FCMが一部のメッセージング遅延を伴う信頼性の低いメッセージ

Question

私の問題は、サーバーから、Firebaseから取得したInstanceIDを持つ特定のクライアントにメッセージを送信しているときに、常にメッセージを受け取るとは限りません。 ほとんどの場合、私はメッセージを受け取ることさえできず、時にはアンドロイドデバイスに5〜10分後にメッセージが届きます。

public class MessagingService extends FirebaseMessagingService{ 

public static final String SERVICE_RESULT = "at.ideafactory.spotted.Firebase.REQUEST_PROCESSED"; 
public static final String SERVICE_MESSAGE = "at.ideafactory.spotted.Firebase.REQUEST_MSG"; 

private LocalBroadcastManager broadcastManager = LocalBroadcastManager.getInstance(this); 

@Override 
public void onMessageReceived(RemoteMessage remoteMessage){ 
    notifyMainActivity(remoteMessage.getData().get("obj_location")); 
} 


public void notifyMainActivity(String data){ 
    if(data != null && data.length() != 0 && !data.equals("")){ 
     Intent intent = new Intent(SERVICE_RESULT); 
     intent.putExtra(SERVICE_MESSAGE, data); 
     broadcastManager.sendBroadcast(intent); 
    } 
} 

} 

誰かが私の問題を助けてくれますか？ 通知が利用できるかどうかをデバイスで確認できるかどうか知りませんか？

種類よろしく

Answer 1

あなたはFirebase hereによって提供されているコードをテストし、あなたがメッセージを送信したときに通知を受け取るかどうかを確認してもらえますか？ このコードでFCMをテストしていたときに、すぐに通知を受け取りました。この問題は、サーバー側やアプリの他の部分にある可能性があります。

Answer 2

今私は、アプリケーションサーバーからFCMサービスに送信するJSONオブジェクトに「優先度」プロパティがあることに気付きました。

デフォルト：「優先順位」：「ノーマル」

私は今、私はデバイス上でリアルタイムに私のサーバーから送信されたメッセージを受信することができるよ、「高」に「優先」に設定しました。
