You have three protected methods in an AsyncTask that can interact with the UI.

• onPreExecute()
  • runs before doInBackground()
• onPostExecute()
  • runs after doInBackground() completes
• onProgressUpdate()
  • this only runs when doInBackground() calls it with publishProgress()

If in your case the Task runs for a lot longer than the 30 seconds you want to refresh you would want to make use of onProgressUpdate() and publishProgress(). Otherwise onPostExecute() should do the trick.

See the official documentation for how to implement it.
