我可以在第一次在Samsung Galaxy ace2中运行我的应用程序。现在我因未能进行GCM注册而遇到以下错误。我在模拟器中工作正常，但在该设备中没有。以下是错误GCMIntentService.java。

答案 0 :(得分：1)
该错误在Google's GCM docs中定义如下：
public static final String ERROR_SERVICE_NOT_AVAILABLE
设备无法读取响应，或者有500/503 可以在以后重试的服务器。应用程序应该使用 指数退避并重试。
所以好像这可能是一个暂时的错误，我会再试几次，看看会发生什么。
另外，@ ol_v_er提到您需要确保您的设备符合GCM docs中列出的GCM要求：
- 它要求运行Android 2.2或更高版本且安装了Google Play商店应用程序的设备，或运行带有Google API的Android 2.2的模拟器。但是，您不仅限于通过Google Play商店部署Android应用程序。
- 它使用现有的Google服务连接。对于3.0之前的设备，这需要用户在其移动设备上设置自己的Google帐户。运行Android 4.0.4或更高版本的设备不需要使用Google帐户。

如果您收到此消息SERVICE_NOT_AVAILABLE没有任何reeason并且没有任何stackoverflow答案解决您的问题，因为可能所需要的只是耐心。所以selsine的回答对我有用。
在我的应用程序在nexus上正常工作后，它突然开始生成SERVICE_NOT_AVAILABLE消息并将注册ID显示为null。然后我在两个不同的模拟器上尝试了应用程序，它在两者上运行良好。
我尝试了各种stackoverflow帖子中的所有建议都无济于事。我整晚都在设备上运行应用程序并使用SERVICE_NOT_AVAILABLE消息填充了半个屏幕。
我卸载了应用程序并关闭了设备并退休睡觉。第二天早上，我打开了安装的nexus并再次运行应用程序，它运行良好。
奇怪的是，该设备已通过GCM服务器注册为新设备。我的应用程序服务器还添加了另一个设备。不幸的是，我的应用程序服务器很简单，没有持久性或日志记录，所以我无法进一步调查。
还有其他人遇到过这种现象吗？
