AoA connection is done now, but in our actual code, I recommend we do not use the near field communication directly from Arduino to Android. I will explain why tomorrow. Then I will remove the unneeded AoA direct communication source code and leave just the code for getting subnet url. So be informed that this is not the final code we will actually use. It is just an example for AoA. Will correct the code tomorrow and there seems something to update for the Arduino sketch and will do it tomorrow. Nice night~
