title: Call an activity method from a fragment
body: <p>Trying to call a method in my activity from a fragment. I want the fragment to give the method data and to get the data when the method return. I want to achieve similar to call on a static method, but without the use of static because it create problems in the activity. </p>
  
  <p>New to fragments so I need an easy and pedagogic explanation!</p>
  
  <p>Thanks!</p>
