Как получить объект службы внутри действий?

Вот код моей службы:

public class DownloadService extends Service {
    LocalBroadcastManager mLocalBroadcastManager;
    ArrayList<DownloadAsyncTask> dat = new ArrayList<DownloadAsyncTask>();
    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }

    @Override
    public void onStart( Intent intent, int startId ) {
          super.onStart( intent, startId );
          Log.d("service","DownloadService started");
    }
    public void startDownload(String url, String fname, ProgressBar pBar){
        int dID = dat.size();
        Log.d("status","dat length:"+dID);
        dat.add( new DownloadAsyncTask(url,fname,pBar));
        dat.get(dID).execute();
    }

    public void cancelDownload(String fname){
        for(DownloadAsyncTask da: dat){
            if(da.getName().equals(fname)){
                da.cancel(true);
            }
        }
    }

    public DownloadAsyncTask getDownloadByName(String fname){
        for(DownloadAsyncTask da: dat){
            if(da.getName().equals(fname)){
                return da;
            }
        }
        return null;
    }

Я использую эту службу для управления несколькими загрузками. Теперь мне нужно получить доступ к этому сервисному объекту внутри различных действий, чтобы иметь возможность добавлять загрузки или получать список текущих загрузок. Как мне это сделать?
