Android ScanLibrary

Question

Я пытаюсь реализовать функцию сканирования в своем приложении, для этого я использую Android обрезать изображение как библиотеку сканирования camscanner , но когда я щелкаю изображение с камеры, ничего не происходит. Часть кадрирования не идет.

вот мой полный проект https://drive.google.com/open?id=1pKTq0QwxuN1jy9Q1eFSQyr-TUEHFKHtQ

Я получаю ошибку ниже.

Мое устройство Android 10. Может ли кто-нибудь помочь вам, если вы использовали эту библиотеку.
