Android, Build Successful, but apk build (subsequent run) fails

Question

I recently upgraded to Android studio 1.2 beta. Projects that compiled fine earlier, broke. I had to make some modifications in the gradle file to get the project compile again. Now the build is successful, however, when I try to build an apk the build fails.

Here are the project details.

Gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion '22.0.1'
    defaultConfig {
        applicationId "mcc.abcd"
        minSdkVersion 16
        targetSdkVersion 22
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:22.0.0'
    compile 'com.google.android.gms:play-services:7.0.0'
    //compile files('libs/google-play-services.jar')
    compile project(':app:libraries:PebbleKitAndroid:app')
    compile project(':app:libraries:Weka-for-Android-master:app')
}

Build Error

I have already tried changing buildToolsVersion, sdk versions, etc., but no success yet. Please help.

Answer 1

Reason for the failure is on the second line of your build output - "com.android.dex.DexIndexOverflowException: Cannot merge new index 68094 into a non-jumbo instruction!"

What this means is that you have hit the maximum method limit with your application, com.google.android.gms:play-services is huge (as in lots of methods)

Easiest solution is to just use the components of Play services that you actually need as described in official docs, so for example

compile 'com.google.android.gms:play-services-gcm:7.0.0'

instead of your

compile 'com.google.android.gms:play-services:7.0.0'
