How to detect all the Devices connected in a WiFi network from Android App

java monitoring networking hardware android

I am developing an app in which I need to scans WiFi network and display the list of all connected devices.

Allow a use to tap on a device and the app should show all the hardware info of that particular device. Here by hardware I mean - RAM, Storage Media, Storage Capacity, Device Name, Device IP address, etc.

Now this device can be anything like xbox, a laptop with Linux/Windows, mobile phone like iPhone or any Andorid based smart phone or even a printer.

How can I scans WiFi network and query/detect all the devices attached to it?

What are the protocols that I need to use to get list of hardware in a particular device irrespective of the OS running on it?


Check requestPeers of WifiP2pManager

As per documents it seeks PeerListListener which returns WifiP2pDeviceList carrying list of WifiP2pDevice which carries deviceAddress, deviceName, primaryDeviceType, secondaryDeviceType, status and other attributes.


Maybe the Network Discovery github project could help you. It lists all users connected to WiFi with IP and MAC addresses and gathers even some information like open ports, device name, ping, etc. Hope it helps
