Achievement update service:

package whiskeymedia.com;

import java.io.IOException;

import java.util.List;

import whiskeymedia.com.vo.Achievement;
import android.app.Service;
import android.content.Intent;

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<Achievement> 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;
    }
  }

}

Any idea what I am doing wrong?

The crash is because the binder you're getting back is an instance of BinderProxy, not your local binder class. This usually happens because your activity is attempting to bind to a service that is not in the same process. When binding across process boundaries, an instance of BinderProxy is used instead of the actual instance (since that's in a different process).

What does your AndroidManifest.xml look like?
