问题
I am developing an android application. In which I want to show the doc, docx, xlx, xlsx files in my application.
After searched in google, I came to know that the apachi POI will convert these files into html. So that I have added the "poi-3.8-20120326.jar" into the libs folder and try to build the app. But I did face some dalvik build issue.
So, I searched about this issue and found that the POI jar is supporting for java apps not fully supported for android.
I got some opensource for converting ppt, pptx files. https://github.com/qhm123/POI-Android
In these source code, they have downloaded the apache poi source code and added the source in the app and used it to convert the ppt, pptx files.
So I have used the following code for doc, docx pages to html.
WordToHtmlConverter.main(new String[]{"/sdcard/office/sample.doc", "/sdcard/office/sample.html"});
For this I have added the "org.apache.poi.hwpf" package in my app project. But I got the same dalvik build issue what I mentioned above. So I couldn't build the app.
So how can I do this using apache POI?
Dalvik Error:
