title: Adding waypoints on mobile app which uses Google Maps API 3.0
body: <p>I am working on the app for Android and iOS platforms. My client requires that the app has to have "add directions" functionality.
  Let's say I have a TO and FROM points set on my app, and I want to show the best route between these two points. If it's just these two points it's fine. There's plenty of resources on how to proceed. But if I want to add some extra directions, like GO THROUGH for example, the internet has no answers for me.
  If you could point me to any apps (have to use Google Maps) for mobile platforms, where this functionality is working it would be great. Maybe you have some sort of documentation or some other materials on the subject.</p>
  
  <p>Thanks, Mike (poland)</p>
