trying to make app that use Naviagtion Components with two simple screens managed with Navigation Graph, one of witch is:

MainFragment:

public class MainFragment extends Fragment {

private MainViewModel mViewModel;

public static MainFragment newInstance() {
    return new MainFragment();
}

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container,
                         @Nullable Bundle savedInstanceState) {
    return inflater.inflate(R.layout.main_fragment, container, false);
}

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    mViewModel = new ViewModelProvider(this).get(MainViewModel.class);

    Button button = getView().findViewById(R.id.button);

    button.setOnClickListener(Navigation.createNavigateOnClickListener(R.id.mainToSecond,null));

    // TODO: Use the ViewModel
}

}

And 2nd screen:

public class SecondFragment extends Fragment {


public interface OnFragmentInteractionListener {
    // TODO: Update argument type and name
    void onFragmentInteraction(Uri uri);
}

// TODO: Rename parameter arguments, choose names that match
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";

// TODO: Rename and change types of parameters
private String mParam1;
private String mParam2;


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

/**
 * Use this factory method to create a new instance of
 * this fragment using the provided parameters.
 *
 * @param param1 Parameter 1.
 * @param param2 Parameter 2.
 * @return A new instance of fragment SecondFragment.
 */
// TODO: Rename and change types and number of parameters
public static SecondFragment newInstance(String param1, String param2) {
    SecondFragment fragment = new SecondFragment();
    Bundle args = new Bundle();
    args.putString(ARG_PARAM1, param1);
    args.putString(ARG_PARAM2, param2);
    fragment.setArguments(args);
    return fragment;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (getArguments() != null) {
        mParam1 = getArguments().getString(ARG_PARAM1);
        mParam2 = getArguments().getString(ARG_PARAM2);
    }
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.fragment_second, container, false);
}

}

My "Navigation Host" is MainActivity class:

public class MainActivity extends AppCompatActivity implements
    SecondFragment.OnFragmentInteractionListener {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_activity);
}
@Override
public void onFragmentInteraction(Uri uri){}}

While running up on emulator, Gradle showing no erros but app doesn't launch. Here's error that I've got.

 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.navigationdemo/com.example.navigationdemo.ui.main.MainActivity}: android.view.InflateException: Binary XML file line #10

Replace your full code in main_activity with this:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".ui.main.MainActivity">

    <androidx.fragment.app.FragmentContainerView
        android:id="@+id/demo_nav_host_fragment"
        android:name="androidx.navigation.fragment.NavHostFragment"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"

        app:defaultNavHost="true"
        app:navGraph="@navigation/navigation_graph" />

</androidx.constraintlayout.widget.ConstraintLayout>
