how to find the distance between two geopoints?

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);

the above code is not working and i am getting 0.0 Km as distance? Also in the constructor of the location class, what does the string provider mean. In the above code i am using PointA and PointB as the providers.

why is the above code not working?

thank you in advance.

Solution

  • Try Location.distanceBetween(..)

    Update:

    If you are getting lat/lon from GeoPoint then they are in microdegrees. You must multiply by 1e6.
