title: android get and parse Google Directions
body: <p><a href="http://code.google.com/apis/maps/documentation/directions/" rel="noreferrer">google Directions API</a></p>
  
  <p>I read this guide now I can build a correct request to receive the xml file containg the directions from address A to address B. What I need is some instructions and example on how to read this xml to draw the obtained directions on an Android MapView. I'd like also to know what represents this tag in the xml: </p>
