I recommend to follow Eero's advices (email from this thread) and use those as a startinig point. Unfortunately my experience is mostly based on real measurements on real devices, but i guess that if you are running your app in quemu you should be able to detect activity from processes. However thtere are "hidden" bugs, like using buggy libraries: you expect your code to be suspended, instead it's relying on a nasty busyloop down the chain. But those should be the last problem you will face after having cleaned your app. > One question regarding your test : you asked to check wlan (or > bluetooth) wasn't active.

You are right but I tend to be very cautios when I make statements of a certain relevance; some call it paranoia, i prefer to consider it as part of being engineer :-D -- Cheers, Igor Igor Stoppa <igor.stoppa at nokia.com> (Nokia M - OSSO /Helsinki Finland)
