我一直在尝试使此android服务正常工作，但我不知道为什么会收到此错误。

成就更新服务：

package whiskeymedia.com;

import java.io.IOException;

import java.util.ArrayList;

import java.util.List;

import whiskeymedia.com.vo.Achievement;

import android.app.Service;

import android.content.Intent;

import android.os.IBinder;

public class AchievementUpdateService extends Service{

private AchievementDatabase achievementDatabase;

private final IBinder mBinder = new MyBinder();

@Override

public int onStartCommand(Intent intent, int flags, int startId) {

HtmlParser htmlParser = new HtmlParser();

try {

List achievements= htmlParser.parseDocument();

achievementDatabase.loadAchievements(achievements);

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return Service.START_NOT_STICKY;

}

@Override

public IBinder onBind(Intent arg0) {

return mBinder;

}

public class MyBinder extends Binder {

AchievementUpdateService getService() {

return AchievementUpdateService.this;

}

}

}

知道我在做什么错吗？
