title: Going back to my main activity, and refreshing the fragments
body: <p>So, my application have one activity <code>ProjectActivity</code> as a home, which contains 3 fragments <code>HomeFragment</code> <code>ListFragment</code> <code>TagFragment</code>(one for each tab). When I click on a button (on the <code>homeFragment</code>), it opens a new activity <code>CaptureActivity</code>.
  That activity launches an ASyncTask, <code>ParseData</code>.</p>
  
  <p>On the <code>ParseData</code> onPostExecute, I would like to go back to my <code>ProjectAcitity</code>, focused on a specified tab (the one that contain <code>ListFragment</code>), and update the <code>ListFragment</code> View.</p>
  
  <p>I actually have no clue on how to do that. Do I simply need to call the <code>ProjectActivity</code> ? But then, if I press the Back button, wouldn't it go back through the whole chain (<code>Project Activity</code>, <code>CaptureActivity</code>, <code>ProjectActivity</code>) ?</p>
