App crashes on passing data from activity to fragment

I was working on passing the recyclerview item from activity to fragment and I found Bundle useful for that but in my fragment when I try to retrieve the data then the app crashes, so how do I fix it?

This is my activity file code for sending the data

            Bundle bundle = new Bundle();
            bundle.putString("title", title.getText().toString());
            bundle.putString("description", 
            description.getText().toString());
            bundle.putString("date", date.getText().toString());

            UpdatesActivity updatesActivity = new UpdatesActivity();
            updatesActivity.setArguments(bundle);

This is my fragment activity(named UpdatesActivity)

private List<Info> infoList = new ArrayList<>();
private InfoAdapter mAdapter;
private Button btnLogOut;
private FirebaseAuth firebaseAuth;
private String title, description, date;

public UpdatesActivity() {
    // Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_updates, container, false);

    RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);

    title = getArguments().getString("title");
    description = getArguments().getString("description");
    date = getArguments().getString("date");

    mAdapter = new InfoAdapter(infoList);
    recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
    recyclerView.setItemAnimator(new DefaultItemAnimator());
    recyclerView.addItemDecoration(new DividerItemDecoration(getActivity(), LinearLayoutManager.VERTICAL));
    recyclerView.setAdapter(mAdapter);

    return view;
    }
}

Now when I remove the lines for retrieving the title, description and date then the app works fine but on adding them the app crashes.

you can use from this method 

 private void loadFragment(Fragment fragment) {
        Bundle bundle = new Bundle();
        bundle.putString("title", title.getText().toString());
        bundle.putString("description",
                description.getText().toString());
        bundle.putString("date", date.getText().toString());
        fragment.setArguments(bundle);
        FragmentManager fm = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fm.beginTransaction();
        fragmentTransaction.replace(R.id.fragmentContainer, fragment);
        fragmentTransaction.commit(); // save the changes

    }
