C#推送安卓—极光推送

先到极光推送官网注册一个帐号：

https://www.jpush.cn/common/products

登录后创建应用输入应用名和包名（推送根据包名），创建成功后把appkey和secret复制到

        private readonly string ApiKey = ConfigurationManager.AppSettings["ApiKey"].ToString(); 
        private readonly string APIMasterSecret = ConfigurationManager.AppSettings["APIMasterSecret"].ToString(); 

推送代码：

receiver_type指定推送方式。3是别名，4是广播。

官方案例：http://docs.jpush.io/resources/#sdk_1

                int receiver_type = 3;//接收者类型。2、指定的 tag。3、指定的 alias。4、广播：对 app_key 下的所有用户推送消息。5、根据 RegistrationID 进行推送。当前只是 Android SDK r1.6.0 版本支持
