runOnUiThread(new Runnable() {
                        public void run() {

                            //update UI

since there 2 threads (UI thread,handler Thread) this error is coming remove that Handler since its work in background .write the code in UI thread only(Its a main thread).

can you get me a sample code.. i mean how to run in the main thread – Sathyapradeep Apr 20 '12 at 12:31
Write the code in one method call it from onCreate(); or any Onclick Listener (if u ve)but not in ASyncTask or etc. – P Srinivas Goud Apr 20 '12 at 12:36
i do some background process for loading some data`s in a separate thread and after loading i should notify the listview.. get me a clear way to cal it from UI thread.. its not possible to recall onCreate – Sathyapradeep Apr 20 '12 at 12:43
this update should be done at a particular time ... tel me what should i do – Sathyapradeep Apr 20 '12 at 12:44
Then both Threads should be synchronized means UI Thread should not be called before data change. – P Srinivas Goud Apr 20 '12 at 12:53
yup you are rite but how should i run notifyDataSetChanged() in UI thread – Sathyapradeep Apr 20 '12 at 12:54
