[android-developers] Adding fragments to backstack in different transactions

Hello,

I have a framelayout where I am adding a listfragment and adding it to backstack. If user selects an item in that list, I start a new transaction and replace the last fragment with a new one. But when I press back button, I dont see my first list fragment, rather I see the original splash screen.

Do I have to replace fragments in same transactions to be able to navigate back to last fragment?

Here is my code:

//Adding first fragment:

private void addRouteCategoryFragment(){

        FragmentManager fm       = getSupportFragmentManager();

        FragmentTransaction ft = fm.beginTransaction();

        ft=fm.beginTransaction();

        ft.add(R.id.fragment_content, new RouteCategoryFragment(),ROUTE_CATEGORY_TAG);

        ft.addToBackStack(null);

        ft.commit();

    }

//Once user selects and item in RouteCategoryFragment, I replace it with other fragment-

private void handleRuralRoutesClick(){

        FragmentManager fm       = getSupportFragmentManager();

        FragmentTransaction ft = fm.beginTransaction();

        ft.replace(R.id.fragment_content, new CountyListFragment(),COUNTY_TAG);

        ft.addToBackStack(null);

        ft.commit();

    }

Thanks
