Проблема передачи данных о намерениях камеры Android

Question

У меня есть эта проблема на Android:

Попытка вызвать виртуальный метод 'android.os.Bundle android.content.Intent.getExtras ()' для ссылки на пустой объект.

Я знаю, что делаю что-то не так, и я исследовал намерения и данные, но я очень смущен.Можете ли вы помочь мне с моим кодом?

Проблема на

Bundle extras = data.getExtras();

Я прочитал, что мне нужно передать его на onCreate, но затем я потерял все свои данные иЯ очень смущен.Вот мой код:

public class DeliveryGalleryActivity extends AppCompatActivity implements View.OnClickListener {

    private static final int REQUEST_CODE_PHOTO = 123;

    FloatingActionButton btnTakePhoto, btnSave;
    ArrayList<byte[]> images;
    ViewPager mViewPager;
    SectionsPagerAdapter adapter;

    DeliveryInfo deliveryInfo;
    String delivery = "";

    ConectivityTask connTask;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_delivery_gallery);
        connTask = new ConectivityTask(DeliveryGalleryActivity.this, this);

        mViewPager = findViewById(R.id.container);
        btnTakePhoto = findViewById(R.id.btnTakePhoto);
        btnSave = findViewById(R.id.btnSave);

        btnTakePhoto.setOnClickListener(this);
        btnSave.setOnClickListener(this);

        StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
        StrictMode.setVmPolicy(builder.build());
        images = new ArrayList<>();

        adapter = new SectionsPagerAdapter(getSupportFragmentManager());
        mViewPager.setAdapter(adapter);

        Bundle bundle = getIntent().getExtras();
        if (bundle != null) {
            delivery = bundle.getString("delivery");
            Gson gson = new Gson();
            deliveryInfo = gson.fromJson(delivery, DeliveryInfo.class);
        }

        TextView tvTitleToolbar = findViewById(R.id.tvTitle);
        if (deliveryInfo != null) {
            tvTitleToolbar.setText("Delivery " + deliveryInfo.getNumber());
            tvTitleToolbar.setPaintFlags(tvTitleToolbar.getPaintFlags()| Paint.UNDERLINE_TEXT_FLAG);
        } else {
            tvTitleToolbar.setText("Delivery");
        }

    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
