我在Android应用程序中使用FirebaseMessaging进行即时消息传递。FirebaseMessaging Android有些消息丢失

对于从服务器到设备Android的消息,不会丢失消息。

但是从移动到服务器一些消息丢失...

服务器接收ACK消息,但在其他方向(移动到服务器)移动不接收ACK。

其结果是大约30%的消息丢失。如果我快速发送多条消息,会有更多的损失(40-60%)。如果我缓慢地发送多个消息,则有10%的消息丢失...

当我将消息发送到服务器时,我注意到在我的FirebaseMessagingService中,方法“onMessageSent”被10个消息模糊地调用。这是正常的吗? 为什么 “onMessageSent” 不是一次,只要消息被发送称为...

public class MyFirebaseMessagingService extends FirebaseMessagingService { 

private static final String TAG = "MyFirebaseMsgService"; 
/** constante pour renvoyer la position GPS */ 
public static final String BROADCAST_FIREBASE_FILTER= "android.intent.action.MY_APP_FIREBASE"; 

private DatabaseHelper helper; 

@Override 
public void onCreate() { 
    super.onCreate(); 
} 

/** 
* Called when message is received. 
* 
* @param remoteMessage Object representing the message received from Firebase Cloud Messaging. 
*/ 
// [START receive_message] 
@Override 
public void onMessageReceived(RemoteMessage remoteMessage) { 
    Notification method below.  
    DebugLog.logw(TAG,"MESSAGE RECEIVED"); 
    String clickAction = remoteMessage.getNotification().getClickAction();   
    [..] 

} 
// [END receive_message] 

/** 
* Create and show a simple notification containing the received FCM message. 
* 
* @param messageBody FCM message body received. 
*/ 
private void sendNotification(String title, String messageBody,Intent intent2) { 

    intent2.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent2, 
      PendingIntent.FLAG_ONE_SHOT); 

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
      .setSmallIcon(R.mipmap.ic_launcher) 
      .setContentTitle(title) 
      .setContentText(messageBody) 
      .setAutoCancel(true) 
      .setSound(defaultSoundUri) 
      .setContentIntent(pendingIntent); 

    NotificationManager notificationManager = 
      (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build()); 

} 

@Override 
public void onDeletedMessages() { 
    super.onDeletedMessages(); 
    DebugLog.logi(TAG, "onDeletedMessages"); 
} 

@Override 
public void onMessageSent(String s) { 
    super.onMessageSent(s); 
    DebugLog.logi(TAG, "onMessageSent = " + s); 
} 

@Override 
public void onSendError(String s, Exception e) { 
    super.onSendError(s, e); 
    DebugLog.logi(TAG, "onSendError = " + s); 
} 

}

我在我的FragmentMessaging方法发送消息:

public void sendMessage(Message msg){ 
    DebugLog.logd("FragmentMessagerie","sendMessage msg = " + msg.getMsg()); 
    if(textMessage.getText().length()>0) { 
     final Message message = msg;   

     AtomicInteger atomicInteger = new AtomicInteger(); 
     FirebaseMessaging fm = FirebaseMessaging.getInstance(); 

     RemoteMessage rm = new RemoteMessage.Builder(senderID) 
       .setMessageId("myApp_" + atomicInteger.incrementAndGet() + System.currentTimeMillis()) 
       .addData("action", "chat") 
       .addData("destinataire", String.valueOf(contact.getId())) 
       .addData("emetteur",username) 
       .addData("texte",msg.getMsg()) 
       .setTtl(0) 
       .build();      
     fm.send(rm); // appel à fireBase pour l'envoi du message 
     [..] 

     textMessage.setText(""); 
    } else { 
     [..] 
    } 
} 

}

我的问题是:

当发送消息(firebaseMessaging.send(remoteMessage))Firebase应该处理向服务器发送消息。

Android是否将消息错误地发送到Firebase?

还是Firebase将消息严重地发送到我的服务器?

在服务器上,我收到发送给手机的ACK消息。

在我的设备Android上,我没有收到ACK消息,当发送10条消息时,只有方法“onMessageSent”被调用了10次......这是正常的吗?

如何才能收到ACK消息设备Android到服务器?从我的设备?

在此先感谢您的帮助!

它清楚地在FCM documentation中说,响应是成批的。

为了优化网络使用率,FCM批次响应onMessageSent和 onSendError,因此确认可以不会立即对每条消息。
