calculate actual distance travelled by mobile [closed]

Answer 1

Use GPS to get lat lon of both places and after getting both pass it below method.Its will return distance in km

public static double getDistanceFromLatLonInKm(double lat1, double lon1,
        double lat2, double lon2) {



    double R = 6371; // Radius of the earth in km
    double dLat = deg2rad(lat2 - lat1); // deg2rad below
    double dLon = deg2rad(lon2 - lon1);
    double a = Math.sin(dLat / 2) * Math.sin(dLat / 2)
            + Math.cos(deg2rad(lat1)) * Math.cos(deg2rad(lat2))
            * Math.sin(dLon / 2) * Math.sin(dLon / 2);
    double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
    double d = R * c; // Distance in km


    return d;

}

public static double deg2rad(double deg) {
    return deg * (Math.PI / 180);
}

}
