Android - Reliably getting the current location

Question

My app checks at a specific time whether a user is at a given location. I use the alarm manager to start a service that makes this call:

locationManager.requ         


        

Answer 1

If the user's location is already stable, then getLastKnownLocation will return the current location. I'd call getLastKnownLocation first, look at the timestamp (compare Location.getElapsedRealTimeNanos() with SystemClock.elapsedRealTimeNanos()) then register a listener if the fix is too old.
