使用 GoogleCloudMessaging 的 Android gcm 客户端

Question

我正在使用 gcm 描述的新方法 here使用 GoogleCloudMessaging 类。但是 10 次中有 9 次出现 SERVICE_NOT_AVAILABLE 错误。只有一次它注册了一个设备。

07-01 14:24:55.907    2074-2090/com.deveyes.carrefour          W/System.err:                   java.io.IOException: SERVICE_NOT_AVAILABLE

07-01 14:24:56.037    2074-2090/com.deveyes.carrefour          W/System.err: at com.google.android.gms.gcm.GoogleCloudMessaging.register(Unknown Source)

我的 Activity 中的代码如下:

 .....
     gcmRegId = gcm.register(CarrefourConfig.GCM_SENDER_ID);   
 .....                                                       

后来才知道需要用到Automatic retry。我读过this但这份文件似乎很旧。与新方法一样，我们不再使用 IntentService。还是我们？在 BroadcastReciever 中，我可以获取消息并通知用户。

我做错了什么？

问题来了:

您应该在下面的所有 3 个地方使用相同的包名称，但在某些情况下您使用 com.deveyes.carrefour.android 而在某些情况下使用 com.deveyes.carrefour其他情况。

<permission android:name="com.deveyes.carrefour.android.permission.C2D_MESSAGE"
            android:protectionLevel="signature" />
<uses-permission android:name="com.deveyes.carrefour.android.permission.C2D_MESSAGE" />
...
    <receiver
            android:name=".gcm.GCMBroadcastReceiver"
            android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.deveyes.carrefour" />
        </intent-filter>
    </receiver>

如果您的包名称是 com.deveyes.carrefour，请将 list 更改为:

<permission android:name="com.deveyes.carrefour.permission.C2D_MESSAGE"
            android:protectionLevel="signature" />
<uses-permission android:name="com.deveyes.carrefour.permission.C2D_MESSAGE" />
...
    <receiver
            android:name=".gcm.GCMBroadcastReceiver"
            android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.deveyes.carrefour" />
        </intent-filter>
    </receiver>
