Android 无法生成通知FireBase

我收到通知，但它是由FireBase自动生成的。我无法设置自己的通知。我已尝试从onMessageReceived方法生成通知并设置标题，但随后它将停止显示通知。仅显示默认通知

public class FireBaseMessaging extends FirebaseMessagingService {
    private static final String TAG = "FCM Service";

    @TargetApi(Build.VERSION_CODES.JELLY_BEAN)
    @Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    Log.d("Msg", "Message received ["+remoteMessage+"]");

    // Create Notification
    Intent intent = new Intent(this, WebHandler.class);
    intent.putExtra("links","http://www.google.com");

    PendingIntent pendingIntent = PendingIntent.getActivity(this, 1410,
            intent, PendingIntent.FLAG_ONE_SHOT);

    NotificationCompat.Builder notificationBuilder = new
            NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_shopping_cart_white_24dp)
            .setContentTitle("Message")
            .setContentText(remoteMessage.getNotification().getBody())
            .setAutoCancel(true)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager)
                    getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(1410, notificationBuilder.build());
    }




}

你到底在做什么来发送它？当我收到通知时，我正在尝试构建自定义通知。出于测试目的，我使用上述代码生成了一个通知，但只显示firebase生成的默认通知，而不显示我的自定义通知
