On my application (picture 1), i use computeDistanceBetween() to count the distance between location A and location B, and i use addPolyline to draw the line between 2 locations.

Can i get distance between location A and location B like Google Maps Application (picture 2)?  
because when using computeDistanceBetween() the return value not same like distance on Google Maps Applications?

And can i draw line between 2 locations like on Google Maps Application (fastest route)? not only draw a straight line between 2 locations like picture 1.

`computeDistanceBetween()` calculates the distance (in meters) two linear points.

In order to get the routes of two points, you need to implement [Google Maps Directions API](https://developers.google.com/maps/documentation/directions/start) by yourself.
