Android java.lang.IllegalArgumentException: ID does not reference a View inside this Activity

Question

Dzień dobry.

Utworzyłem program w javie, zainstalowany w windows działa, teraz chcę przenieść go na androida. Mimo, że w studio android stworzony kod nie pokazuje błędów, to uruchomienie aplikacji jest przerywane i nie mam pojęcia co z tym zrobić. Od razu pragnę przekazać, że programowaniem zajmuję się od dwóch miesięcy dlatego proszę o wyrozumiałość :) Poniżej mój kod androida i dalej błąd wyświetlany po uruchomieniu:

  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        com.example.programkalkulatorpiekarniczy.databinding.ActivityMainBinding binding = ActivityMainBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());
        setContentView(R.layout.activity_main);
        poleNumeruPieczywa = (EditText) findViewById(R.id.poleNumeruPieczywa);
        poleLiczbySztuk = (EditText) findViewById(R.id.poleLiczbySztuk);
        poleTekstowe = (TextView) findViewById(R.id.poleTekstowe);
        Button przyciskWyboru = (Button) findViewById(R.id.przyciskWyboru);
        przyciskWyboru.setOnClickListener(view -> bakeCalc());

        setSupportActionBar(binding.toolbar);

        NavController navController;
        navController = Navigation.findNavController(this, R.id.nav_host_fragment_content_main);
        appBarConfiguration = new AppBarConfiguration.Builder(navController.getGraph()).build();
        NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);

        binding.fab.setOnClickListener(view -> Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                .setAction("Action", null).show());
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @Override
    public boolean onSupportNavigateUp() {
        NavController navController = findNavController(this, R.id.nav_host_fragment_content_main);
        return NavigationUI.navigateUp(navController, appBarConfiguration)
                || super.onSupportNavigateUp();
    }
}
