Wifi broadcast would be ideal, since it is less power-consuming than GPS, but is it possible to send a wifi broadcast from my application and other users with the same application can detect that broadcast and get the information from the emisor? 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.
