You can use Android SDK function distanceBetween.

Computes the approximate distance in meters between two locations, and optionally the initial and final bearings of the shortest path between them. Distance and bearing are defined using the WGS84 ellipsoid.

Try this, You will get distance

 private String distance(double lati, double longi, double curlati1,
        double curlongi1) {

    double theta = longi - curlongi1;
    double dist = Math.sin(deg2rad(lati)) * Math.sin(deg2rad(curlati1))
            + Math.cos(deg2rad(lati)) * Math.cos(deg2rad(curlati1))
            * Math.cos(deg2rad(theta));
    dist = Math.acos(dist);
    dist = rad2deg(dist);
    dist = dist * 60 * 1.1515;

    dist = dist * 1.609344;

    result = Double.toString(dist);
    System.out.println("dist_result :" + result);
    return (result);
}

/* ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: */
/* :: This function converts decimal degrees to radians : */
/* ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: */
private double deg2rad(double deg) {
    return (deg * Math.PI / 180.0);
}

/* ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: */
/* :: This function converts radians to decimal degrees : */
/* ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: */
private double rad2deg(double rad) {
    return (rad * 180.0 / Math.PI);
}
