如何在Android中扫描局域网中其他设备的MAC地址？

Question

有没有一种清晰的方法并且可以轻松实现以扫描本地网络以获取连接到我在android中的WiFi网络的设备的MAC地址？

I don't believe that Android will allow you access to raw sockets in order to send ARP requests, so probably the easiest way is to sand some traffic (this can be any kind of traffic) to all IP addresses in the network forcing the phone to get the MAC addresses for all IPs via ARP. Then you can read the ARP cache ( /proc/net/arp ) and get the IP to MAC mappings.
