如何讓圖標顯示推送通知消息

Question

如何讓我的圖標顯示在android中的推送通知消息旁邊。我有一個科爾多瓦應用程序，我看到iOS推送消息的圖標，但在Android上，我的推送消息旁邊有一個白色圓圈。

我有這個安裝在我的config.xml文件

<platform name="android"> 

     <icon src="splash/icon/android/icon-96-xhdpi.png" /> 
     <icon density="ldpi" src="splash/icon/android/icon-36-ldpi.png" /> 
     <icon density="mdpi" src="splash/icon/android/icon-48-mdpi.png" /> 
     <icon density="hdpi" src="splash/icon/android/icon-72-hdpi.png" /> 
     <icon density="xhdpi" src="splash/icon/android/icon-96-xhdpi.png" /> 
     <icon density="xxhdpi" src="splash/icon/android/icon-144-xxhdpi.png" /> 
     <icon density="xxxhdpi" src="splash/icon/android/icon-192-xxxhdpi.png" /> 

    </platform> 

感謝您的幫助

你好，你只需要調用從onMessageReceived（）這個方法在 MyFirebaseMessagingService你可以得到一個通知圖標而不是 白色圖標。希望這可能會幫助你。這是爲Android。像這樣： - Icon not displaying in notification: white square shown instead

private void sendNotification(String message, String mAction) { 
     int id = (int) System.currentTimeMillis(); 
     PendingIntent pendingIntent = null; 
     Intent intent = new Intent(this, SplashActivity.class); 
     intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | 
     Intent.FLAG_ACTIVITY_SINGLE_TOP); 
     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.mipmap.ic_launcher) 
       .setContentTitle(getString(R.string.app_name)) 
       .setContentText(message) 
       .setAutoCancel(true) 
       .setSound(defaultSoundUri) 
       .setContentIntent(pendingIntent); 
     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
      notificationBuilder.setSmallIcon(R.mipmap.ic_launcher); 
     } else { 
      notificationBuilder.setSmallIcon(R.mipmap.ic_launcher); 
     } 
     NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
     notificationManager.notify(id, notificationBuilder.build()); 
    }
