title: New LifecycleFragment component and old FragmentTransaction
body: <p>I am trying to apply new <code>LifecycleFragment</code> in my Android application: </p>
  
  <pre><code>        FragmentManager fragmentManager = getFragmentManager();
          FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
          fragmentTransaction.replace(R.id.fragmentContainer, new CustomBlockUrlProviderFragment());
          fragmentTransaction.addToBackStack("manage_custom_url_providers");
          fragmentTransaction.commit();
  </code></pre>
  
  <p><code>fragmentTransaction.replace(R.id.fragmentContainer, new CustomBlockUrlProviderFragment());</code> and I am getting error on this line. Saying that 2nd argument should be <code>Fragment</code>. </p>
  
  <p>How to make it work?  </p>
