当应用程序在前台时发送Firebase推送通知时，应用程序崩溃（仅在棉花糖（6.0.1）上），但在后台运行时工作正常

Question

Here is the code for the Firebase Messaging service:

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);

To show notification in foreground:

    private void showNotification(String title, String body) {
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        String NOTIFICATION_CHANNEL_ID = "com.shijan.qrscannerict.test";

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);

        notificationBuilder.setAutoCancel(true)
                .setDefaults(Notification.DEFAULT_ALL)
                .setWhen(System.currentTimeMillis())
                .setSmallIcon(R.drawable.ict_logo)
                .setContentTitle(title)
                .setContentText(body)
                .setContentInfo("Info");

        notificationManager.notify(new Random().nextInt(), notificationBuilder.build());
    }

The issue is fixed. The problem was that the app(Marshmallow) was not being able to extract the notification icon that I set. The app worked when I created a new image asset for the notification icon in the res directory.
