Android - docx4j build issue

Question

I am developing an android application. In which I need to show the docx, xlsx files inside my application. I have searched in the internet and found docx4j

Answer 1

Finally I found the solution. I did add all the jars what they given in the github. So that I got the above exception.

Now I removed the "serializer-2.7.1.jar" from the workspace and then build the app. I can convert the docx to html without build issue. It is working fine now.
