Re: [android-developers] Problem while updating adapter from AsyncTask
Earlier you said you update the adapter in onPostExecute (as you should), now you're saying you're doing it in doInBackground (which is wrong and will cause this error), so which is it?

Re: [android-developers] Problem while updating adapter from AsyncTask
Thanks Piren! Actually in doInBackground method - I am fetching icons of all installed apps and replacing the default icon( which I had set while creating list to show all installed apps) with new one. Once I am done with this I am simply notifying to adapter for data set change inside the postExecute() method. I am using approach suggested by someone in below site - http://impressive-artworx.de/2011/list-all-installed-apps-in-style/ -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Problem while updating adapter from AsyncTask
try moving mAdapter.setIcons(icons); to onPostExecute (you'll have to make icons a member of your asynctask) On Monday, November 5, 2012 10:40:14 AM UTC+2, Bajrang Asthana wrote: Thanks Piren!

Re: [android-developers] Problem while updating adapter from AsyncTask
Yes I did that and work fine. I added all the changes in temporary object and then updated the content of adapter and notified it in postExecute() method.
