我正在开发一个Android应用程序。我想在我的应用程序中显示doc，docx，xlx，xlsx文件。
在谷歌搜索后，我发现apachi POI会将这些文件转换为html。所以我已经将“poi-3.8-20120326.jar”添加到libs文件夹中并尝试构建应用程序。但我确实面临一些dalvik构建问题。
所以，我搜索了这个问题，发现POI jar支持不完全支持android的java应用程序。
我有一些用于转换ppt，pptx文件的开源。 https://github.com/qhm123/POI-Android
在这些源代码中，他们已经下载了apache poi源代码并在应用程序中添加了源代码并用它来转换ppt，pptx文件。
所以我使用了以下代码用于doc，docx页面到html。
WordToHtmlConverter.main(new String[]{"/sdcard/office/sample.doc", "/sdcard/office/sample.html"});
为此，我在我的app项目中添加了“org.apache.poi.hwpf”包。但是我得到了与上面提到的相同的dalvik构建问题。所以我无法构建应用程序。
那么如何使用apache POI做到这一点？
Dalvik错误：
