Я пытаюсь использовать библиотеку Docx4j , чтобы прочитать содержимое файлов Word, выбранных пользователем (пытался следовать коду в https://github.com/plutext/Docx4j4Android4). Однако, При чтении файла MS Word появляется следующая ошибка:
W/System.err: log4j:ERROR Could not parse url [jar:file:/data/app/com.example.diffcheckertest-8hLouozp5QPE6U8NaxyKYA==/base.apk!/log4j.xml].
javax.xml.parsers.ParserConfigurationException: No validating DocumentBuilder implementation available

Ниже приведена строка кода в MainActivity.kt, где я открываю документ MS Word и где происходит ошибка (я импортировал файл необходимые утилиты):
