GCM無法實例化接收器/ ClassNotFoundException

以下是我通過GCM向我的設備發送通知時所得到的結果。我到處搜索，我仍然無法弄清楚我做錯了什麼。

import android.support.v4.content.WakefulBroadcastReceiver;

public class NotificationsReceiver extends WakefulBroadcastReceiver 
{ 
    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     Log.i("GcmBroadcastReceiver", "receive message !"); 

     ComponentName comp = new ComponentName(context.getPackageName(), GcmMessageHandler.class.getName()); 
     startWakefulService(context, (intent.setComponent(comp))); 
     setResultCode(Activity.RESULT_OK); 
    } 
} 

請幫助。
