how to find the distance between two geopoints?

Question

double distance;  

Location locationA = new Location(\"point A\");  

locationA.setLatitude(latA);  
locationA.setLongitude(lngA);  

Location locationB = new Locat         


        

Answer 1

Just a quick snippet since I didn't see a complete and simple solution with GeoPoints above:

public float getDistanceInMiles(GeoPoint p1, GeoPoint p2) {
    double lat1 = ((double)p1.getLatitudeE6()) / 1e6;
    double lng1 = ((double)p1.getLongitudeE6()) / 1e6;
    double lat2 = ((double)p2.getLatitudeE6()) / 1e6;
    double lng2 = ((double)p2.getLongitudeE6()) / 1e6;
    float [] dist = new float[1];
    Location.distanceBetween(lat1, lng1, lat2, lng2, dist);
    return dist[0] * 0.000621371192f;
}

If you want meters, just return dist[0] directly.
