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 will convert docx, xlsx files to html (or) pdf. So that I am planning to show the html return from the docx4j in the webview.
So that I have downloaded the source from github and tried to run the sample. I made changes in eclipse.ini file as given in the link as well.
But, I couldn't execute the application. When I run the app, I am getting the following exception.
[2014-11-24 17:19:34 - AndroidDocxToHtml-master] Conversion to Dalvik format failed with error 1
The detailed log :
[2014-11-24 17:19:34 - AndroidDocxToHtml-master] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.apache.xml.serializer.SecuritySupport12$8) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

I have added the libs only one time in the app.
What may be the issue. Can anyone help me to fix this?
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.
