I am writing an application to open and read a .dwg file in android os. the IDE I am using is eclipse

I wanted to know if I had the source code of a reader or a . har file, then how to include it in my application.

You have to convert it (dwg/dfx) into pdf and then use a pdf viewer to view it in android
