Getting list of available WiFi networks

[Lucas 'Ktulu789']

Is there a way to get the array of "visible" WiFi netwworks?

I want to silence the phone when I'm on the meetings room. There are a couple of neighboring WiFi networks that are not visible from my office so I can use that as the trigger. But I don't know how to get a list/array of available networks.

Any help will be very appreciated! Thanks in advance!
