title: How do i refresh a ListFragment list based on other fragment's method?
body: <p>I have the tipical 2-fragment display on a RSS reader app.
  One fragment with the list of titles, and one fragment with the detail of the selected title.</p>
  
  <p>It works perfect on mobile devices, but on tablets (and wide devices) i can not refresh the list (the cursor i mean), to mark the items as read.</p>
  
  <p>Any idea about how to get it done, how to get the fragment "refreshed" or something like that?</p>
