title: Travel Distance between two Lat and Long
body: <p>I am looking to calculate and give the distance between two sets of Lat and Long for travel on Road. </p>
  
  <p>I have had a look at the Google's Directions and Distance Matrix API. And also done a lot of other questions on SO.</p>
  
  <p>But i am not able to figure out the best possible way to do it, you need to calculate the distance to around 20-25 locations at each time.</p>
  
  <p>We are building a travel app that requires this information for the user on Android device from where he is.</p>
