После дополнительного поиска я нашел какой-то более новый код, который я смог отредактировать, чтобы он заработал для меня, где я получил диалоговое окно с вопросом, хочу ли я использовать камеру или выбрать файл.
Редактироватьимя пакета и URL, соответствующий вашему проекту. Я оставил все разделы, которые были закомментированы в коде, который я скопировал в коде ниже, но я буду удалять большинство из них в моем собственном проекте.
Надеюсь, это поможет кому-то еще.
Я не внес изменений в свой HTML или файл AndroidManifest.xml.
