活动被终止时未调用MyFirebaseMessagingService

Question

当应用程序处于活动状态时，所有操作都正常运行，但当没有任何活动运行时，我仍然通过firebase notification获得一个带有app_name和Body的通知，并打开MainActivity。
这是我的MyFirebaseMessagingService类：-
我看到了一个类似的问题，但对我的情况没有帮助。

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    if(remoteMessage.getNotification()!=null){
        if(DictionarySscWords.send_notifications) { //tried removing this condition but same result.
            sendnoti(remoteMessage.getNotification().getBody());
        }
    }
}

private void sendnoti(String body) {
   Intent i1=new Intent(this,MainActivity.class);
    i1.putExtra("word", body);
    i1.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pi=PendingIntent.getActivity(this,0,i1,PendingIntent.FLAG_CANCEL_CURRENT);
    Uri ns=RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder nb=new NotificationCompat.Builder(this).setSmallIcon(R.drawable.heart)
            .setContentTitle("Word Of the Day")
            .setContentText(body).setSmallIcon(R.drawable.heart)
            .setAutoCancel(true)
            .setSound(ns)
            .setContentIntent(pi);
    NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0,nb.build());
}

}

正如它在Firebase文档中所说：

当应用程序处于后台时，通知消息会传递到通知托盘。对于前台应用程序,消息由以下回调处理：

DidReceiverEmoteNotification：在iOS上，Android上的OnMessageReceived（）。数据包中的通知键包含通知。

{
    "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification" : {
      "body" : "great match!",
      "title" : "Portugal vs. Denmark",
      "icon" : "myicon"
    }
  }

{
   "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
   "data" : {
     "Nick" : "Mario",
     "body" : "great match!",
     "Room" : "PortugalVSDenmark"
   },
 }
