Assign static IP to ethernet card from OTG

Question

I would like to assign a static IP to an ethernet card, connected to the Android device via OTG cable. It should be done programmatically, but I can't find any reference regarding ethernet cards in android.

Any ideas?

Thank you

On a stock, non-rooted Android device, there is unlikely to be any support for a USB ethernet adapter, so I expect you will have to implement the entire network stack in userspace within your application, coding against the Android USB host APIs. That's going to be a huge project - but if you get it done, setting a static IP will be a fairly trivial task. — Chris Stratton, May 09 '14 at 17:59

If its a rooted device you can try with this

Process process = Runtime.getRuntime().exec(new String[] { "su", "-c", "netcfg eth0 192.168.0.123"});
process.waitFor();

And also you can use ifconfig instead of netcfg.

Thanks for your answer but the device should not be rooted; – Alqueraf May 05 '14 at 09:19
Do your device have ethernet port ?? – Charan Pai May 05 '14 at 09:28
No, just a mini-usb port where I connect an external ethernet card – Alqueraf May 05 '14 at 09:30
That need some specific drivers installed on device. – Charan Pai May 05 '14 at 09:33
I tried this solution for rooted device, but its not working. Can someone point me how to do it in rooted device – Tushar Thakur Sep 29 '17 at 06:03
@CharanPai can you help me out here? – Tushar Thakur Oct 09 '17 at 05:53
I am using a rooted device, running the suggested command. Command successfully running without any error, but IP is not changed in the device. – GNK Nov 07 '22 at 07:41
