当 App 不在前台或不在前台时，Remoteview 显示系统通知运行而不是自定义通知

Question

首先，让我告诉你到目前为止我做了什么。我进行了很多搜索，包括

Also, I have referred GitHub and lots of articles but none of these worked for me so that is the reason I am posting this question, so please do not mark this as duplicate.

当应用程序处于运行时它工作正常，但当应用程序处于后台时它会显示系统通知。

我们需要添加 custom_notification_layout 对清单的引用吗？（是否有任何 meta tag 或其他内容？）

This is MyFireBaseMessagingService.java class

public class MyFireBaseMessagingServiceTmp extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        JSONObject jsonObject = new JSONObject(remoteMessage.getData());
        String title = jsonObject.optString("title");
        String message = jsonObject.optString("message");

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        if (Build.VERSION.SDK_INT >= 26) {
            NotificationChannel channel = new NotificationChannel("my_notifications", "My notifications", NotificationManager.IMPORTANCE_DEFAULT);
            notificationManager.createNotificationChannel(channel);
        }
        RemoteViews remoteViews;
        if (title == "BIG BANG") {
            remoteViews = new RemoteViews(getPackageName(), R.layout.layout_remainder_with_buttons);
        } else {
            remoteViews = new RemoteViews(getPackageName(), R.layout.layout_remainder_no_buttons);
        }
        remoteViews.setTextViewText(R.id.txtTitle, title);
        remoteViews.setTextViewText(R.id.txtMsg, message);

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, "my_notifications");
        notificationBuilder.setAutoCancel(true);
        notificationBuilder.setCustomBigContentView(remoteViews);
        {
            Intent intentGotIt = new Intent("ACTION_GOT_IT");
            PendingIntent pendingIntentGotIt = PendingIntent.getBroadcast(this, 0, intentGotIt, PendingIntent.FLAG_ONE_SHOT);
            remoteViews.setOnClickPendingIntent(R.id.btnGotIt, pendingIntentGotIt);
        }
        {
            Intent intentSnooze = new Intent("ACTION_SNOOZE");
            PendingIntent pendingIntentSnooze = PendingIntent.getBroadcast(this, 0, intentSnooze, PendingIntent.FLAG_ONE_SHOT);
            remoteViews.setOnClickPendingIntent(R.id.btnSnooze, pendingIntentSnooze);
        }
        notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
        notificationBuilder.setPriority(Notification.PRIORITY_HIGH);
        notificationBuilder.setAutoCancel(true);
        Bitmap icon = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
        notificationBuilder.setLargeIcon(icon);
        Notification notification = notificationBuilder.build();
        notification.sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        notification.vibrate = new long[]{0, 400, 200, 400};
        notificationManager.notify(1000, notification);
    }
}

Answer 1

From ServerSide

请确保 "You are NOT sending "notification" 字段在 "notification payload"如果您要发送？ 那么 请从您的服务器请求中删除 notification 字段并发送唯一的数据 .

因为当您的应用程序在后台运行时，Android 将NOT 执行onMessageReceived 并且系统将接管该通知并显示"Normal Notification".

因此，在您的通知负载中仅发送“data”。同时在您的通知负载中添加 {"priority": "high"}。

Here is the example for server response

{
  "to": "your_fcm_token",
  "priority": "high",
  "data":{
    "title": "your_title",
    "msg": "your_message",
    "other_info": "extra_info"
  }
}

希望这会有所帮助:)
