(Android) Transformers - Bytecode in Disguise!

on YouTube ↗34m

" summary

A talk explains how Firebase Performance Monitoring detects and reports HTTP traffic by rewriting app classes at build time using the Android Transform API inside a Gradle plugin. The plugin performs bytecode manipulation to rewrite call sites and insert runtime hooks for three HTTP stacks (URLConnection, Apache, OkHttp), allowing interception and measurement of real network traffic without a runtime network-listening agent.
