It is possible to add/remove tabs in ViewPager at run time?

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    Log.v(TAG, "onCreateView");

    View rootView = inflater.inflate(R.layout.fragment_home, container, false);

    // setting up the view pager and tab layout
    mViewPager = (ViewPager) rootView.findViewById(R.id.view_pager);
    mTabLayout = (TabLayout) rootView.findViewById(R.id.tab_layout);
    PageAdapter adapter = new PageAdapter(getFragmentManager());
    mViewPager.setAdapter(adapter);

    mTabLayout.setupWithViewPager(mViewPager);
    mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(mTabLayout));

    return rootView;
}

My custom pager adapter looks like this:

public class PageAdapter extends FragmentStatePagerAdapter {

    public PageAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        return new GroupTabFragment(position);
    }

    @Override
    public CharSequence getPageTitle(int position) {
        String title = "";
        switch (position) {
            case 0:
                title = "Game";    // this is from a template, i have to
                break;             // return title dynamically
            case 1:
                title = "Movie";
                break;
        }
        return title;
    }

    @Override
    public int getCount() {
        return 2;                  // the tabs number is a subject of change
    }                              // i don't know it from the begining
}

The problem i have is that i have to add or remove a tab when a button is clicked, or something like this.

Each tab will display a classic list of objects. Thank you.
