title: How do I increase Facebook API's session length?
body: <p>I'm using Facebook's Graph API from Android.</p>
  
  <p>First, what is the default session length (time)?  The ONLY resource I've found stating anything helpful and relevant is from <a href="https://developers.facebook.com/blog/post/500/" rel="nofollow" title="How-To: Handle expired access tokens">this Facebook blog post</a> which suggests the default is 2 hours.</p>
  
  <p>Is there a way to set the session timeout?  If that's the default, one would reason that it can be set.  It'd be great if I could set it for, say, 24 hours.  If it can't be set, do you have a strategy for how you deal with it, without making the user login all the time?  For example, if the session time automatically increases on the server side (say, by 2 hours) with each call to the API, then I'd implement a strategy where I'd call SOME API method every, say, 2-ish hours.</p>
  
  <p>Note that I am aware of the <code>offline_access</code> permission.  That seems like overkill.</p>
