Saving a Drawing
<p>I am building an app that uses Android's Canvas and Drawables.</p>

<p>What is the best way to save a drawing for later modification?  Say it has lines and icons that I want a user to be able to save and still be able to modify each component of the drawing at a later date.</p>

<p>I know I can save the drawing as a .png or .jpg, but then it can't be edited later.  I found a way to render SVG files to Canvas, but not the other way around.</p>
