title: Android finger paint
body: <p><br>
  I m developing an application to paint the the canvas using finger stroke with the help of FingerPaint application given at the <a href="http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/FingerPaint.html" rel="nofollow">site</a> Here one of the recently drawn color overlap the color previously drawn at same palce. Is there any way to limit one or two color that doesn't get overlapped by other In other words if i had drawn red(or any that user wants) color on canvas then none of the color should hide this it will show ever n ever.Let me know if the problem is not clear to you</p>
  
  <p>thanks in advance,..</p>
