Я решил эту проблему. У меня были проблемы с захватом изображения местоположения GPS. Я только что создал меню захвата, в котором после загрузки местоположения GPS можно сделать снимок, нажав на кнопку меню захвата.
Вот весь код для захвата скриншота местоположения GPS и как найти местоположение GPS.
public class TestGPSActivity extends MapActivity

private MapController mc;

@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(
getBaseContext(), Locale.getDefault());
try {
List<Address> addresses = geoCoder.getFromLocation(
p.getLatitudeE6() / 1E6,
p.getLongitudeE6() / 1E6, 1);
String add = "";
if (addresses.size() > 0)
{
for (int i=0; i<addresses.get(0).getMaxAddressLineIndex();i++)
