How do I create good looking drawables.
<p>For my app I need several small icons. I put them at a size of 15dp * 15dp in the layout xml file. The problem is that they do not look good on the device. If I look at the standard android Icons, e.g. for refresh, they look very sharp. </p>

<p>What I did was, I created a 15*15 pixel image with Gimp and tried to use it. I guess that is not a good approach since 15dp != 15 px, right? What is the usual workflow for creating nice, good looking icons, even if they need to be small?</p>
