//传入notifycation对象的作用是，当将服务设为前台服务后，会在状态栏显示一条通知
public void showCXBRunning() {
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        Notification builder = new Notification.Builder(this).setTicker("").setSmallIcon(R.drawable.ic_launcher).build();
        //id 不能为0
        startForeground(1, builder);
    }
