Re: [android-developers] Problem while updating adapter from AsyncTask

Hi Piren,

I am creating AsyncTask in onCreate() method of Activity.  I am modifying adapter in doInBackground() method of AsyncTask. And finally calling adpater.notifyDataSetChanged() method.

Are you creating that AsyncTask in a background thread as well?

Yes I am updating adapter in onPostExecute() method (as it runs in UI thread). In onPostExecute() method i am simply calling adpater.notifyDataSetChanged().

Make sure that you are updating your adapter in onPostExecute(), and
make sure that either the adapter calls notifyDataSetChanged() or you
call notifyDataSetChanged() on the adapter.
