Dynamically adding/removing pages from FragmentStatePagerAdapter

I was looking at the example of the FragmentStatePagerAdapter at http://developer.android.com/reference/android/support/v4/app/FragmentStatePagerAdapter.html

public static class MyAdapter extends FragmentStatePagerAdapter {
    public MyAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public int getCount() {
        return NUM_ITEMS;
    }

    @Override
    public Fragment getItem(int position) {
        return ArrayListFragment.newInstance(position);
    }
}

I've also looked around at other posts in stackoverflow, but I am still unsure as to how to add/remove pages from the fragmentStatePagerAdapter, and also how exactly the getItem method is called. So if I were looking to add a method to MyAdapter to add pages, how would that be done? Or is that not the standard way of adding pages? Any information is appreciated.

After adding the new item you'll need to call myAdapter.notifyDataSetChanged();

Also, it seems you use a const for the number or items NUM_ITEMS, you'll need to change that to something dynamic you can change.
