從Appengine發送gcm push到android

我能夠從android設備註冊到appengine 一旦我註冊了appengine，我就得到了android應用上的registrationId。使用registrationId我試圖從appengine服務器發送消息到android應用程序。從Appengine發送gcm push到android

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

我已經將上面的代碼嵌入到http post方法中。

，但我得到以下錯誤：

誰能幫我解決這個問題。

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

多個Android設備：

我已經做如下修改代碼

單一Android設備解決了該問題

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

然而通知轉到Android設備從Appengine，但我仍然想知道如何將消息發送到Android設備以及通知。

你好，在這裏你提到MulticastResult結果= sender.send（消息，registrationIds的名單，5）; 所以，registrationIds列表是列表？ – Dev 2015-01-19 20:15:31

您應該捕獲GCMIntent服務的推送意向onReceiveMessage，並使用push intent的extras（getExtras（））捆綁包創建通知。

按照本指南：http://developer.android.com/guide/topics/ui/notifiers/notifications.html
