# Sandwitcher

> Sandwitcher instruments Java and Kotlin method calls in Android apps by replacing ART method entry points with a trampoline through Pine and LSPlant. Its AAR exposes callbacks before and after the original call to inspect or change arguments and results and inspect thrown exceptions; it also includes a demo application.
