title: Sending one event from one activity to multiple fragment
body: <p>I'd like my activity to send the same event to multiple fragment. Instead of making my activity calling each individual fragment method  : <code>FragmentA.DoTask()</code>, <code>FragmentB.DoTask()</code>, <code>FragmentC.DoTask()</code>, etc... I'd like rather make my activity send only one event and then make the fragment listening to this event.</p>
  
  <p>On the developpers docs they make the activity "listen" to the fragment but then the activity calls the fragments' methods. Is it possible the other way around : to make the fragments "listen" to the activity.</p>
  
  <p>Thanks</p>
