title: Sencha touch and google Oauth 2.0
body: <p>I am developing <a href="https://www.sencha.com/products/touch/" rel="nofollow">Sencha Touch</a> application and I have been using Oauth 2.0 for authorization.  The first time it is run, the application asks for <code>user_code</code>, is authorized, and works fine.  However, when I close and then reopen the application, it again asks for authorization (the request is sent again) and asks for <code>user_code</code>.</p>
  
  <p>I read "Using OAuth 2.0 for Devices" but it did not help.</p>
