How can I import ripple-lib-java into Android Studio?

How can I import this library into android studio? It's not a Gradle project, nor an Eclipse project. At least that's what Android Studio tells me when I try to download the zip and import it as a module. So what should I do?

This is basically abandonware ...

Some dev happening here: https://github.com/sublimator/ripple-lib-java

I believe someone recently reported being able to use it in an android project ...

Note also, this lib is alpha, and you use at your own risk ... hasn't really seen any production usage

Alright thanks for your help!
