Question

This maybe a noob question but please help me.
I found a library called Graphview for android and I would like to customize a bit and use it in my project. I know .jar is a zip file so after I extracted it I saw 2 folders, one contains some .class files and .java files, My question is, do I just need to change the codes I want in .java files? How about those .class files? And How do I put all the changed files back to recreate a new .jar file so I can use it in my project?

Here is the library from Github :https://github.com/jjoe64/GraphView/downloads

I would

• fork the original git library.
• modify it.
• build it.
• consider providing your improvement to the original build.

I wouldn’t try hacking the existing library even though you can do this if you really have to (because you have no access to the original build)
