title: Drawble resource not found
body: <p>Getting this error:</p>
  
  <pre><code>Error:(6, 22) No resource found that matches the given name (at 'background' with value '@drawable/aegis').
  </code></pre>
  
  <p>Edit. R.Java is missing apparently. Cleaning does not regenerate it (I've cleaned it a thousand times, literally). Here's the part I'm receiving errors.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout
