title: Activity with ProgressBar -> Service -> AsyncTask for downloading - but how to update the progress?
body: <p>this is the current state/situation: I have an Activity which binds a Service which creates AsyncTasks which downloads various web resources. That works well, but of course the ProgressBar shows nothing.</p>
  
  <p>Previously i had an Activity which created an AsyncTask which downloaded some stuff. The AsyncTask got the View which holds the ProgressBar. So i could update the progress using onProgressUpdate and publishProgress. Obviously this doesn't work any longer because I have no reference to the ProgressBar.</p>
  
  <p>So, do you have any idea on how to update the progress?</p>
  
  <p>Thanks in advance.</p>
