title: Cordova Android Plugin: config.xml overwritten by cordova prepare?
body: <p>I'm developing a Cordova plugin for the Android platform.</p>
  
  <p>As described <a href="http://cordova.apache.org/docs/en/3.1.0/guide_platforms_android_plugin.md.html#Android%20Plugins_plugin_class_mapping">here</a>, I edited the <code>platforms/android/res/xml/config.xml</code> file to include the plugin's class mapping.</p>
  
  <p>It all works perfectly fine except that every time I run <code>cordova prepare android</code> this file get's overwritten saying:</p>
  
  <pre><code>Generating config.xml from defaults for platform "android"
  </code></pre>
  
  <p>So, I have to undo the change every time which is very annoying. Is there a way to tell cordova not to do that or insert the class mapping somewhere else?</p>
