Android,后台服务无法启动

我正在实现一个执行后台服务的简单应用程序,我无法启动该服务,以下是我的Manifest&代码,服务类已正确解析(读取资源),继承自IntentService(并实现req方法)并不能解决问题...

为什么后台服务无法启动?
任何帮助将不胜感激。

服务代码:

package com.newcomp.vagent;

import android.app.IntentService;
import android.app.Service;
import android.content.Intent;
import android.R.*;
import android.os.IBinder;

import java.io.IOException;

import fi.iki.elonen.NanoHTTPD;

    public class CaptureService extends Service {
    public CaptureService() {
        //super("Capture Service");
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        return Service.START_NOT_STICKY;
    }

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
    }
}

活动代码:     包com.newcomp.vagent;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;

public class MainActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        final String strSvcName = getResources().getString(R.string.startup_service);
        //setContentView(R.layout.main);
        Toast.makeText(getBaseContext(), String.format("Hello from '%s'", strSvcName), Toast.LENGTH_LONG).show();
        Class cls = null;
        try {
            cls = getClassLoader().loadClass(strSvcName);
            startService(new Intent(this, cls));// Starts the service
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }

        //finish();
    }
}

问题很简单,服务实际上已经启动但是由于 android:process =“:captureService”被指定它是在一个单独的进程上启动的,一个未被调试器连接的进程,特定地连接到服务进程,或者,省略 android:process =“:captureService”解决问题。
