## What it is
ByteHook is a production-grade Android PLT hook library written in C, supporting armeabi-v7a, arm64-v8a, x86, and x86_64. It lets native code intercept calls to functions in dynamic libraries via GOT/PLT hooking, with automatic handling of recursive calls and newly loaded libraries.

## Use cases
- hook native functions in Android dynamic libraries
- intercept libc calls in an Android app at runtime
- monitor or replace native library function calls on Android
- patch native behavior without modifying library source
- debug native crashes with backtrace unwinding in proxy functions
- hook all or selected .so libraries in an Android process

## When to choose
- you need stable, production-ready PLT/GOT hooking on Android 4.1+
- you need multi-architecture support including x86 and x86_64
- you want automatic hooking of newly loaded dynamic libraries
- you need to hook the same function from multiple callers safely

## When to avoid
- you need inline hooking of arbitrary code addresses - use ByteDance's shadowhook instead
- you target platforms other than Android
- you need Java-level method hooking rather than native PLT hooking
