Answer 1

Using latest Google Play services but was not working. For me this procedure is working:

1. Updated my Application class:

   public class App extends Application {
     @Override
     protected void attachBaseContext(Context base) {
       super.attachBaseContext(base);
       MultiDex.install(this);
    }
   }
   

2. Updated build.gradle file:

   defaultConfig {
       ...
       multiDexEnabled true
   }
   

3. Included dependencies:

   dependencies {
     compile 'com.android.support:multidex:1.0.0'
   }
