Re: Did you knew ?
I forgot to mention: Whilst "cat /proc/net/arp" will give you the mac of the router, to find your own mac, again, WITHOUT any special privileges, open a socket to AF_NETLINK, or from the command line:
iplink
If that doesn't exist, download a "busybox" binary, and type "busybox iplink"
So there you have it: MACs of both the router and your own device. - without permissions - at least as far as Lollipop.
As I said, look at android from a Linux point of view, rather than from an android point of view - you'll be surprised.
