How to read the current location in a blackberry application

How do I read the latitude and longitude of current location in a开发者_开发知识库 black berry application?

Look at using these classes: LocationProvider, Location, QualifiedCoordinates.

LocationProvider provider = LocationProvider.getInstance(null);
Location loc = provider.getLocation(-1);
QualifiedCoordinates qc = loc.getQualifiedCoordinates();
//Call getLatitude() and getLongitude() in QualifiedCoordinates object.
