How to get the hostname or device name of devices connected to my local network via Android?

Question

I am making an Android application that gets a list of all devices connected to my LAN (like their IP addresses and MAC addresses), something similar to what the Fing application does.

Now what I want to do is get the host names on my local network. For instance -

The IP address "192.168.1.221" returns the host name of "Sherlock".

Here, Sherlock is the device name (or host name) of my computer.

I have already tried

• InetAddress.getByName ("192.168.1.221") getHostName () ;.
• InetAddress.getByName ("192.168.1.221") getCanonicalHostName () ;.

But they continue to return the IP address itself.

Can someone help me with the right path? Perhaps there is some kind of Linux command that I could run in Runtime. All that helps.

Thanks in advance:)
