title: Back button in ActionBar gets hidden in the ListView activity started by Fragments in Tabs
body: <p>I have 3 nested activity. The first one contains 3 fragments within each is a button which starts a second activity. In the second activity I have a ListView. When the user clicks on an item in ListView the third activity is started.</p>
  
  <p>My problem is that in second activities there is no back button in action bar. </p>
  
  <p>Is the problem caused by Activity being started from within a fragment?
  I have no clue on what is causing this problem. </p>
  
  <p>My first activity is an ActionBarActivity and I use FragmentPagerAdapter.</p>
  
  <p>Please tell me which parts of the code of manifest I should put here to be considered. 
  Thanks in advance.</p>
  
  <p>(please note that I'm not willing to programmatically solve this. I need to know what is causing the problem)</p>
  
  <p>Thanks a lot in advance.</p>
