title: Can't disable Sandbox mode in Facebook application settings
body: <p>I created a Facebook app in <a href="http://www.facebook.com/developers/" rel="nofollow">http://www.facebook.com/developers/</a> to get an Application ID, following the instructions given <a href="http://developers.facebook.com/docs/guides/mobile/#android" rel="nofollow">here</a>.

  <pre><code>Validation failed.
  Tried to switch out of sandboxed mode while still using an FBML Canvas. Need to switch to an IFrame Canvas before disabling sandbox mode.
  </code></pre>
  
  <p>What's wrong? I only set the name of the app and the android hashkey. Do I have to set something else (like Facebook Integration settings)?</p>
  
  <p>Thanks</p>
