title: after onDestroy, the life cycle callbacks are re-called
body: <p>I have a main activity with viewpager and three tabs, each tab has its own fragment layout. in each of the three fragment i implemented the life cycle
  call backs. The app was working fine till I pressed the the button that turns the screen off. when the screen turned off i found that after the
  the three fragments destroyed they got recreated again and <code>onAttach</code>, <code>onCreate</code>,....etc were called again as well as shown in the logs posted below.</p>
  
  <p>please let me know why when i turn the screen off <code>onAttach</code>, <code>onCreate</code>,.....etc are re-called?</p>
  
  <p><strong>logcat</strong>:</p>
