not sure why you're using the .Show() method, its best to use
onCreateDialog for custom dialogs as well.
but either way, ASyncTasks dont run onPostExecute on the UI thread
automatically, the run it on the thread the ASyncTask was created in.
To avoid your issue either add a Handler to run the onPostExecute code on
or try and using runOnUiThread
