## What it is
Hunter is a framework for developing Android Gradle plugins that manipulate bytecode using ASM and the modern AGP Instrumentation API. It ships with ready-made plugins (e.g., OkHttp hacking, method timing) and supports incremental, concurrent builds.

## Use cases
- develop a custom android gradle plugin to transform bytecode
- inject a global interceptor into all OkHttpClients including third-party libraries
- time ui-thread methods and dump slow method traces
- monitor or enhance third-party dependencies at build time
- instrument android framework classes without slowing builds

## When to choose
- you need bytecode weaving in an Android build with AGP 7.4-8.7+
- you want incremental, parallel instrumentation with minimal build-time overhead
- you need to patch behavior of libraries you don't control, like OkHttp

## When to avoid
- your project still uses AGP 4.x with the legacy Transform API (use Hunter 1.2.x)
- you need non-Android JVM bytecode tooling
- you want a no-code runtime-only solution rather than build-time transformation
