Current position on google maps [closed]

Answer 1

Don't know i havent gone through the code but following code works for me:

public class GoogleMapsActivity extends MapActivity {
    public static final String TAG = "GoogleMapsActivity";
    private MapView mapView;
    private LocationManager locationManager;
    Geocoder geocoder;
    Location location;
    LocationListener locationListener;
    CountDownTimer locationtimer;
    MapController mapController;
    MapOverlay mapOverlay = new MapOverlay();

    @Override
    protected void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.googlemap);
        initComponents();
        mapView.setBuiltInZoomControls(true);
        mapView.setSatellite(true);
        mapController = mapView.getController();
        mapController.setZoom(16);
        locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
        if (locationManager == null) {
            Toast.makeText(GoogleMapsActivity.this,
                    "Location Manager Not Available", Toast.LENGTH_SHORT)
                    .show();
            return;
        }
        location = locationManager
                .getLastKnownLocation(LocationManager.GPS_PROVIDER);
        if (location == null)
            location = locationManager
                    .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
        if (location != null) {
            double lat = location.getLatitude();
            double lng = location.getLongitude();
            Toast.makeText(GoogleMapsActivity.this,
                    "Location Are" + lat + ":" + lng, Toast.LENGTH_SHORT)
                    .show();
            GeoPoint point = new GeoPoint((int) (lat * 1E6), (int) (lng * 1E6));
            mapController.animateTo(point, new Message());
            mapOverlay.setPointToDraw(point);
            List listOfOverlays = mapView.getOverlays();
            listOfOverlays.clear();
            listOfOverlays.add(mapOverlay);
        }
        locationListener = new LocationListener() {
            @Override
            public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
            }

            @Override
            public void onProviderEnabled(String arg0) {
            }

            @Override

            }

            @Override

                location = l;
                locationManager.removeUpdates(this);
                if (l.getLatitude() == 0 || l.getLongitude() == 0) {

                }
            }
        };
        if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER))
            locationManager.requestLocationUpdates(
                    LocationManager.GPS_PROVIDER, 1000, 10f, locationListener);

    }

    public MapView getMapView() {
        return this.mapView;
    }

    private void initComponents() {
