Eu tenho um problema com um callbacks no serviço remoto, depois de registrar uma rotação de retorno de chamada causar um vazamento de atividade. Você pode me dar alguma sugestão do que estou fazendo de errado?

IRemoteApi.aidl

import com.example.remoteservice.IRemoteListener;

    interface IRemoteApi{
        void addListener(IRemoteListener listener);
        void removeListener(IRemoteListener listener);
        void sendRequest(String msg);
    }

IRemoteListener.aidl

 interface IRemoteListener {
        void onMessage(String text);
    }

RemoteService.java

public class RemoteService extends Service {
    private static final String TAG = RemoteService.class.getSimpleName();

    final RemoteCallbackList<IRemoteListener> mCallbacks = new RemoteCallbackList<IRemoteListener>();

    @Override
    public void onCreate() {
        super.onCreate();
        Log.e(TAG, "Create service...");
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        mCallbacks.kill();
    }

    private void dumpMethod(String msg){
        if(msg.equals("OK")){

            final int N = mCallbacks.beginBroadcast();
            for (int i=0; i<N; i++) {
                try {
                    mCallbacks.getBroadcastItem(i).onMessage("Voila!");
                } catch (RemoteException e) {}
            }
            mCallbacks.finishBroadcast();
        }
    }

    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }



    private IRemoteApi.Stub mBinder = new IRemoteApi.Stub() {
        @Override
        public void addListener(IRemoteListener listener) throws RemoteException {
            if (listener != null) mCallbacks.register(listener);
        }

        @Override
        public void removeListener(IRemoteListener listener) throws RemoteException {
            if (listener != null) mCallbacks.unregister(listener);
        }

        @Override
        public void sendRequest(String msg) throws RemoteException {
                dumpMethod(msg);
        }


    };

}

MainActivity.java

public class MainActivity extends ActionBarActivity {
    private static final String TAG = MainActivity.class.getSimpleName();

    IRemoteApi mService;
    boolean isBound = false;


    private ServiceConnection mServiceConnection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            mService = IRemoteApi.Stub.asInterface(service);
            isBound = true;
            Log.e("merhold", "Bound to service");

            try {
                mService.addListener(serviceListener);

            } catch (RemoteException e) {
                e.printStackTrace();
            }
        }

        getApplicationContext().startService(new Intent(RemoteService.class.getName()));
        getApplicationContext().bindService(new Intent(RemoteService.class.getName()), mServiceConnection, Context.BIND_AUTO_CREATE);
    }

    @Override

        super.onDestroy();

        if(isBound){
            try {

                getApplicationContext().unbindService(mServiceConnection);
            } catch (RemoteException e) {
                e.printStackTrace();
            }
        }
    }
