谷歌云消息传递错误：无法实例化接收器

Question

我已经使用 Google Play 服务按照关于新 GCM 的 google 指南进行操作，经过数小时的开发后，我设法在 GCM 服务器上注册了我的设备，以获取 REGISTER_ID 并创建一个正确发送发布请求的 php 脚本。

坏消息是我没有收到推送通知，当我运行我的应用程序时，logcat 显示此错误：

这是我的清单（我已经省略了代码中不必要的部分）：

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17"
    />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

<permission android:name="com.baruckis.SlidingMenuImplementation.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />
<uses-permission android:name="com.baruckis.SlidingMenuImplementation.permission.C2D_MESSAGE" />

<!-- This app has permission to register and receive data message. -->
<uses-permission
    android:name="com.google.android.c2dm.permission.RECEIVE" />

<application

               [...]

<receiver
        android:name="com.baruckis.SlidingMenuImplementation.GcmBroadcastReceiver"
        android:enabled="true"
        android:exported="true"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <!-- Receives the actual messages. -->
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.baruckis.SlidingMenuImplementation" />
        </intent-filter>
</receiver>

<service android:name="com.baruckis.SlidingMenuImplementation.GcmIntentService" />
<meta-data android:name="com.google.android.gms.version" android:value="4030500" />
    </application>

最后这是我的 GcmBroadcastReceiver 代码：

package com.baruckis.SlidingMenuImplementation;

import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.support.v4.content.WakefulBroadcastReceiver;

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    // Explicitly specify that GcmIntentService will handle the intent.
    ComponentName comp = new ComponentName(context.getPackageName(),
            GcmIntentService.class.getName());
    // Start the service, keeping the device awake while it is launching.
    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);
   }
}

谢谢大家！ :)

尝试扩展提供的：com.google.android.gcm.GCMBroadcastReceiver

public class MyGCMBroadcastReceiver extends com.google.android.gcm.GCMBroadcastReceiver {
    protected String getGCMIntentServiceClassName(Context context) {
        return GCMIntentService.class.getName();
    }
}
