This is a little project that is able to get the current network's gateway IP on Termux, done as a demonstration. This is necessary because Android 14+ restricts access to /proc/net, making it impossible to obtain the current gateway IP through conventional means.

To build on device, you'll need to setup sdkmanager and set your ANDROID_HOME environment variable, and add android.aapt2FromMavenOverride=/data/data/com.termux/files/usr/bin/aapt2 to your ~/.gradle/gradle.properties.

Before executing ./command/run, you'll need to run gradle extractDexDebug or gradle build (see above about building on device). It's not actually necessary to extract the dex file to run it, you can just point the script to the apk instead (by replacing -cp $DEX_FILE with -cp [apk file here] in the final line of the script, and ensuring that the apk has it's mode set to 0400).
