## What it is
ADBI is a dynamic binary instrumentation toolkit for Android ARM and Thumb binaries, based on library injection and inline hooking of function entry points. It consists of a hijack injection tool and a base hooking library used to build custom instrumentation libraries.

## Use cases
- hook native functions in Android apps
- instrument Android ARM binaries to log API calls
- inject a shared library into a running Android process
- trace system calls like epoll_wait on Android
- security research on Android native code

## When to choose
- you need lightweight inline hooking on Android ARM/Thumb without a full framework
- you want to inject instrumentation libraries into Android processes from the command line
- you are doing low-level Android security research on older devices

## When to avoid
- you need x86/ARM64 support or modern Android versions
- you want a maintained tool with active updates and support
- you prefer higher-level frameworks like Frida with scripting support

## Facets
- artifact type: library
