Question

I am having an issue calculating distance using the Location.distanceTo method.

private class MyLocationOverlay1 extends MyLocationOverlay {     @Override     public void drawMyLocation(Canvas canvas, MapView mapView, Location lastFix, GeoPoint myLocation, long when)          super.drawMyLocation(canvas,mapView,lastFix,myLocation,when);          Location bLocation = new Location('reverseGeocoded');         bLocation.setLatitude(FindList.gpslat);           // Value = 3.294391E7         bLocation.setLongitude(FindList.gpslong);         // Value = -9.6564615E7         Location aLocation = new Location('reverseGeocoded');         aLocation.setLatitude(myLocation.getLatitudeE6());   // Value = 3.2946164E7         aLocation.setLongitude(myLocation.getLongitudeE6()); // Value = -9.6505141E7         aLocation.set(aLocation);    // Don't think I need this            bLocation.set(bLocation);    // Don't think I need this either          int distance = (int)aLocation.distanceTo(bLocation);  // Value = 12637795 ???         String str = ' (' + String.valueOf(distance) + ' meters)';     } } 

Can someone tell my why my distance calculation is showing 12,637,795 Meters?

You should Modify lines:

aLocation.setLatitude(myLocation.getLatitudeE6() / 1e6); aLocation.setLongitude(myLocation.getLongitudeE6() / 1e6); 

And remove the lines:

aLocation.set(aLocation); bLocation.set(bLocation);
