title: How to show blue arrow in Android app like Google Maps?
body: <p>How to achieve that of the Google Maps app for android (below figure) for my own app which contains a map?  </p>
  
  <p><strong>Updates</strong>  </p>
  
  <p>It appears I can achieve my goal using MyLocationOverlay + MapView according to <a href="http://joshclemm.com/blog/?p=148" rel="nofollow noreferrer">this</a>. However, it is not very clear how to make MyLotionOverlay works with MapFragment and Google Maps Android API v2 (which I'm using) after my searches yet.  </p>
  
  <p>Also, it appears that I can get the blue bubble setMyLocationEnabled(true) of GoogleMap class.<br>
  What about the arrow?</p>
  
  <p><strong>Updates</strong>  </p>
  
  <p>I did see the arrow head only once a in long while and it's not responsive at all to my change of aim, in my app actually. Now I'm more confused what's going on.
  Any ideas, anyone?</p>
