我能够从 android 设备注册到 appengine 一旦我向 appengine 注册，我就会在 android 应用程序上获得registrationId。使用registrationId我试图将消息从appengine服务器发送到android应用程序。

Sender sender = new Sender(App-Key);
Message message = new Message.Builder().addData("data", "hello client").build();
Result result = sender.send(message, registrationId , 5);

我已将上述代码嵌入到 http post 方法中。

但我收到以下错误：

Uncaught exception from servlet

您应该捕获 GCMIntent 服务的 onReceiveMessage 推送意图，并使用推送意图的附加 (getExtras()) 包创建通知。

遵循本指南：http: //developer.android.com/guide/topics/ui/notifiers/notifications.html

我已通过对代码进行以下更改来解决此问题

对于单个 android 设备：

Sender sender = new Sender(App-Key);
Message message = new Message.Builder().build();
Result result = sender.send(message, registrationId , 5);

对于多个安卓设备：

Sender sender = new Sender(App-Key);
Message message = new Message.Builder().build();
MulticastResult result = sender.send(message, list of registrationIds , 5);

然而，通知从 appengine 发送到 android 设备，但我仍然想知道如何将消息与通知一起发送到 android 设备。
