## What it is
Shadowhook is an Android inline hook library written in C, supporting armeabi-v7a (thumb/arm32) and arm64-v8a architectures on Android 4.1 through 17. It provides stable, production-ready hooking and interception of native functions, with features like automatic handling of newly loaded ELFs, recursive call prevention, and unwind compatibility.

## Use cases
- hook native functions in Android apps
- intercept native library calls at runtime
- instrument native code for debugging or monitoring
- hook functions by address or by library name plus symbol name
- bypass linker namespace restrictions to resolve symbols
- monitor .init and .fini execution of newly loaded ELFs

## When to choose
- you need stable inline hooking of native ARM/ARM64 code in production Android apps
- you need broad Android version compatibility from 4.1 onward
- you want automatic hooking of functions in newly loaded ELFs
- you need to intercept native calls without modifying source code

## When to avoid
- you need PLT/GOT hooking instead of inline hooking (use ByteHook)
- you target non-ARM architectures such as x86
- you need hooking on platforms other than Android
- your project requires a license other than MIT
