GCM:从不调用来自GCMIntentService的onMessage()

我正在我的应用程序中实现GCM (Google Cloud Messaging- PUSH Notifications)。我已经按照developer.android.com

中的GCM教程中的所有步骤进行了操作

我的应用程序的构建目标指向Goolge API 8 (Android 2.2 version)

我能够成功从GCM获取注册ID,并且我将此ID传递给我的应用服务器。因此注册步骤成功完成。

现在,当我的应用服务器向我的设备发送PUSH消息时,服务器将消息显示为SUCCESS=1 FAILURE=0, etc.,即服务器正在成功发送消息,但我的设备从未收到消息。

经过大量搜索后,我发现GCM在端口号5228,5229或5230上发送消息。

最初,我的设备和笔记本电脑仅限于某些网站,但后来我被授予了访问所有网站的所有权限,所以我猜这些端口号是为我的设备打开的。

所以我的问题是:我从未收到来自GCM的任何PUSH消息。我从未调用GCMIntenService类的onMessage()。可能是什么原因?

请参阅我的以下代码并相应地指导我:

我已在我的清单中声明了以下内容:

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="8" />

    <permission
        android:name="package.permission.C2D_MESSAGE"

    <!-- GCM connects to Google Services. -->
    <uses-permission android:name="android.permission.INTERNET" />

    <!-- GCM requires a Google account. -->
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />

    <!-- Keeps the processor from sleeping when a message is received. -->

                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

                <category android:name="packageName" />
            </intent-filter>
        </receiver>
        <receiver
            android:name=".ReceiveBroadcast"
            android:exported="false" >
            <intent-filter>
                <action android:name="GCM_RECEIVED_ACTION" />
            </intent-filter>
        </receiver>

        <service
            android:name=".GCMIntentService"
            />

        Toast.makeText(context, "PUSH Notification failed.", Toast.LENGTH_LONG)
                .show();
    }

    @Override
    protected boolean onRecoverableError(Context context, String errorId) {
        return super.onRecoverableError(context, errorId);
    }
}

如果重命名了包名,则应覆​​盖GCMBroadcastReceiver类child中的getGCMIntentServiceClassName()方法。示例here
