Hi all Just updating this thread, which seems to be too old for me to post a follow-up: http://groups.google.com/group/android-developers/browse_thread/thread/df1e14fe4e9ad896/
I'm trying to check the age of a GPS fix, so that I can discard location fixes that are more than, say, a couple of minutes old - I need my fix to be very accurate. This is the code I use: long locationTime = location.getTime(); long currentTime = System.currentTimeMillis (); timeDifference = (currentTime - locationTime) / 1000; if (timeDifference > 120) { // warn the user } However, this method is entirely dependent on the user having set their system time correctly. If they are just a few minutes out (and lots of people do like to keep their clocks a few minutes fast) then they will only ever get warned. I don't know what to do - I can't accept location data that's potentially out of date, nor can I rely on my users to have correct system time within a couple of minutes. The problem is that there is no way to check the age of the GPS data itself, just the time (location.getTime() returns the UTC time, rather than the the age, of the data). Is there any way around this? I guess I could check the locationTime a few times in succession and see if it changes, and assume that if it changes then it must be getting updated, but it feels kind of fiddly.
