Every time the gps is started, will it fire the GPS_EVENT_FIRST_FIX if a fix was previosly taken? What I mean is that if the answer is no, then how do we know in the GpsStatus.Listener that we have a fix? And, if the list of satellites informs that none of them has been used for getting the fix, will the GPS engine try to get another fix? Sadly, the doc it's not clear enough to me. I'm trying to understand how the thing works. First, I read about GPS, the first fix definition, almanac/ephemeris, cold-start, etc that are more general. But I don't know how the android engine works. I also noticed that if you set minTime!=0 in requestLocationUpdates() the GPS engine will be turned off, then it will be started and you will get bounced values. Setting it to 0 will eat your battery, but you can measure more accurate values (and turn it off if you want with a button). -- If you want freedom, compile the source.
