Boy, you are kind of making this hard to sort out ;) What is the name of the AsyncTask subclass?
It looks to me as if the variable "pd" is assigned different dialogs at different times? What is the value of the variable "activity" when onPreExecute is called? ...and, it seem that you've posted two different implementations of onPreExecute? It looks to me as if one of those dialogs is being created when the context is null, or at least invalid. I totally cannot figure out, from the fragments you've posted, though, why that is. G.
