title: How avoid Restarting of Fragment
body: <p>I am working on Fragments. I am using Navigation Drawer(Sliding Menu) with Action Bar activity.</p>
  
  <p>Navigation Drawer having 4 menu items.Each Menu Item has Separate Fragment like:</p>
  
  <p>Fragment 1,Fragment 2,Fragment 3, Fragment 4.</p>
  
  <p>By default Fragment 1 will be opened. Based on the selection from the menu particular fragment screen will be opened.</p>
  
  <p>If we are opening a same fragment again the fragment is restarting.So here my problem is <strong>fragment should not be restarted as it opened again</strong>.</p>
  
  <p>I don't have much idea about fragments whether it is possible to <strong>avoid restarting the fragment</strong> when we are not opening it first time.
        So can any body help whether it is possible or not?   </p>
