I think the situation imagined is in a building with good wifi access, but crummy phone service. I hadn't thought that wifi would be that much more accurate than the cell tower location. I hadn't imagined a lookup table with 50m resolution for every wifi router in existence, I thought it was going to be more like the "location targeted" banner adds that pulled your location from your ISP. I could also see the wifi location being updated if you ever connect through it and have gps active, but prior to that I'd expect a big accuracy variance. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
