theoretically this is possible, as java is cross-platform (regardless of Linux or not), and so is libusb, so no 'hacking' really required, just some work
you would need a specific android build, including build tools (for compiling patches), and also it would have to be for the correct architecture (libusb). ... and your device would have to be powerful enough, both cpu, gpu and enough memory.
(perhaps worth baring in mind there, a rPI3, doesn't fill the requirements)
also currently the editor kind of works with touchscreens, but its not ideal, really we need to move to javaFX to support this better.
I don't have an android devices (except my tv), not any desire... but would be interested to hear if someone gives it a go.
