Get the distance between two locations in android?

Question

i need to get distance between two location, but i need to get distance like blue line in the picture.

Answer 1

Try this:

private double calculateDistance(double fromLong, double fromLat,
            double toLong, double toLat) {
        double d2r = Math.PI / 180;
        double dLong = (toLong - fromLong) * d2r;
        double dLat = (toLat - fromLat) * d2r;
        double a = Math.pow(Math.sin(dLat / 2.0), 2) + Math.cos(fromLat * d2r)
                * Math.cos(toLat * d2r) * Math.pow(Math.sin(dLong / 2.0), 2);
        double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
        double d = 6367000 * c;
        return Math.round(d);
    }

Hope this helps.
