I managed to find the G4 android driver that you mentioned at the bottom of this page under the "Supported OS" section;
Now that I have those what would you say the steps are exactly again?
To give you an idea of what the project looks like thus far here is a video link. I hope it sparks your interest and I'm prsenting it in Portland Oregon in a little over a month so hoping to have version 2 prototype done!
I'll be releasing a new video going in depth about the UI I've made and other features here in the next few weeks.
