是否可以在 Service 类中使用 AsyncTask？

一切都在标题中。

官方文件中指出Note that services, like other application objects, run in the main thread of their hosting process而AsyncTask只有在UIThread中执行时才有效。

那么是否可以在Service类中使用AsyncTask呢？

我正在尝试这样做，但我总是遇到同样的错误

05-01 18:09:25.487: ERROR/JavaBinder(270): java.lang.ExceptionInInitializerError

...

05-01 18:09:25.487: ERROR/JavaBinder(270): Caused by: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()

我做错了什么还是这根本不可能？

这是我的服务类的代码

package com.eip.core;

import android.app.Service;
import android.content.Intent;
import android.os.AsyncTask;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;

public class NetworkService extends Service {


    private final INetwork.Stub mBinder = new INetwork.Stub() {

        @Override
        public int doConnect(String addr, int port) throws RemoteException {
            new ConnectTask().execute("test42");
            return 0;
        }
    };

    @Override
    public IBinder onBind(Intent arg0) {
        return mBinder;
    }

    private class ConnectTask extends AsyncTask<String, Void, Void> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            Log.i("OnPreExecute()", "");
        }

        @Override
        protected Void doInBackground(String... arg0) {
            Log.i("doInBackground()", "");
            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            super.onPostExecute(result);
            Log.i("OnPostExecute()", "");
        }

    }
}

还请务必查看 IntentService。如果该类足以满足您的需求，它将处理使该模式正常工作所涉及的许多小细节。
