That seems pointless, but, OK. > The difficulty is that how to know the useless time. If you are looking to measure "useless time" just within your own application, you are welcome to override onTouchEvent() and onKeyDown() in each of your activities and use that to track the last time the user did something. If you are looking to measure "useless time" for the entire operating system, you will need to write your own custom firmware, AFAIK. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android App Developer Books: http://commonsware.com/books -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
