In an activity, on click of a button I raise a fragment. This fragment also has button inside it. Now on click of this fragment button 'onCancelClick', I want to startActivity
named as 'Titles.class'. There is no error in the code but I get the message that 'apps has stopped working'.

public class titles_new_fragment extends Fragment {
  @Override
    public View onCreateView( LayoutInflater inflator, ViewGroup container,Bundle  savedInstanceState) {
      return inflator.inflate(R.layout.fragment_titles_new_layout,container,false);
    }

    private void onCancelClick(View v)
    {
      Intent intent = new Intent( getActivity(), Titles.class);
      startActivity(intent);
    }
}
