Android has a distanceTo method that does this for you, it's in the
Location class (see
http://developer.android.com/reference/android/location/Location.html#distanceTo%28android.location.Location%29)
So, for instance:
Location amsCentral = new Location("Amsterdam CS");
amsCentral.setLatitude(52.3791);
amsCentral.setLongitude(4.9002);
Location histMuseum = new Location("Historical Museum");
histMuseum.setLatitude(52.370247);
histMuseum.setLongitude(4.889731);
float distanceInMeters = histMuseum.distanceTo(amsCentral);
(P.S. The distance between the above two locations is 1216.0496
meters ;-)
