In my android application an activity takes more than 10 seconds to load (it contains a number of TextViews with lengthy text values), now I want to show a progress bar dialog window during the Activity loading? Is it possible by using 'AsyncTask'? if possible then how can I pause the UI thread until AsyncTask to complete,.When I tries to show a dialog before setContentView() call I got an error like android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application

trying to show a dialog before setContentView() will give you this sort of error only.Show after it and dismiss after setting textview – AkashG Jul 19 '12 at 12:03

You can use AsyncTask and Viewswitcher to switch between two layouts(each layout is a view).First set your contentView and in onPostExecute(after loading) switch your layouts.
Edit:
