Convert String to Drawable
<p>I want to raise a notification showing an icon in the status bar - so far so good, but actually I would like this icon to be a 3 character String.</p>

<p>So my question is: Is there a way to convert my String into a <code>Drawable</code> to display it as Icon in the status bar?</p>

<p>EDIT: I recently found an app which does something similar - Battery Indicator</p>

<p>It shows the current battery level as notification icon in the status bar - I wonder if it really uses different 100 images</p>
