try like this your Activity must be like this

Activity extends MapActivity implements LocationListener

 LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
 Criteria criteria = new Criteria();
 String provider = locationManager.getBestProvider(criteria, false);
 Location location = locationManager.getLastKnownLocation(provider);

    if (location != null) {
        System.out.println("Provider " + provider + " has been selected.");
        lat = (double) (location.getLatitude());
        lng = (double) (location.getLongitude());

        Log.i(TAG, "Lattitude:" + lat);
        Log.i(TAG, "Longitude:" + lng);

    }

Just becuase your device has not the last known location, thats why. First make the code for onLocationChanged(). It will get the current location and save it as lastKnownLocation. Then the method will work.

You can take help for current location here

How do I get the current GPS location programmatically in Android?
