GCM 错误服务不可用

我在注册时遇到问题 GCM 服务器，我的日志中显示一条消息：服务不可用。我尝试了几种选择，但没有得到好的结果：

已经启用google_play_service的依赖， 已经检查时钟时间、巴西利亚设置的时区， 已经检查了我所知道的一切

下面是我的代码。

}

1.确保类 GetRegisterGCM() 在包 br.com.clientechattcc 中具有方法 serviceGCM.getRegistrationId() 而不是在 br.com.clientechattcc.asynctask 中；

2.卸载手机上的应用程序。

3.清理并运行项目。

4.这就是作品！
