title: onBackPressed() and Fragments
body: <p>I am trying to use onBackPressed() in my Fragment so that I can allow the user to roll back in a pile of fragments he navigated in my app.</p>
  
  <p>The problem is that, when I add the method below to my Fragment, it gives me the error: <code>Method does not override method from its superclass</code>.</p>
  
  <pre><code>@Override
  public void onBackPressed() {
  
      android.support.v4.app.FragmentManager fragmentManager = getFragmentManager();
      fragmentManager.popBackStack();
  
  }
  </code></pre>
  
  <p>Would you know why?</p>
  
  <p>Thanks!</p>
  
  <p>Here goes the entire Fragment:</p>
