Installing APKs into nethunter?

I'm trying to get an APK installed that provides an API in python for accessing the GPS coordinates of my Android. I downloaded and installed it, but it doesn't seem to be available in my nethunter terminal. How can I install it such that it will be accessible by the nethunter terminal?

I suspect you're doing something wrong. You install APK's on NetHunter just as you would on any android device, no special treatment required.
