I need to write a Android app that will calculate the walking (or driving) time between 2 points, given a route.
I already can calculate the distance between 2 points using Google Maps API2 (parsing JSON output), but it gives me the time considering a default route (the is normally the shortest possible).
I can also draw a route giving several geo-points (using Polylines). But how to calculate the walking/driving time between two points, considering this polyline I've created?
