Um, some shots in the dark:

-Are you sure the view is not null and has a width and height that you can retrieve at the time of the call? I would have a check for that at the beginning- throw an error or return a null if the View v is null.

-The method getWidth() returns a final int. I’m not a java expert but maybe that is messing something up, so try setting iwidth and iheight to getWidth() and getHeight() and then see if it works.
