我杀死应用程序后未收到Firebase推送通知？

Question

1. FCM Notification is working fine when the app is foreground & background

2. Notification is not working when we kill the app?

My payload:

notification" : {
      "body" : "great match!",
      "title" : "Portugal vs. Denmark",
      }
"data" : {
     "Nick" : "Mario",
     "body" : "great match!",
   }

Answer 1

You always receive PUSH Notifications through FCM. But how notifications are received is different in both cases ie when app is in background and foreground. You have to check for it. Killing App will not effect it unless you stop service. If service is stopped, you won't receive notifications.

Second, if you are overriding onDataChange() and want to show notification whenever data changes then know that this function only executes when app is in foreground or not killed.
