Frida as debugging tool for Android
summary
Uses Frida to attach over ADB to a rooted emulator by running frida-server in /data/local/tmp and a desktop frida client; injects a JS script using Java.perform to override a Kotlin mapper.map and a generated data class constructor, logs incoming JSON, swaps latitude and longitude in the hooked constructor, reinstantiates the Location model and hot-reloads the script so the app immediately shows the corrected scooter pins (fix confirmed). Also demonstrates SSL pinning bypass and HTTP interception capabilities.
