Android Threads and Services But Wait There's More! Messengers and Handlers: Activity

Not Recognizing Inner Class

Bummer: Create an inner Handler class just like we did with GeolocationService.

Clearly I have done this...I can't get past this message in any way.

MainActivity.java 
// some methods omitted
public class MainActivity extends Activity {
    Boolean isBound = false;
    Messenger mServiceMessenger;
    Messenger mActivityMessenger = new Messenger(new InnerHandler(this));

    ServiceConnection mServiceConnection = new ServiceConnection() {
      @Override  
      public void onServiceConnected(ComponentName name, IBinder binder) {
        isBound = true;
        mServiceMessenger = new Messenger(binder);
      }

      @Override
      public void onServiceDisconnected(ComponentName name) {
        isBound = false;
      }
    };

    class InnerHandler extends Handler {
      private MainActivity mMainActivity;

      public InnerHandler(MainActivity mainActivity) {
          mMainActivity = mainActivity;
      }

      @Override
      public void handleMessage(Message msg) {
        super.handleMessage(msg);
      }

    } 
}
GeolocationService.java 
// some methods omitted
public class GeolocationService extends Service {
    int mLatitude;
    int mLongitude;
    Messenger mMessenger = new Messenger(new LocationHandler());

    @Override
    public IBinder onBind(Intent intent) {
      return mMessenger.getBinder();
    }

   class LocationHandler extends Handler {
      @Override
      public void handleMessage(Message msg) {
        mLatitude = getLatitude();
        mLongitude = getLongitude();
      }
    }
}
Difficulty.java 
  public class Difficulty {
    public static Boolean HARDMODE = false;    
  }
