我想从我的服务器接收到我的 android 应用程序的推送通知。我正在使用来自 Google Cloud Messaging for Android Library extras/google/samples/ 的示例。我已经在谷歌上搜索了 3 天以寻求帮助，但没有希望：/。
我就是这样进行的：
你会在最后找到源代码
I-服务器部分：
1-我用块注释打开 gcm-demo-server\WebContent\WEB-INF\classes\api。我用我的 api 密钥改变了它
2-在 gcm-demo-server 目录的 shell 窗口中，我运行“ant war”
3-我将 dist\gcm-demo.war 文件复制到 tomcat\webapps
4-我在浏览器中使用这个 url localhost:8080/gcm-demo 打开服务器
II-App部分：
在 CommonUtilities.java 我更改了以下字段：
1- 静态最终字符串 SERVER_URL = "localhost:8080/gcm-demo/home";(我的服务器 url)
2- 静态最终字符串 SENDER_ID = "876836784656"; （我的项目编号）
之后我打开服务器。它显示“未注册设备”，然后我运行显示“设备已在服务器上注册”的应用程序，但是当我刷新服务器时，它显示“未注册设备”，但是我的服务器必须显示已注册的设备和一个发送按钮“推送通知” :cry: PLEAAAZ 帮助！
