Uri.getPath () является нулевым

Question

Я пытаюсь автоматически повернуть изображения из намерения системной галереи, но ExifInterface не может получить путь из изображения URI. В этой строке происходит сбой: img

Создание намерения галереи:

Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);

        startActivityForResult(Intent.createChooser(intent, getString(R.string.choose_image)), 1);

onActivityResult:

    @Override
    protected void onActivityResult(int RequestCode, int ResultCode, Intent I) {
        super.onActivityResult(RequestCode, ResultCode, I);

        if (RequestCode == 1 && ResultCode == RESULT_OK && I != null && I.getData() != null) {
            uri = I.getData();
            try {
                ImageBitmap = handleSamplingAndRotationBitmap(Gallery.this, uri);
            } catch (IOException e) {
                e.printStackTrace();
            }
                SelectedImage.setImageBitmap(ImageBitmap);
                detectImage();
        } else {
            Intent intent = new Intent(this, MainActivity.class);
            startActivity(intent);
        }
    }

Этот поворот был полностью скопирован с другого вопроса, где он работает. Так что я не знаю, что не так. У Ури есть путь внутрь, но getPath () не может его найти ...
