如何解决谷歌云信息登记错误：SERVICE_NOT_AVAILABLE？

I encountered a strange problem - I've been using GCM in my application for quite a long time and everything works perfectly. However, before a release to Google Play I changed my application package name from com.android.testapp to com.android.recognition and after this GCM stopped working. At first I got en error GCM sender id not set on constructor and fixed it by overriding getSenderIds(Context context), but now I can't get a registration ID. Here are the messages from logcat:

我该如何解决这个问题？当我切换到一个新的软件包我改变了一切，在清单文件到新的软件包：

How can I fix this? When I switched to a new package I changed everything in the manifest file to the new package:

<receiver
        android:name="com.google.android.gcm.GCMBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <category android:name="com.android.recognition" />
        </intent-filter>
    </receiver>

那么，什么是这背后的问题？可以重命名的应用程序包导致此还是有其他原因？

So what is the problem behind this? Can renaming the application package cause this or is there another reason?

推荐答案

本 SERVICE_NOT_AVAILABLE 错误说 GCM服务是不是在当前可用的。等待并尝试在一段时间后。

This SERVICE_NOT_AVAILABLE error says that GCM Service is not available in current. Wait and try after some time.

这会发生很多的时间（如我的经验），所以不用担心。

This happens many time (As my experience), so don't worry about it.

请参阅GCM库的 GCMConstants 类。

See the GCMConstants class of GCM Lib.

/**
     * 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.
     */
    public static final String ERROR_SERVICE_NOT_AVAILABLE =
            "SERVICE_NOT_AVAILABLE";
