Set static ip to ethernet in android

Question

I have ethernet connected to my android board. I want to manually set IP from code. I was able to set IP address for WIFI. I have looked into following links for ethernet

Assign static IP to ethernet card from OTG So far I have not found how to set static IP to ethernet via android code.

Did you find any solution to this without running `su -c` commands on the phone? — Majoren, Jun 26 '19 at 14:25

You may need to create /data/misc/ethernet/ipconfig.txt file to configure static IP address.
As you successfully configured static IP address for WiFi already,
I think /data/misc/wifi/ipconfig.txt was also created and it will be valid for Ethernet config, too.
Please refer to following links for file path and data format.
EthernetConfigStore.java
IpConfigStore.java

together with this tool this seems to be a great answer https://github.com/jhswartz/ipconfigstore – Andreas Schuldei Jul 15 '20 at 14:38
There is a much simpler way of doing this by GUI, i just don't remember the steps, and i need this for a client... damm friday XD – Juan Ignacio Avendaño Huergo Jun 10 '22 at 12:11

I was able to set Ip to Ethernet connection as follows. I was using Allwinner A31s android board.

String command1 = "su -c ifconfig eth0 "
                        + terminalIpAddressString+" netmask "
                        + subnetMaskAddressString
                        +" up";
                String command2 = "route add default gw "
                        + gatewayAddressString+" dev eth0";



                String command3 = "mount -o remount,rw /system";
                String command4 = "echo \"su -c ifconfig eth0 "
                        +terminalIpAddressString+" netmask "
                        +subnetMaskAddressString+" up;" +
                        "route add default gw "
                        +gatewayAddressString
                        +" dev eth0\" > /system/bin/preinstall.sh";

                String command5 = "busybox sed -i 's/su -c ifconfig eth0 "
                        +terminalIpAddressString
                        +" netmask "+subnetMaskAddressString+" up;"
                        +"route add default gw 172.19.10.2 dev eth0"
                        + "/su -c ifconfig eth0 "+terminalIpAddressString
                        +" netmask "+subnetMaskAddressString+" up;"
                        +"route add default gw "+gatewayAddressString
                        +" dev eth0/g' /system/bin/preinstall.sh";

This is a poor answer, in that the OP sought to do this via Android code, not commands to the underlying operating system. — Joseph Van Riper, Jun 26 '23 at 09:57
