我在使用推送通知Firebase时遇到问题, 问题 : 应用程序图标在棉花糖及以上显示为白色,因此我创建了白色和透明的图标集,现在推送通知图标显示为我需要仅当应用程序位于前景<时/ strong>当用户收到通知且应用已关闭时,图标会显示为白色。

我的清单

<application
        android:name="com.xxxx"
        android:allowTaskReparenting="true"
        android:hardwareAccelerated="true"
        android:icon="@drawable/ic_xxxx"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:theme="@style/AppTheme">

通知代码:当我收到推送通知时

Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
            NotificationCompat.Builder notificationBuilder;
            if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                notificationBuilder = new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.xxxxxx)
                        .setColor(getResources().getColor(R.color.accent))
                        .setContentTitle(messageTitle)
                        .setContentText(messageBody)
                        .setAutoCancel(true)
                        .setSound(defaultSoundUri)
                        .setContentIntent(contentIntent);
            } else {
                notificationBuilder = new NotificationCompat.Builder(this)
                        .setSmallIcon(R.mipmap.ic_launcher)
                        .setContentTitle(messageTitle)
                        .setContentText(messageBody)
                        .setAutoCancel(true)
                        .setSound(defaultSoundUri)
                        .setContentIntent(contentIntent);
            }



            NotificationManager notificationManager =
                    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
            notificationManager.notify(count, notificationBuilder.build());
消息接收代码

 @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        //Displaying data in log
        //It is optional
        Log.d(TAG, "Notification Message TITLE: " + remoteMessage.getNotification().getTitle());
        Log.d(TAG, "Notification Message BODY: " + remoteMessage.getNotification().getBody());
        Log.d(TAG, "Notification Message DATA: " + remoteMessage.getData().toString());

        //Calling method to generate notification
        //remoteMessage.getNotification().getBody()
        sendNotification(remoteMessage.getNotification().getTitle(),
                remoteMessage.getNotification().getBody(), remoteMessage.getData());
    }

那里有两种类型的通知。

1。)使用默认参数

    String title = remoteMessage.getNotification().getTitle();
    String body = remoteMessage.getNotification().getBody();

服务器端代码:

{ "data": {
    "score": "5x1",
    "time": "15:10"
  },
  "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1..."
}

此类实施仅在应用程序处于打开状态或后台时才有效。您将收到通知消息(如您​​所说,将显示空白通知),但您无法从中获取任何数据。

2。)使用地图

   Map data =  remoteMessage.getData();

服务器端代码:

{
  "message":{
    "token" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification" : {
      "body" : "This is an FCM notification message!",
      "title" : "FCM Message",
      }
   }
}

即使在应用关闭后,这也会收到。它不会产生空白白色通知。

如果通知图标的问题为白色。尝试在清单

中添加此代码
<meta-data 
android:name="com.google.firebase.messaging.default_notification_icon" 
android:resource="@drawable/app_icon" />
