Answer 1

I solved by adding this and lowering the play-service dependancy to 8.4.0 compile 'com.google.android.gms:play-services:8.4.0'

    @Override
protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(newBase);
    MultiDex.install(this);
}

and add the following to the manifest

android:name="android.support.multidex.MultiDexApplication"
