Google Firebase通知会启动不同的活动

Question

我有一个Firebase通知，可以完美地发送到我的设备。出于某种原因，当我点击通知时，它会启动另一个Activity而不是我在我的方法onMessage中声明的Activity。我检查了所有可能的原因，但找不到问题。 当我点击通知时，我想将消息发送到另一个活动。

这是我的代码：

public class FireMsgService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);

    Log.d("Msg", "Message received ["+remoteMessage.getData().toString()+"]");
    String notificationMessage = remoteMessage.getNotification().getBody();
    String notificationTitle = "LendingSquare Alert!";
    int notificationIndex = 1410;

    String CHANNEL_ID = "my_channel_01";
    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this, CHANNEL_ID)
                    .setSmallIcon(R.drawable.logo)
                    .setContentTitle(notificationTitle)
                    .setContentText(notificationMessage);
    // Creates an explicit intent for an Activity in your app
    Intent resultIntent = new Intent(this, NotificationActivity.class);

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    // Adds the back stack for the Intent (but not the Intent itself)
    stackBuilder.addParentStack(NotificationActivity.class);
    // Adds the Intent that starts the Activity to the top of the stack
    stackBuilder.addNextIntent(resultIntent);
    PendingIntent resultPendingIntent =
            stackBuilder.getPendingIntent(
                    0,
                    PendingIntent.FLAG_UPDATE_CURRENT
            );
    mBuilder.setContentIntent(resultPendingIntent);
    NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    mNotificationManager.notify(notificationIndex, mBuilder.build());

}
}
