This is an old question but my answer might help someone.

Why not checking if the fragment is in the stack and pop it? This way you wouldn't have to worry with back stack size (unless you have a lot of fragments).

    String backStateName = fragment.getClass().getName();
    boolean fragmentPopped = false;
    try {
        // true if fragment is in the stack
        fragmentPopped = fragmentManager.popBackStackImmediate(backStateName, 0);
    } catch (Exception e) {
        e.printStackTrace();
    }

    FragmentTransaction ft = fragmentManager.beginTransaction();

    if ( !fragmentPopped ) { //fragment not in back stack, add it...            
        ft.setTransition( FragmentTransaction.TRANSIT_FRAGMENT_FADE );
        ft.replace(R.id.main, fragment);
        ft.addToBackStack( backStateName );

        try {
            ft.commit();
        } catch (Exception e) {
            e.printStackTrace();
        }           
    }
