title: How to retrieve the download link for a not supported doc hosted on Google Docs?
body: <p>Google's official doc tells us :</p>
  
  <pre><code> The download URL for files looks something like this:
   https://doc-04-20-docs.googleusercontent.com/docs/secure/m7an0emtau/WJm12345/YzI2Y2ExYWVm?h=16655626&amp;e=download&amp;gd=true
  </code></pre>
  
  <p>And it also tells us that a document entry xml is done like following :</p>
  
  <pre><code>&lt;entry ...
  ...
  &lt;content type='application/zip' src='https://doc-0s-84-docs.googleusercontent.com/docs/securesc/4t...626&amp;amp;e=download&amp;amp;gd=true'/&gt;
  ...
  &lt;/entry&gt;
  </code></pre>
  
  <p>But whatever I try with gdata java client library, I don't manage to retrieve that url. I tried all the .get*<em>Link</em>*() methods, and .getContent(). Does somebody met this issue and found the solution ? I've also tried to get the mediasource and work on its input stream.</p>
  
  <p>The finality of that is to get the file's content (the file is binary with a custom format) back on my java application server (GAE) to send it to my client who can parse it and view it.</p>
  
  <p>Cheers,</p>
