Android:GCM 推送通知从服务器端成功发送但未在客户端获取

Question

我正在从我的服务器端应用程序发送 GCM 推送通知，它显示成功，但我没有在我的设备上收到这些消息。我的 Google api key 和 Reg id 也是正确的，我在这里发布我的 android 代码。请检查并指出我在这段代码中做错了什么。

您没有在 mainfest 中添加服务。只需将其添加到 list 中

<!-- services -->
        <service android:name=".GCMNotificationIntentService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            </intent-filter>
        </service>

我认为它有效。
