Класс RegistrationService для push, в чем проблема?

Создаю класс:

public class RegistrationService extends IntentService {
public RegistrationService() {
    super("RegistrationService");
}
String TAG = "MyLog";
@Override
protected void onHandleIntent(Intent intent) {
    Log.i(TAG, "11");
    InstanceID myID = InstanceID.getInstance(this);
    Log.i(TAG, "22");
    try {
        Log.i(TAG, "33");
        String registrationToken = myID.getToken(
                getString(R.string.gcm_defaultSenderId),
                GoogleCloudMessaging.INSTANCE_ID_SCOPE,
                null
        );
        Log.d("Registration Token", registrationToken);
        GcmPubSub subscription = GcmPubSub.getInstance(this);
        subscription.subscribe(registrationToken, "/topics/my_little_topic", null);
    } catch (IOException e) { e.printStackTrace(); }
}
}

На моменте

InstanceID myID = InstanceID.getInstance(this);

приложение падает. Где стоит поискать проблему?

Вот лог ошибки:
