从我的ASP.NET网络服务和使用我的GCM浏览器API密钥，我可以成功发送GCM推送通知，获得以下成功响应：
{ “multicast_id”：4623804699821154941， “成功”：1， “失败”：0， “canonical_ids”：0 “结果”：[{ “MESSAGE_ID”： “0：1393876717064721％59cd098ff9fd7ecd”}
两个问题：
1）即使多次“发送”和浏览器刷新控制台页面，Google Developers Console也会显示0（零）次请求和0次错误。每次GCM推送通知都不应该改变计数？
2）我的Android设备未收到推送通知。
我的代码模仿： remote server returned an error: (401) unathorized in C# GCM response
传入的Android设备ID是从成功的Android设备注册中复制的。 我的服务器（网络服务）代码如下：

答案 0 :(得分：0)
GcmBroadcastReceiver和GcmIntentService不应该是您的活动类的内部类。它们应该是常规（顶级）课程。
当您在清单中将它们声明为.GcmBroadcastReceiver和.GcmIntentService时，意味着它们应位于com.MichaelResslerFineArt.eclipmessenger.GcmBroadcastReceiver和com.MichaelResslerFineArt.eclipmessenger.GcmIntentService，但是因为您将它们实现为内部类，它们实际上位于com.MichaelResslerFineArt.eclipmessenger.ProfileActivity.GcmBroadcastReceiver和com.MichaelResslerFineArt.eclipmessenger.ProfileActivity.GcmIntentService，因此当邮件到达您的设备时无法找到它们。
