title: How to reuse a fragment
body: <p>When I replace a fragment, it gets destroyed. I tried to create the fragment in activity's onCreate and hold its reference in the activity and use it when I "re show" or "reopen" it by calling replace with the reference, but that did not help and the fragment got destroyed (when replaced by another fragment) and recreated. What should be the solution?</p>
  
  <p>What I'm trying to achieve is something like say WhatsApp where fragments should not be destroyed when not visible, except I'm not using a sliding gesture but rather regular buttons.</p>
  
  <p>Thanks.</p>
