谢谢。

// 在您的应用程序启动时调用
public void StartRegistrationNotification()
{
Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
registrationIntent.putExtra("sender", "....@gmail.com");
this.startService(registrationIntent);
}
// 在清单文件中进行更改

嗨，Samit，感谢你的帮助。但是我没有得到NotificationAlert类。在广播接收器中，我遇到了NotificationAlert类的错误。 - Chirag
嘿，通知类是您自己的定制代码。这意味着您需要自定义警报或通知... - SBJ
嗨，Samit，我遇到了以下错误。其中org.pushnotification.com是我的包名。 - Chirag
W/ActivityManager(2487): 权限拒绝：接收意图 { act=com.google.android.c2dm.intent.REGISTRATION cat=[org.pushnotification.com] (has extras) } 到 org.pushnotification.com 需要 org.pushnotification.com.permission.C2D_MESSAGE，因为发送者是 com.google.android.gsf (uid 10002)。 - Chirag

C2DM已被弃用，现已被Google Cloud Messaging for Android (GCM)所取代。
谷歌声明：
重要提示：自2012年6月26日起，C2DM已正式停用。这意味着C2DM已停止接受新用户和配额请求。C2DM将不再添加任何新功能。但是，使用C2DM的应用程序将继续工作。鼓励现有的C2DM开发人员迁移到名为Google Cloud Messaging for Android（GCM）的新版本。有关详细信息，请参见C2DM到GCM迁移文档。开发人员必须使用GCM进行新开发。
有GCM演示应用程序教程，也有从C2DM迁移的教程。
