Apparently, my reply didn't go to the public list because I habitually hit 'a' when I tried to reply all in Google Groups, which does not do the job. I have been using this approach for a while. There are two problems with it. The first one is that GPS takes a while to get the first fix. The second one is power consumption. My program is set to get update every 5 minutes or 200 meters. After a day or so when I checked the battery usage, it had raised to the top of the list, consuming some 30% of all power consumed during that period. So I switched to using network location only, and my program disappeared from the list. So my opinion on this is that unless absolutely necessary, I won't use GPS as location provider frequently. It will drain the battery very fast. -- Ning -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
