        Notification notification = new Notification.Builder(this).setContentTitle(decodedMsg).

                setContentText(decodedMsg).setSmallIcon(R.drawable.appicon).build();

        RemoteViews bigContentView = new RemoteViews(context.getPackageName(),

                R.layout.custom_notification);

        bigContentView.setImageViewBitmap(R.id.image, bitmap);

        bigContentView.setTextViewText(R.id.title, decodedMsg);

        bigContentView.setTextViewText(R.id.time, PlusTimeFormatter.doIt());

        //아래 코드가 없으면 notification이 크게 표시안됨

        notification.priority = Notification.PRIORITY_MAX;

        notification.bigContentView = bigContentView;

                FWConstants.BANNER_URL_HEAD + detailPageUrl);

        PendingIntent contentIntent = PendingIntent.getActivity(context, 0,

                notificationIntent, 0);
