## What it is
A C library for inline hooking of native functions on 32-bit Android, supporting ARM, Thumb16, and Thumb32 instruction sets. It lets you redirect arbitrary native function calls to your own replacement functions and optionally restore the originals.

## Use cases
- hook native functions in Android apps
- intercept libc calls like puts in a native library
- instrument ARM binaries for security research
- patch function behavior at runtime on Android
- build Frida-like hooking tools for ARM32

## When to choose
- you need to hook native ARM/Thumb functions on 32-bit Android without a large framework
- you want a small C library you can build with the Android NDK
- you're doing Android security research or vulnerability analysis on ARMv7

## When to avoid
- you target 64-bit ARM (arm64) devices
- you need a maintained, actively updated hooking solution
- you prefer higher-level frameworks like Frida or Xposed
- you need to hook very short functions, which inline hooking cannot handle

## Facets
- artifact type: library
- maturity: maintenance
- function: reverse-engineering, security, developer-tools
- domain: security, reverse-engineering, android-tools, developer-tools
- platform: cpp, c, cli
