我能够第一次在三星 Galaxy ace2 中运行我的应用程序。现在我收到以下错误，因为 GCM 注册失败。我在模拟器中工作正常，但在那个设备中不行。以下是错误和GCMIntentService.java。

错误：

该错误在Google 的 GCM 文档中定义如下：

公共静态最终字符串 ERROR_SERVICE_NOT_AVAILABLE

设备无法读取响应，或者来自服务器的 500/503 可以稍后重试。应用程序应使用指数退避并重试。

所以看起来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 ass @ol_v_er 提到您需要确保您的设备符合GCM 文档中列出的 GCM 要求：

  • 它要求运行 Android 2.2 或更高版本的设备也安装了 Google Play Store 应用程序，或者运行 Android 2.2 和 Google API 的模拟器。但是，您不仅限于通过 Google Play 商店部署您的 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，这要求用户在其移动设备上设置其 Google 帐户。运行 Android 4.0.4 或更高版本的设备不需要 Google 帐户。

如果您无缘无故地收到此消息 SERVICE_NOT_AVAILABLE 并且 stackoverflow 的答案都没有解决您的问题，请继续阅读，因为可能只需要耐心。所以 selsine 的回答对我有用。

After my app working fine on a nexus it suddenly started generating SERVICE_NOT_AVAILABLE messages and showing the registration id as null. I then tried the app on two different emulators and it worked fine on both.

I tried all the suggestions in the various stackoverflow postings to no avail. I left the app running on the device all evening and filled half a screen with SERVICE_NOT_AVAILABLE messages.

I uninstalled the app and switched off the device and retired to bed. The following morning, I switched on the nexus installed and ran the app again and it worked perfectly.

The strange thing is that the device was registered as a new one with the GCM server. My application server also notched up another device added. Unfortunately, my application server is a bare bones one, no persistence or logging so I'm unable to investigate further.

Has anyone else experienced this phenomenon?
