title: User navigation on google maps - how to?
body: <p>I'm an averagely experienced Android programmer.
  I'm currently working on an app that includes the google maps API and among the activities there are two views that include a map fragment. Now I want someone to be able to navigate on one of those views, called mapActivtiy. It basicly consists of a map, that's all. After choosing a location in another view, I want the map to display the direction from the users position (which I already know) and the target's location.</p>
  
  <p>Now, in iOS I'd just throw in the <code>MKDirections</code> stuff from the MapKit framework, but I seem to be unable to find something equivalent for android. Is there any API or something for wayfinding and navigation on the map? If so, where to look for it? </p>
  
  <p>Just to clearify this: I know I can call the google navigation app from my app, but I don't (really) want to do that, I'd prefer staying within my context. Using the navigation app is more of a last resort.</p>
  
  <p>Does anyone have a smart adivce for me?
  Any idea would be much appreciated!</p>
