What I have tried:

Fragment fragment= new FirstFragment();
android.app.FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.fragment_container, fragment); // fragmen container id in first parameter is the container(Main layout id) of Activity
transaction.addToBackStack(null); // this will manage backstack
transaction.commit();
