Изображение не отображается с текстом push-уведомления

Question

В моем случае, текстовое push-уведомление Firebase работает нормально, но изображение не отображается в push-уведомлении. Пожалуйста, скажите мне, что может быть причиной, а также, пожалуйста, исправьте мой код, потому что я новичок в Android Studio.

просто добавьте этот код в файл MyFirebaseMessagingService .. Преобразуйте изображение-уведомление в растровое изображение.

String channelId = getString(R.string.default_notification_channel_id);
    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
            new NotificationCompat.Builder(this, channelId)
                    .setSmallIcon(R.drawable.notification_icon)
                    .setLargeIcon(bitmap)
                    .setStyle(new NotificationCompat.BigPictureStyle()
                            .bigPicture(bitmap))
                    .setContentTitle(remoteMessage.getNotification().getTitle())
                    .setContentText(messageBody)
                    .setAutoCancel(true)
                    .setBadgeIconType(NotificationCompat.BADGE_ICON_SMALL)
                    .setSound(defaultSoundUri)
                    .setPriority(Notification.PRIORITY_HIGH)
                    .setVibrate(new long[]{1000, 1000, 1000, 1000, 1000})
                    .setContentIntent(pendingIntent);

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

    // Since android Oreo notification channel is needed.
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel channel = new NotificationChannel(channelId,
                getString(R.string.default_notification_channel_name),
                NotificationManager.IMPORTANCE_HIGH);
        channel.setVibrationPattern(new long[]{1000, 1000, 1000, 1000, 1000});
        channel.setShowBadge(true);
        channel.enableVibration(true);
        channel.enableLights(true);
        notificationManager.createNotificationChannel(channel);
    }

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