Firebase通知和數據

Question

我正在使用Firebase雲消息傳遞API創建應用程序...我能夠將通知和數據從服務器發送到我的客戶端應用程序。 但問題是當應用程序打開時，數據出現時通知不會觸發（我的意思是我登錄了它）這不是問題。但是，當應用程序關閉時，會收到通知，而我單擊通知時，活動已打開，而我無法查看日誌數據。我需要將數據更新到一個TextView ..

我MyFirebaseMessagingService：

public void onMessageReceived(RemoteMessage remoteMessage) { 
     // TODO: Handle FCM messages here. 
     // If the application is in the foreground handle both data and notification messages here. 
     // Also if you intend on generating your own notifications as a result of a received FCM 
     // message, here is where that should be initiated. 
     Log.d(TAG, "From: " + remoteMessage.getFrom()); 
     Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody()); 
     Log.e("FROM", "From: " + remoteMessage.getFrom()); 
     String data = remoteMessage.getData().get("message"); 
     Log.e("KOIII", "Notification Message Body: " + remoteMessage.getNotification().getBody()); 
     // showNotificationS(remoteMessage.getNotification().getBody(),2); 
     if(data.equals("true")){ 
      Log.e("DATA", "SUCCESS"); 
      // Fragment1.getInstace().updateTheTextView(data, data, data); 
     } 
    } 

我的清單：

<activity 
      android:name=".SplashScreen" 
      android:label="@string/app_name" 
      android:launchMode="singleInstance"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
     <activity 
      android:name=".myHome" 
      android:label="@string/app_name"> 
     </activity> 
<service android:name=".MyFirebaseMessagingService"> 
      <intent-filter> 
       <action android:name="com.google.firebase.MESSAGING_EVENT"/> 
      </intent-filter> 
     </service> 
     <service android:name=".FirebaseIDService"> 
      <intent-filter> 
       <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/> 
      </intent-filter> 
     </service>

FCM將不會顯示通知，如果你的應用程序是在前臺，所以你必須手動顯示如下： -

@Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 
     // TODO(developer): Handle FCM messages here. 
     // If the application is in the foreground handle both data and notification messages here. 
     // Also if you intend on generating your own notifications as a result of a received FCM 
     // message, here is where that should be initiated. See sendNotification method below. 
     Log.d(TAG, "From: " + remoteMessage.getFrom()); 
     Log.d(TAG, "From: " + remoteMessage.getData().get("message")); 
//  Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody()); 
     sendNotification(remoteMessage.getData().get("message")); 
    } 
    // [END receive_message] 

    /** 
    * Create and show a simple notification containing the received FCM message. 
    * 
    * @param messageBody FCM message body received. 
    */ 
    private void sendNotification(String messageBody) { 
     Intent intent = new Intent(this, MarketActivity.class); 
//  intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, 
       PendingIntent.FLAG_ONE_SHOT); 

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

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

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

當您發送帶有da的通知消息有效載荷（通知和數據），並且應用程序在後臺，您可以從用戶點擊通知後啓動的意向附加項中檢索數據。

從它啓動時通報挖掘在MainActivity的FCM sample：

if (getIntent().getExtras() != null) { 
    for (String key : getIntent().getExtras().keySet()) { 
     String value = getIntent().getExtras().getString(key); 
     Log.d(TAG, "Key: " + key + " Value: " + value); 
    } 
}
