I think you are going to have to go with Studio LFP. Checking an update say ever 5 or 10 minutes with GPS won't kill the battery that fast. Atleast with my application it doesn't just don't leave the GPS listener open. I set an alarm to go off every X minutes, first I try a course location (off 3g or wifi) if I can't get a location I try a fine location (off GPS) I have had the app run for 24 hours in the background checking every 5 minutes and didn't notice much of a difference from when it wasn't running.

If so, problem solved! If not, as Studio LFP said, my only idea in mind was updating (every 5 min, for example) with the latest location coordinates, upload to db, check for coords in range and then get the information from the users in range. However, that would obviously require having GPS turned on (or maybe not, if wifi or 3g can provide location coordinates) with the inherent battery draining :(. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
