当我的应用程序被杀死或在后台运行时,我无法收到Firebase通知。
我签名了APK,但它不起作用。当我使用JSON发送数据通知时,logcat会显示以下错误:
以下是 Manifest 文件,导致这个 bug 的可能原因是什么? 谢谢提前。

以下是显示通知的代码:
public void onMessageReceived(RemoteMessage remoteMessage) {
Map<String, String> data = remoteMessage.getData();
//you can get your text message here.
String text= data.get("my_custom_key");
System.out.println(text);
notifies(text);
}
private void notifies(String body){
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(MyFirebaseMessagingService.this)
.setSmallIcon(android.R.drawable.ic_menu_help)
.setContentTitle("Congratulations!")
.setContentText(body);
Notification mNot= mBuilder.build();
NotificationManager mNotMan = (NotificationManager)
getSystemService(Context.NOTIFICATION_SERVICE);
mNotMan.notify(1,mNot);
