Firebase notifications when app is closed

Question

I have implemented Firebase notification in my Android application. When my app is running, notification is displayed with my custom layout, but when application is not running, the notification is displayed with the default layout. How can I change the notification layout to my layout when application is not running. Also, I store shared preferences to let user toggle notifications. But when app is not running the notification is displayed anyways. How can achieve that?

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    if(SettingsFragment.getReceiceNotification()){ //if user wants to receive notification

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    RemoteViews remoteViews = new RemoteViews(getPackageName(),R.layout.push_notification_layout);

    remoteViews.setImageViewResource(R.id.push_notif_icon,R.mipmap.ic_bird_black);

    Intent intent = new Intent(this,MainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT);


    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
    notificationBuilder.setContent(remoteViews);
    notificationBuilder.setContentTitle("Radyo Türkkuşu");
    notificationBuilder.setContentText(remoteMessage.getNotification().getBody());

    notificationBuilder.setAutoCancel(true);
    notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
    notificationBuilder.setContentIntent(pendingIntent);
    remoteViews.setTextViewText(R.id.push_title, "Radyo Türkkuşu");
    remoteViews.setTextViewText(R.id.push_context, remoteMessage.getNotification().getBody());
    //notificationBuilder.setLights (ContextCompat.getColor(MainActivity.context, R.color.pushColor), 5000, 5000);
    notificationManager.notify(0,notificationBuilder.build());
    }

}

Your problem is you using it with notification tray.

See this link

Messages with both notification and data payload, both background and foreground. In this case, the notification is delivered to the device’s system tray, and the data payload is delivered in the extras of the intent of your launcher Activity.

If you using {data:"something"}(data-message) with {notification:"something"}(display-message) while your app is in background the data payload will delivered to extras of the intent but not to the onMessageReceived() method.I assume you implement your code for showing notification, so when your app is in foreground onMessageReceived() is trigger and it display the desire notification you want but when it is not onMessageReceived() no get trigger instead android system will handle it with your notification payload. You just have remove {notification:"something"}(display-message/notification tray) from your server side code to always ensure onMessageReceived().

For anyone keep mention onMessageReceived() will always trigger no matter wether it is not foreground or background please visit this link

There are two types of FCM messages

1. Notification message
2. Data message

Messages which get sent from Firebase console are Notification message. In order to get message in onMessageReceived() use Data Message. Use below code at server side to send Data Notification message

{
   "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
   "data" : {
     "Nick" : "Mario",
     "body" : "great match!",
     "Room" : "PortugalVSDenmark"
   },
 }
