Custom Android App - Simple grid of toggle switches that send x,y coordinates of the switch closed/opened via bluetooth to a connected Bluetooth device.

I need a custom program that will translate a grid of toggle switches/ check boxes on the app to an x,y coordinate which will be sent to a connected BT device. The app needs to be able to pare to a blue tooth device (which will be an Arduino BT Sheild) The app will send x,y coordinates of the rid position of the toggled button (check-box or toggle switch) to the connected Blue tooth device. 1) The app should reset all buttons to off ( normal sate) when re-stared. 2) Should have a facility to connect to a blue tooth device. 3) A grid of 11 x 11 buttons/switches/toggels should be visible to the user. I'd like all the code, such that I may modify the program at will. Attached is an image of what I think it would look like:
