Answer 1

class MyLocationActivity
     extends MapActivity {
    MapController mapController;
    MyPositionOverlay positionOverlay;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        MapView mapView = (MapView) findViewById(R.id.mapview);
        mapController = mapView.getController();
        // Configure the map display options
        mapView.setSatellite(true);
        mapView.setStreetView(true);
        mapView.displayZoomControls(false);
        mapController.setZoom(17);
        // Add the MyPositionOverlay
        positionOverlay = new MyPositionOverlay();
        List<Overlay> overlays = mapView.getOverlays();
        overlays.add(positionOverlay);
        LocationManager locationmanager;
        String context=Context.LOCATION_SERVICE;
        locationmanager=(LocationManager) getSystemService(context);
        String provider=LocationManager.NETWORK_PROVIDER;
        Location location= locationmanager.getLastKnownLocation(provider);
        updateWithNewLocation(location);
    }
    private void updateWithNewLocation(Location location) {
        if(location!=null){
            positionOverlay.setLocation(location);
            Double lat=location.getLatitude()*1E6;
            Double lon=location.getLongitude()*1E6;
            GeoPoint point = new GeoPoint(lat.intValue(),lon.intValue());
            mapController.animateTo(point);
        }
        else{


        }

    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }
}

Use the LocationManager to register for location updates. You indicate which level of granularity you want by specifying a provider. For cell tower updates, use the NETWORK_PROVIDER.
