android - FragmentPagerAdapter getItem is not called

Question

I am not able to reuse fragment in FragmentPagerAdapter.. Using destroyItem() method, It is deleting the fragment but still does not called getItem() again..There are just 2-3 Images so I am using FragmentPagerAdapter Instead of FragmentStatePagerAdapter..

public class ExamplePagerAdapter extends FragmentPagerAdapter {

    ArrayList < String > urls;
    int size = 0;
    public ExamplePagerAdapter(FragmentManager fm, ArrayList < String > res) {
        super(fm);
        urls = res;
        size = urls.size();
    }

    @Override
    public int getCount() {
        if (urls == null) {
            return 0;
        } else {
            return size;
        }

    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        FragmentManager manager = ((Fragment) object).getFragmentManager();
        FragmentTransaction trans = manager.beginTransaction();
        trans.remove((Fragment) object);
        trans.commit();
    }

    @Override
    public Fragment getItem(int position) {

        Fragment fragment = new FloorPlanFragment();
        Bundle b = new Bundle();
        b.putInt("p", position);
        b.putString("image", urls.get(position));
        Log.i("image", "" + urls.get(position));
        fragment.setArguments(b);
        return fragment;
    }
}

And In FragmentActivity,

pager.setAdapter(new ExamplePagerAdapter(getSupportFragmentManager(), res2));

KISS Answer:

Simple use FragmentStatePagerAdapter instead of FragmentPagerAdapter.

I got the answer.. Firstly I thought to delete this question as I am doing a very silly mistake but this answer will help someone who is facing the same problem that Instead of FragmentPagerAdapter, use FragmentStatePagerAdapter.

As @BlackHatSamurai mentioned in the comment:

The reason this works is because FragmentStatePagerAdapter destroys as Fragments that aren't being used. FragmentPagerAdapter does not.
