How to get Distance Kilometer in android?

I am very new to Google maps I want calculate the distance between two places in android.

For that I get the two places lat and lag positions for that I write the following code:

private double getDistance(double lat1, double lat2, double lon1, double lon2) {
    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));
    double temp = 6371 * c;
    temp=temp*0.621;
    return temp;
}

The above code can't give the accurate distance between two places. What is the another way to find distance please give me any suggestions.

Based on https://stackoverflow.com/a/13206484/, with one change

double distance;
Location locationA = new Location(“Point A”);
locationA.setLatitude(latA);
locationA.setLongitude(lngA);

Location locationB = new Location(“Point B”);
locationB.setLatitude(latB);
locationB.setLongitude(lngB);

// distance = locationA.distanceTo(locationB);   // in meters
distance = locationA.distanceTo(locationB)/1000;   // in km

Use code find distance meters to km and km to miles

Location locationA = new Location(“Point A”);
locationA.setLatitude(latA);
locationA.setLongitude(lngA);

Location locationB = new Location(“Point B”);
locationB.setLatitude(latB);
locationB.setLongitude(lngB);

distance = locationA.distanceTo(locationB);   // in meters
distance = locationA.distanceTo(locationB)/1000;   // in km
distance = locationA.distanceTo(locationB)/1609.344;   // in miles

Just use Location.distanceTo(Location) it will give you a really distance between two different Locations.
