如何查找连接到Wifi AP的用户数（Android）

Question

I wanted to know how I could return the MAC addresses connected to a router so I could get a count of how many users are connected to a specific AP? I've been doing research on this but I haven't found too much help. The one thing I did find is that you can get this information from parsing the /proc/net/arp file, however, from my understanding for this to work your phone must be acting as an AP itself. I am trying to write an Android app that is able to return the number of users on a specific router. This is part of a project for school. The app is just for learning purposes since I will be using it to scan routers that are not my own.

You have your answer if your Android is the AP. But if the AP is a router outside your own device and control this will mean connecting via a admin API to get at the router's information. As far as I know there are no standards for this kind of API so might be stuck doing interfaces to a few major manufacturers and models via whatever methods they may offer, if any. And don't forget that you will still need admin access (admin user id/password) to the router.
