Location is just a class representing a geographic location.
You need to do something like this:
LocationManager lm = (LocationManager)getSystemService
(Context.LOCATION_SERVICE);
List providers = lm.getAllProviders();
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
locationListener);
Location loc = lm.getLastKnownLocation
(LocationManager.GPS_PROVIDER);
if (loc != null) {
// loc.getLatitude()
// loc.getLongitude()
}
private final LocationListener locationListener = new
LocationListener() {
public void onLocationChanged(Location newloc) {}
public void onProviderDisabled(String provider) {}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status,
Bundle extras) {}
};
Note: The getLastKnownLocation() method will return null until the
provider you specify has gotten at least one update.
