android ICS left caret resource
<p>The new Android design docs mention use of an Up caret: <a href="http://developer.android.com/design/patterns/actionbar.html" rel="nofollow">http://developer.android.com/design/patterns/actionbar.html</a></p>

<p>The up caret seems to be proper for navigation throughout Android - is there a proper way to add this caret? It seems unintuitive that I should just modify the icon image to include it.</p>

<p>Any help would be much appreciated!</p>
