Android Firebase：华为p8推送通知app在后台时系统不显示？

Question

根据Firebase文档：

我的问题是，当应用程序在后台时，通知系统不显示通知。

我没有使用Firebase控制台，因为我无法将数据添加到通知负载中。所以我使用了RESTful客户机API，但还是同样的问题。

请求：

URL:https://fcm.googleapis.com/fcm/send
Method type: POST
Content-Type: application/json
Authorization : key=AAAAFi0N5KM....
Body:

    {
     "priority" : "high",
     "notification" : {
         "body" : "This week’s edition is now available.",
         "title" : "NewsMagazine.com",
         "icon" : "new",
         "click_action": "OPEN_ACTIVITY_1" ,
         "sound" : "mySound"

     },
     "data": {
         "title": "title " ,
         "body": "any vaslue " 
     },
     "registration_ids": ["fVNdKJsWtNQ:APA91bEJ...."]
}

   {
    "message_id": "0:1486655756341577%dc81f05ff9fd7ecd"
   }
  ]
 }

public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    sendNotification(remoteMessage.getData().get("title"),remoteMessage.getData().get("body"));
}

private void sendNotification(String messageTitle,String messageBody) {
    Intent intent = new Intent(this, SplashActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this,0 /* request code */, intent,PendingIntent.FLAG_UPDATE_CURRENT);

    long[] pattern = {500,500,500,500,500};

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.roshetta_logo_home)
            .setContentTitle(messageTitle)
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setVibrate(pattern)
            .setLights(Color.BLUE,1,1)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

  <service android:name=".Util.PushNotification.MyFirebaseMessagingService"
         >
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT"/>
        </intent-filter>

每次我们在华为手机上遇到问题，都是因为该应用程序不是“受保护的应用程序”。

1. 转到设置
2. 向下滚动并点击“高级设置”
3. 点击电池管理器
4. 查找受保护的应用程序并选择它
5. 查找您的应用程序，并将其设置为受保护
