Answers on This SO question and to a lesser extent the answers on This SO question seem to indicate you are suffering from an unfortunate Caching issue in the FusedLocationApi caused by onLocationChanged being called with an out of date timestamp (thus ignoring the result as it thinks there is already newer data).

To quote Reno's answer:

Unless you have not changed ... so that new APs can be discovered, I'm afraid you will get only cached locations. If you want fresh locations use the GPS provider.

The solution will be to instead call a location from the GPS Provider like so:

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
LocationListener locationListener = new MyLocationListener();
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5000, 10, locationListener);

(The code above comes from a longer example here)
