## What it is
A Python library that partially emulates Android native (.so) libraries on a host machine using the Unicorn CPU emulator. It emulates the JNI Invocation API, native memory, syscalls, and symbol-based hooking so native code can run and be analyzed outside a device.

## Use cases
- emulate an android native library without a device
- run jni_onload from an .so file in python
- reverse engineer android native code
- hook native functions by symbol table
- analyze arm native library behavior offline
- trace syscalls in an android .so

## When to choose
- you need to execute or analyze Android .so files from Python without an emulator or device
- you want to hook JNI functions and native symbols programmatically
- you are studying ELF loading and JNI internals

## When to avoid
- you need full Android app emulation or a complete runtime environment
- you require perfect fidelity for all syscalls or file system behavior
- you need a maintained production-grade emulation platform rather than an educational tool

## Facets
- artifact type: library
- maturity: active
- function: simulation, reverse-engineering, security, parser
- domain: reverse-engineering, security, android-tools, developer-tools
- platform: python, windows, cross-platform
- tags: android, jni, unicorn-engine, arm-emulation, elf, native-library, emulation, linux, macos
