GCM 收不到消息

Question

您好，我正在创建一个项目，而且我是谷歌云消息传递的新手，我正在使用 Eclipse 学习 androidhive 的 GCM 教程。 API Key 和 SENDER ID 已设置。我成功获得了 regId 并将其插入到我的服务器端。现在的问题是从我的服务器接收到我的应用程序的消息不会出现。

{"multicast_id":6802394882982391839,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MismatchSenderId"}]}

我像在tutorial中一样放置发件人ID

            <!-- Receives the registration id. -->

设置此权限

 <permission
        android:name="com.jeffedward.pushnotifications.permission.C2D_MESSAGE"
        android:protectionLevel="signature"/>

<uses-permission android:name="android.permission.VIBRATE" />

并在您的代码中。 添加元数据

  <application
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name" >
            <!-- Register Activity -->
         <meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version"/>
       </application>
