Where can be found WiFi MAC address on RPi3 with Android Things?

Question

在Raspberry Pi 3上连接WiFi（或以太网）网络之前，是否有可能使用Android Things Developer Preview 7在Raspberry Pi 3上找到WiFi（也包括以太网）MAC地址？

Answer 1

I was looking for the solution to your question. This is very important where we are using the Rasberry Pi in an location where the internet connectivity will be provided with a static ip with gateway setup inside the device or registering the device mac address on the firewall settings.

So what to do?

connect the Rasberry Pi to a wifi network where there is no static ip settings required
(Say your mobile phone's hotspot). 

Then you can find the MAC Address of the RPi from the connected devices list.

This will help you.
