title: Android icon generator for actionbar and notification not working (grey shape)
body: <p>I found this <a href="http://romannurik.github.io/AndroidAssetStudio/" rel="noreferrer">Asset Studio</a> to generate icons. It works fine for the launcher icon but for action bar or notification icons it is not working. I put in my png file and want to generate the icons, but Asset Studio is only generating gray circles. Is there another tool to generate action bar and notification icons?</p>
