Android Gradle Error “java finished with non-zero exit value 2”

In this blog,

I have talked about the reason behind Android Gradle error.

“java finished with non-zero exit value 2”

This is a very general problem when we have used many libraries to build our android project.

So, I will give the answer and the some suggestions for avoiding this gradle error.

Explaination:

This issue is quite possibly due to exceeding the 65K methods dex limit imposed by Android.

And if you had put a unnecessary compile library code in build.gradle.

Java

dependencies { compile 'com.google.android.gms:play-services:8.3.0' }

1 2 3

dependencies {     compile 'com.google.android.gms:play-services:8.3.0' }

Which was causing over 65k methods, so removed it,  used only neccessary compile library code gradle sync, cleaned project, and then ran again and then this error stopped. I needed just maps, analytics and gcm so i put these lines and synced project

Java

dependencies { compile 'com.google.android.gms:play-services-maps:8.3.0' compile 'com.google.android.gms:play-services-gcm:8.3.0' compile 'com.google.android.gms:play-services-analytics:8.3.0' }

1 2 3 4 5

dependencies {     compile 'com.google.android.gms:play-services-maps:8.3.0'     compile 'com.google.android.gms:play-services-gcm:8.3.0'     compile 'com.google.android.gms:play-services-analytics:8.3.0' }

 

After that your problem should be solved.

Note: If you want to count the total methods in your project then you can use the following link

By simply upload your apk file.

After all this If still your project is giving this error, So you have to enable the multidex in your project.

defaultConfig { // Enabling multidex . multiDexEnabled true } dexOptions { incremental true javaMaxHeapSize "2048M" jumboMode = true } dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile 'com.android.support:multidex:1.0.1' }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

defaultConfig {    // Enabling multidex .     multiDexEnabled true }   dexOptions {     incremental true     javaMaxHeapSize "2048M"     jumboMode = true }   dependencies {     compile fileTree(include: ['*.jar'], dir: 'libs')     compile 'com.android.support:multidex:1.0.1' }

And create a class

Java

dependencies { compile 'com.google.android.gms:play-services-maps:8.3.0' compile 'com.google.android.gms:play-services-gcm:8.3.0' compile 'com.google.android.gms:play-services-analytics:8.3.0' }

1 2 3 4 5

dependencies {     compile 'com.google.android.gms:play-services-maps:8.3.0'     compile 'com.google.android.gms:play-services-gcm:8.3.0'     compile 'com.google.android.gms:play-services-analytics:8.3.0' }

 

that extends Application class

Java

@Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); //include this method MultiDex.install(this); }

1 2 3 4 5 6

@Override protected void attachBaseContext(Context base) {     super.attachBaseContext(base);     //include this method     MultiDex.install(this); }

 

also add in OnCreate method too

@Override public void onCreate() { //include this method MultiDex.install(this); super.onCreate(); }

1 2 3 4 5

@Override public void onCreate() {     //include this method     MultiDex.install(this); super.onCreate(); }
