Android推送之APNS 网站调用提供推送技术
APNS 网站 http://www.push-notification.org
APNS 是什么?
APNS (Android Push Notification Service) 是一种在 android 上轻松实现 push notification 的功能的解决方案.
只需申请一个 API Key, 经过简单的步骤即可实现 push notification 的功能.
特点:
快速集成:提供一种比C2DM更加快捷的使用方式,避免各种限制.
无需架设服务器:通过使用"云服务",减少额外服务器负担.
可以同时推送消息到网站页面,android 手机
耗电少,占用流量少.
操作步骤：
1. 下载 libaray: com_apns.jar
2.将com_apns.jar添加到工程
3.接收 push notification
4.启动 Push Notification Service
5.配置 AndroidManifest.xml
Activity类如下：
