title: Launch Android Map intent with specific direction overlay from directions API result
body: <p>I'm making a navigation application, I have a bunch of routes being returned from Googles Directions API (set alternatives to true), which the user will then choose from. What I'd like to do is launch the Map intent for Google Maps with the selected route passed in.</p>
  
  <p>I'm wondering if this is possible?</p>
  
  <p>I've seen examples of passing in saddr and daddr which will automatically show the best route, but instead I'd like it to display the one selected by a user from one of the direction results which may not the best (most optimum).</p>
  
  <p>Thanks</p>
