求大神帮忙看看，关于android service

[bagwell909]

用mqtt做消息推送，网上找了一个AndroidPushNotificationsDemo，在sdkversion 22以下都能运行，但我程序本身是24版本的，我把这个demo改到24，其中setLatestEventInfo不能使用，就改用Notification.Builder来创建 notification 实例，但是用不了，求大神帮忙看看这是什么问题

原来是这样的 Notification n = new Notification(); n.flags |= Notification.FLAG_SHOW_LIGHTS; n.flags |= Notification.FLAG_AUTO_CANCEL; n.defaults = Notification.DEFAULT_ALL; n.icon = com.tokudu.demo.R.drawable.icon; n.when = System.currentTimeMillis(); // Simply open the parent activity PendingIntent pi = PendingIntent.getActivity(this, 0, new Intent(this, PushActivity.class), 0); // Change the name of the notification here n.setLatestEventInfo(this, NOTIF_TITLE, text, pi); mNotifMan.notify(NOTIF_CONNECTED++, n); 我是这样改的 Notification.Builder builder = new Notification.Builder(this); builder.setSmallIcon(R.drawable.icon); //设置图标 builder.setTicker("显示第一个通知"); builder.setContentTitle(NOTIF_TITLE); //设置标题 builder.setContentText(text); //消息内容 builder.setWhen(System.currentTimeMillis()); //发送时间 builder.setDefaults(Notification.DEFAULT_ALL); //设置默认的提示音，振动方式，灯光 builder.setAutoCancel(true);//打开程序后图标消失 PendingIntent pi = PendingIntent.getActivity(this, 0, new Intent(this, PushActivity.class), 0); builder1.setContentIntent(pi); Notification n = builder.build(); mNotifMan.notify(NOTIF_CONNECTED++, n); 不知道有没有什么不对的地方 拜托大神帮忙看看啊，感谢各位
