Android Calculate distance between two geo location In KM

Android: calculate distance between two geo location in KM.

Below i added code for distance between two geo location in KM

Just you have to pass Start lat , lng and Destination lat ,lag value.

Screen Shot

Source Code :

    public double CalculationByDistance(GeoPoint StartP, GeoPoint EndP) {
        double lat1 = StartP.getLatitudeE6()/1E6;
        double lat2 = EndP.getLatitudeE6()/1E6;
        double lon1 = StartP.getLongitudeE6()/1E6;
        double lon2 = EndP.getLongitudeE6()/1E6;
        double dLat = Math.toRadians(lat2-lat1);
        double dLon = Math.toRadians(lon2-lon1);
        double a = Math.sin(dLat/2) * Math.sin(dLat/2) +
        Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2)) *
        Math.sin(dLon/2) * Math.sin(dLon/2);
        double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));

//6378.1 is gravity of earth
        return  c*6378.1;
