Error:Android Dex: [R         


        

Answer 1

I had same issue in Android Studio 2.3, in my case I had a mixture of version numbers which threw the build out, I changed:

dependencies {
    compile 'com.google.android.gms:play-services-wearable:7.5.0'
    compile 'com.google.android.gms:play-services-analytics:7.5.0'
    compile 'com.google.android.gms:play-services-drive:8.4.0'
}

to

dependencies {
    compile 'com.google.android.gms:play-services-wearable:8.4.0'
    compile 'com.google.android.gms:play-services-analytics:8.4.0'
    compile 'com.google.android.gms:play-services-drive:8.4.0'
}
