title: Android youtube/gdata api not working after running proguard
body: <p>Did anyone have trouble with youtube api especially after running proguard?
  My code to fetch videos from youtube worked just fine before running proguard, after running proguard i am getting strange exception </p>
  
  <pre><code> ERROR/AndroidRuntime(10197): Caused by: java.lang.IllegalArgumentException: 
  No parser defined for Content-Type: application/atom+xml; charset=UTF-8; type=feed
  </code></pre>
  
  <p>I'm not setting content type anywhere and i'm using the default proguard.cfg file that's generated while creating a new project.<br>
  Did anyone face similar issues after running proguard?
  Tried proguard without obfuscating, without optimization but it gives the same result.</p>
