Android distance are wrong

lat = 6.92961234
lng = 79.84796614

lat1 = 6.85620511
lng1 = 79.91251376 

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

locationA.setLatitude(lat);
locationA.setLongitude(lng);

Location locationB = new Location("point B");

locationB.setLatitude(lati);
locationB.setLongitude(lngi);

double distancei = locationA.distanceTo(locationB);

String cc = Double.toString(distancei);

float[] results = new float[1];
Location.distanceBetween(lati / 1E6, lngi / 1E6, lat / 1E6, lng / 1E6,results);
float s = results[0] * 0.000621371192f;
String a2 = Float.toString(s);

Two methods gives me Different answers as well as BOTH SEEMS TO BE WRONG.. since i looked at the google maps and the answers it shows about 14km(around 8mils). But the answers are showing as 6point smthing. and i dont know its on meters/km/miles.

please help me out... thank you

If you had taken the trouble to produce some code which compiled and ran, read the javadocs and had run the following corrected code through the debugger:

private void test() {

    double lat = 6.92961234;
    double lng = 79.84796614;

    double lati = 6.85620511;
    double lngi = 79.91251376;

    Location locationA = new Location("point A");
    locationA.setLatitude(lat);
    locationA.setLongitude(lng);
    Location locationB = new Location("point B");
    locationB.setLatitude(lati);
    locationB.setLongitude(lngi);

    double distancei = locationA.distanceTo(locationB);
    float[] results = new float[3];
    Location.distanceBetween(lati, lngi, lat, lng,  results);
    // Distance in metres is in results[0]
}

You would see that both distancei and results[0] give you the same answer which is 10807 metres. This seems about right to me.
