In activity OnCreate callback i added list fragment and some initial info in detail container (this is not list item details info): @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ... FragmentTransaction ft = getFragmentManager().beginTran (HowTos)
