android - 三星 Galaxy ace2 中的 GCM 注册错误但在模拟器中有效

Question

我能够在第一时间在 Samsung Galaxy ace2 中运行我的应用程序。现在，由于 GCM 注册失败，我收到以下错误。我在模拟器中工作正常，但在该设备中却不行。以下是错误和 GCMIntentService.java。

错误:

Answer 1

该错误在 Google's GCM docs 中定义如下:

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.

看来这可能是暂时的错误，我会再试几次，看看会发生什么。

@ol_v_er 还提到您需要确保您的设备满足 GCM docs 中列出的 GCM 要求。 :

• 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.
