Samsung Galaxy ace2中的GCM註冊錯誤，但在仿真器中工作

Question

我能夠在第一次在Samsung Galaxy ace2中運行我的應用程序。現在，我正在跟隨GCM註冊失敗的錯誤。我在模擬器中工作正常，但不在該設備中工作。以下是錯誤和GCMIntentService.java。

錯誤：

Answer 1

即誤差在Google's GCM docs定義如下：

public static final String ERROR_SERVICE_NOT_AVAILABLE

The device can't read the response, or there was a 500/503 from the server that can be retried later. The application should use exponential back off and retry.

所以看起來好像它可能是一個暫時的錯誤，我會再試幾次，看看會發生什麼。

而且屁股@ol_v_er提到你需要確保你的設備符合GCM要求在GCM docs上市：

• It requires devices running Android 2.2 or higher that also have the Google Play Store application installed, or or an emulator running Android 2.2 with Google APIs. However, you are not limited to deploying your Android applications through Google Play Store.
• It uses an existing connection for Google services. For pre-3.0 devices, this requires users to set up their Google account on their mobile devices. A Google account is not a requirement on devices running Android 4.0.4 or higher.

Answer 2

如果你因爲沒有reeason此消息SERVICE_NOT_AVAILABLE並沒有計算器的回答您解決問題可能會被讀取，因爲所需要的只是耐心。所以塞爾茜的答案爲我工作。

在我的應用程序正常工作後，它突然開始生成SERVICE_NOT_AVAILABLE消息並顯示註冊ID爲空。然後我嘗試了兩個不同的模擬器上的應用程序，它在兩者上都工作正常。

我嘗試了各種stackoverflow帖子中的所有建議都無濟於事。我整晚都在設備上運行應用程序，並用SERVICE_NOT_AVAILABLE消息填充了半個屏幕。

我卸載了應用程序並關閉了設備並退出睡覺。第二天早上，我打開安裝的連接並再次運行該應用程序，它完美地工作。

奇怪的是，該設備已註冊爲GCM服務器的新設備。我的應用程序服務器還添加了另一個設備。不幸的是，我的應用程序服務器是一個枯燥的骨頭，沒有持久性或日誌記錄，所以我無法進一步調查。

有沒有人遇到過這種現象？
