Bluetooth Meatball

App refactor to use fragments, a shared view model + databinding for the bluetooth socket and data, and improved logging.

Install this app on 2 phones. Pair the phones. Then select one as meatball and other as driver. You will be able to drive the ball around phone A using the accelerometer data on phone B. BUT the app will be buggy because the fragment lifecycle isnt handled well.

This is a proof of concept to get the app working with API 34. Improvements coming soon,.
