title: Android tracking x,y coordinates draw from Path
body: <p>I am trying to develop an android application (targeting versions 2.1/2.2) which requires the tracking of Path x,y coordinate points and am having a hard time.  The basics of the app are similar to FingerPaint, except first a separate thread draws some lines using a Path drawable onto a canvas, then the user tries to draw over those lines, covering them completely with a different Paint and Path object.  The user will have a larger Paint brush than the computer.  The first auto drawn lines use a separate thread similar to LunarLander example app.  Since the lines are not just straight lines I'm struggling finding an approach to do the following:
  1.  Track the auto points draw.  I realize I'm providing the basic points but using <code>path.lineTo</code> and <code>path.arcTo</code> and <code>path.quadTo</code> to really figure out all the points.  </p>
  
  <ol>
  <li>Once I know all the points the auto path drew, monitor and detect when user has drawn over all those points and "wins" that round.</li>
  </ol>
  
  <p>My ideal method which obviously doesn't exist would be something like
  <code>autoPath.getDrawnPoints().coveredBy(userPath.getDrawnPoints()) == true</code> ?
  Any help with this would be greatly appreciated, thank you.
