关于Android o+ 隐藏通知栏

[YUI]

网上查了很久，结果都是说前台服务不可以隐藏。我借鉴了该库的解决方式。但是并没有效果，这是我的代码，希望可以给个思路，谢谢了：）。

 private void startForeground() {
        if (KeepLive.sForegroundNotification != null) {
            Intent intent = new Intent(getApplicationContext(), NotificationClickReceiver.class);
            intent.setAction(NotificationClickReceiver.ACTION_CLICK_NOTIFICATION);
            final Notification notification = NotificationUtils.getNotification(this, KeepLive.sForegroundNotification.getTitle(), KeepLive.sForegroundNotification.getDescription(), KeepLive.sForegroundNotification.getIconRes(), intent);
            //隐藏通知栏
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                final NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                manager.notify(KEY_NOTIFICATION_ID, notification);
                startForeground(KEY_NOTIFICATION_ID, notification);
                if (manager.getNotificationChannel(notification.getChannelId()) != null) {
                    mHandler.post(new Runnable() {
                        @Override
                        public void run() {
                            manager.deleteNotificationChannel(notification.getChannelId());
                        }
                    });
                }
            }else {
                NotificationManagerCompat managerCompat = NotificationManagerCompat.from(this);
                managerCompat.notify(KEY_NOTIFICATION_ID,notification);
                startForeground(KEY_NOTIFICATION_ID,notification);
            }
        }
    }
