唤醒广播接收者无法解析为类型

我的项目显示错误消息.我抬起头来，寻找我能想到的所有可能的原因。我已经设定了和的路径。即使我的mapView也可以工作（如果我在代码下面注释），这意味着可以正确添加到项目中。WakefulBroadcastReceiver cannot be resolved to a typeandroid-support-librarygoogle play servicesgoogle play service

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);
    }
}

任何想法为什么这给错误？
