No - only onCreateDialog does. onPrepareDialog also passes you the Dialog
it's preparing ... otherwise it would be rather useless.

Store the number of files somewhere in the activity, and in onPrepareDialog,
which, again, gives you the Dialog, call dialog.setMessage("Number of file:
" + numberOfFiles);

Where does it say these functions are called asynchronously? Anything
dealing with any UI elements (like a Dialog) is pretty much guaranteed to be
running on the UI thread.
