compile 'com.android.support:support-v4:22.2.0'
compile 'com.google.android.gms:play-services-base:8.4.0'

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

Is there anything that i have missed to implement please let me know if there

Answer

Remove:

mGoogleApiClient = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();

from onCreate() last line number, it overwrite object.
