title: how to draw route lines on imageview in android (indoor Positioning)
body: <p>I have done wifi based indoor positioning (<a href="https://github.com/mmusaab/indoor-position-tracker" rel="nofollow">my Git Project</a>), now i stuck making it more realistic,  i have to draw lines on map to redirect user to specific point.</p>
  
  <p>i have all <code>(x,y)</code> points, i want pixel distance and near far algorithms to reach at some point from specific point.</p>
