WiFiCommunicator for NXT and EV3

[mandaiy]

Summary

NXT and EV3 have wifi communication function.
But this app does not support WiFi connecting function.

There seem to be some demand for wifi communication between this app and robots.
So in this issue I leave some notes for implementing the function.

What we should consider

We have to consider how the machine to be connected is specified by this app.
One possible and apparently easiest way is to input the machine's IP address directly by a user.
We have to survey whether it is possible to scan machines.

What we should implement

We have to implement WiFiCommunicator, a concrete class of ICommunicator and the counterpart of BluetoothCommunicator.
Also WiFiMachineSelectFragment and its related classes are needed to be implemented.

Where we should modify

We have to modify some bluetooth-dependent code in

• ExecutionActivity
• ProgrammingActivity

The other classes seem not to have to be modified.
