Android Google云消息错误：无法实例化接收器

我使用google Play服务遵循google指南中关于新GCM的内容，经过数小时的开发，我成功地在GCM服务器上注册了我的设备，获得了register_ID，并创建了一个php脚本，该脚本可以正确地发送post请求

坏消息是，当我运行应用程序logcat时，我没有收到推送通知，显示以下错误：

这是我的清单（我省略了代码中不必要的部分）：

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();
    }
}

GcmBroadcastReceiver代码中的包行在哪里？更新代码，对不起，我忘记复制和粘贴了！我认为这不是一个可行的解决方案！我需要从Wakefull的接收器上延伸…好的。尝试使用：android:name=“.GcmBroadcastReceiver”代替android:name=“com.baruckis.slidingmenuiimplementation.GcmBroadcastReceiver”。我知道（根据经验），GCM库代码对接收方类相对于目标服务的位置做出了一些假设。试试看。他们的例子显示了在清单中注册为相对包名的接收者。你知道，我认为你应该试试我的第一个答案。如果查看来自GCMBroadcastReceiver的源代码，它将调用：GCMBaseIntentService.runIntentService（上下文、意图、类名）；这是一个静态例程，在启动服务之前获取唤醒锁。因此，您不需要WakefulBroadcastReceiver，因为唤醒锁是在onReceive返回之前获取的。这是我使用的，没有任何问题。

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);
   }
}

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