This is the best way I have found :

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (savedInstanceState == null) {
          // Let's first dynamically add a fragment into a frame container
          getSupportFragmentManager().beginTransaction(). 
              replace(R.id.flContainer, new DemoFragment(), "SOMETAG").
              commit();
          // Now later we can lookup the fragment by tag
          DemoFragment fragmentDemo = (DemoFragment) 
              getSupportFragmentManager().findFragmentByTag("SOMETAG");
        }
    }
