22,341 PointsHow can I use getLatitude() and getLongitude() in LocationHandler ?
Where should theses methods come from ?
public class GeolocationService extends Service {
int mLatitude;
int mLongitude;
// some methods omitted
@Override
public IBinder onBind(Intent intent) {
return null;
} // onBind()
class LocationHandler extends Handler {
private GeolocationService geolocationService;
public LocationHandler (GeolocationService geolocationService) {
this.geolocationService = geolocationService;
} // LocationHandler
public void handleMessage(Message msg) {
// Where should theses methods come from ?
mLatitude = getLatitude();
mLongitude = getLongitude();
} // handleMessage()
} // LocationHandler()
} // GeolocationService

I tried the code you gave, and to get it to work you need to remove the constructor and GeoLocationService field of the inner class. Because it's a non-static inner class it will automatically have a reference to it's outer class object, and they aren't necessary.
