我正在使用Android示例项目,如:http://developer.android.com/guide/google/gcm/demo.html

有人可以帮帮我吗?这个错误来自哪里?

我在Linux机器上使用Jetty并使用Apache Ant在Windows机器上将其编译为.war ...

在发送消息之前,您可以将以下代码放入doPost()方法中:

import com.google.android.gcm.server.*;

Sender sender = new Sender(myApiKey);
Message message = new Message.Builder().build();
MulticastResult result = sender.send(message, devices, 5);

发件人可能未获得Google正确授权。

Sender sender = new Sender(MY_KEY);

MY_KEY与您在Google注册的密钥相同吗?替换documentation page

上显示的API密钥

在文本编辑器中,编辑samples / gcm-demo-server / WebContent / WEB-INF / classes / api.key,并用上面获得的API密钥替换现有文本。
