How would this be linked in Android Studio?

I am doing a project which needs butterworth filtering, and can't seem to find libraries for DSP in android.
Do you have any directions as to how I can use this in my project?

See the readme. Just install it with maven, then add the dependency to android studio and off you go.
Check out AttysECG for example how it's done.
