What is a correct way to determine time since last location update on <4.2 Androids? This is code I've used:
long lastUpdateTime = lastLocation.getTime();
long currentTime = System.currentTimeMillis();
if (( currentTime - lastUpdateTime > 300000) || currentTime - lastUpdateTime < 0){
LocMan.requestLocationUpdates(LocationManager.GPS_PROVIDER,400,1,listener);
}
Is it OK or should I have some other approach?
API Docs state this:
Note that the UTC time on a device is not monotonic: it can jump forwards or backwards unpredictably. So always use getElapsedRealtimeNanos() when calculating time deltas.
However, pre-APIv17 (where getElapsedRealtimeNanos() was added) is still around & needs to be supported.
Thanks for the answers,

I'd leave this as a comment but I don't have that privilege yet. It seems a similar question has been asked already.
"How long ago was the last known location recorded?"
