Is there a way to build this package into a java module or lib?

[swuqi]

Firstly I tried to get all related Java files from web and used Android Studio to build it into a Java lib. But finally I found that I couldn't get some dependencies.
Then I built an Ubuntu VM and ran ant command to build the project. It didn't generate any Java lib either.
I wonder there is a way to build a Java module so we can use it in other Apps.

Thank you.
