I am using Google Maps for finding the location on a provided address.

I want to store the image of location which I get from Google Maps onClick.

Does anyone know how to do this?

Here is my code for google map & storing onClick

public class TestGPSActivity extends MapActivity 
 {    
MapView mapView;
private MapController mc;
private GeoPoint p;
private double lng;
private double lat;
private Address address;
private View mCurrentUrlMask;
private File imageFile; 

class MapOverlay extends com.google.android.maps.Overlay
{
    @Override
    public boolean draw(Canvas canvas, MapView mapView, 
            boolean shadow, long when) 
    {
        super.draw(canvas, mapView, shadow);                   

        //---translate the GeoPoint to screen pixels---
        Point screenPts = new Point();
        mapView.getProjection().toPixels(p, screenPts);

        //---add the marker---
        Bitmap bmp = BitmapFactory.decodeResource(
                getResources(), R.drawable.pin);            
        canvas.drawBitmap(bmp, screenPts.x, screenPts.y-50, null);         
        return true;
    }
} 
public boolean onTouchEvent(MotionEvent event, MapView mapView) 
{   
    //---when user lifts his finger---
    if (event.getAction() == 1) {                
        GeoPoint p = mapView.getProjection().fromPixels(
                (int) event.getX(),
                (int) event.getY());

        Geocoder geoCoder = new Geocoder(

        try {
            List<Address> addresses = geoCoder.getFromLocation(
                    p.getLatitudeE6()  / 1E6,

Please help me out.. thanks in advance

I have solved this problem. I was having problem with image capturing of GPS location. I have just created the capture menu, In which after uploading the GPS location one can capture the image by clicking on capture menu button.

Here is the whole code for capturing the screenshot of GPS location & how to find GPS location.

public class TestGPSActivity extends MapActivity 
{    
MapView mapView;
private MapController mc;
private GeoPoint p;
private double lng;
private double lat;
private Address address; 

//google Map
class MapOverlay extends com.google.android.maps.Overlay
{
    @Override
    public boolean draw(Canvas canvas, MapView mapView, 
            boolean shadow, long when) 
    {
        super.draw(canvas, mapView, shadow);                   

        //---translate the GeoPoint to screen pixels---
        Point screenPts = new Point();
        mapView.getProjection().toPixels(p, screenPts);

        //---add the marker---
        Bitmap bmp = BitmapFactory.decodeResource(
                getResources(), R.drawable.pin);            
        canvas.drawBitmap(bmp, screenPts.x, screenPts.y-50, null);         
        return true;
    }
} 
public boolean onTouchEvent(MotionEvent event, MapView mapView) 
{   
    //---when user lifts his finger---
    if (event.getAction() == 1) {                
        GeoPoint p = mapView.getProjection().fromPixels(
                (int) event.getX(),
