using this without knowing the actual problem means you are getting around the problem. You allow multiple overlapping dependencies giving a potential source of api conflicts and a larger apk size.

Adding

  dexOptions { incremental = true; preDexLibraries = false javaMaxHeapSize "4g" // 2g should be also OK } 

in with inroid in build.gradle works for me.

Answer 4

There was the same problem.
Mine has been fixed by setting the JAVA_HOME variable in java 8 jdk

 export JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/"
