title: Blank screen when packaging with Phonegap
body: <p>When I package my Sencha Touch app with Phonegap builder (https://build.phonegap.com/) I don't get any errors with building.
  Although, when I start the app I get a blank (white) screen and nothing happens.</p>
  
  <p>What could I do wrong?</p>
  
  <p>My index.html file looks like this:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;My app&lt;/title&gt;
  &lt;link rel="stylesheet" href="app.css" type="text/css"&gt;
  &lt;link href="resources/css/app.css" rel="stylesheet" type="text/css" /&gt;
  &lt;link href="resources/plugins/SliderFieldExtended.css" rel="stylesheet" type="text/css"    /&gt;
  &lt;link href="styles/OrangeTheme.css" rel="stylesheet" type="text/css" /&gt;
  &lt;script src="resources/lib/sencha-touch-all.js" type="text/javascript"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="app.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="resources/plugins/SliderFieldExtended.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"&gt;     &lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;&lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>PS. I'm using Sencha Touch 2.0.1.</p>
  
  <p>Thanks in advance.</p>
