Cannot get support FragmentManager inside Fragment - ViewPager inside Fragment

I am trying to create activity with NavigationDrawer, and inside one Fragment, i want to place ViewPager. The problem is, when i am trying to create new SectionPagerAdapter (class extending FragmentPagerAdapter), i cant get proper FragmentManager for constructor.

There is code of onCreateView of navDrawer fragment where i want to place ViewPager:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.layout_anime, container, false);

    final ActionBar actionBar = getActivity().getActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    //There is problem:
    mSectionsPagerAdapter = new SectionsPagerAdapter(getChildFragmentManager());
    mViewPager = (ViewPager) getActivity().findViewById(R.id.pager);
    mViewPager.setAdapter(mSectionsPagerAdapter);

    mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
        @Override
        public void onPageSelected(int position) {
            actionBar.setSelectedNavigationItem(position);
        }
    });

    for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {
        actionBar.addTab(actionBar.newTab()
                .setText(mSectionsPagerAdapter.getPageTitle(i))
                .setTabListener(this));
    }

    return rootView;
}

SectionPagerAdapter class:

public class SectionsPagerAdapter extends FragmentPagerAdapter {

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

    @Override
    public android.support.v4.app.Fragment getItem(int position) {
        android.support.v4.app.Fragment fragment = new DummySectionFragment();
        Bundle args = new Bundle();
        args.putInt(DummySectionFragment.ARG_SECTION_NUMBER, position + 1);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public int getCount() {
        return 3;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        Locale l = Locale.getDefault();
        switch (position) {
            case 0:
                return "Section 1".toUpperCase();
            case 1:
                return "Section 2".toUpperCase();
            case 2:
                return "Section 3".toUpperCase();
        }
        return null;
    }
}

and DummySectionFragment:

    public static class DummySectionFragment extends android.support.v4.app.Fragment {
        public static final String ARG_SECTION_NUMBER = "section+number";

        public DummySectionFragment() {
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

            View rootView = inflater.inflate(R.layout.layout_anime, container, false);
            ListView listView = (ListView) 

//My code here - http request and listView creating

        }

    }

Now i have an error when calling getChuldFragmentManager(), which says that android.app.FragmentManager cannot be applied to android.support.v4.app.FragmentManager

SOLVED I was extending android.app.Fragment instead of android.support.v4.app.Fragment in my class

According to this

android.support.v4.FragmentManager cannot be applied to android.app.FragmentManager

you are using android.app.FragmentManager in SectionsPagerAdapter class. Change it to android.support.v4.FragmentManager.

Remove your import import android.app.FragmentManager; and add this

import android.support.v4.app.FragmentManager;
