Answer 1

This happened to me when i am using ProgressDialog in AsyncTask. Actually i am using hide() method in onPostExecute. Based on the answer of @Alex Volovoy i need to use dismiss() with ProgressDialog to remove it in onPostExecute and its done.

progressDialog.hide(); // Don't use it, it gives error

progressDialog.dismiss(); // Use it
