Android: how to draw bitmap behind some path?
<p>The task is following: </p>

<p>To draw parts of some bitmap only behind a path (user draws path using his finger). It must look like the user draws this bitmap by his finger. It is similar to task: erasing some picture by finger, but the approach should be different.</p>

<p>I know it is possible with OpenGL, but at first i am looking for more light option with standard android canvas and view drawing.</p>

<p>I have seen the example FingerPaint in APIDemos (please, do not refer me to it).</p>

<p>I am interested in somebody's real experience of implementing this task, or any other info, links or code, which can help.
Thanks.</p>
