Я разрабатываю приложение для Android. В котором я хочу показать файлы doc, docx, xlx, xlsx в моем приложении.

После поиска в Google я узнал, что apachi POI преобразует эти файлы в html. Так что я добавил"Пои-3.8-20120326.jar" в папку libs и попробуйте собрать приложение. Но я столкнулся с проблемой сборки далвиков.

Итак, я искал об этой проблеме и обнаружил, что jar POI поддерживает java-приложения, не полностью поддерживаемые для Android.

У меня есть некоторые с открытым исходным кодом для преобразования файлов PPT, PPTX.https://github.com/qhm123/POI-Android

В этом исходном коде они загрузили исходный код apache poi, добавили исходный код в приложение и использовали его для преобразования файлов ppt, pptx.

Поэтому я использовал следующий код для документов docx и страниц html.

WordToHtmlConverter.main(new String[]{"/sdcard/office/sample.doc", "/sdcard/office/sample.html"});

Для этого я добавил пакет «org.apache.poi.hwpf» в свой проект приложения. Но я получил ту же проблему сборки dalvik, о которой упоминал выше. Поэтому я не смог собрать приложение.

Итак, как я могу сделать это с помощью Apache POI?

(org.apache.log4j.chainsaw.ControlPanel$1) that doesn't come with an
