I you are adding progress bar in background thread then this

android.view.WindowManager$BadTokenException

exception occurs. If you are using asynkTask class for some background work than you can't use progressDialog or AleartDialog in postexecute method.

If you want to do something like this you can use AsynkLoader class which overrides loadInbackground method in which you can perform background work and then implement LoaderManager.LoaderCallBacks in your main activity which will override onLoadfinish() that will be in main thread so for that you can use dialogbox or ProgressBar
