19. getPosition() the right strategy in getting GPS
By: Fazal : 2007-09-22
Description: This article describes using the getPosition() method to get the GPS position in the background. I call this method from a separate thread like documentation recomends, so I can show a 'Cancel' button in the display in case I want to cancel the GPS request. The thing is that I don't know how to make getPosition() function to stop requesting. I want getPosition() to stop executing when I push 'Cancel' button. How do I do that? I'm sure there is a way, because the built-in app to get GPS position stops when I cancel.
