Я пытаюсь прочитать данные из файла xlsx и загрузить их в Firebase Firestore. Я успешно прочитал данные из файла xls и загрузил его.
При использовании реализации "org.apache.poi: poi-ooxml: $ poi_version" приложение успешно создается, но при запуске вылетает, что приводит к исключению времени выполнения: "невозможно создать экземпляр appComponentFactory" вместе с "невозможно получить поставщик com. google.firebase.provider.FirebaseInitProvider».

Thisкод работал нормально только с реализацией org.apache.poi: poi для книг xls. Но это нужно обновить, чтобы прочитать xlsx, так как я должен загружать изображения в хранилище Firebase после чтения их из файла Excel.
