## What it is
Twoyi is a lightweight Android-in-Android container that runs a nearly complete Android 8.1 system as a normal app on Android 8.1-12 devices without root. It enables root inside the container, Xposed frameworks, and customizable system components like virtual HAL layers.

## Use cases
- run a rooted Android environment on a non-rooted device
- use Xposed or LSPosed without unlocking the bootloader
- test apps in an isolated Android container
- implement virtual camera or virtual sensors via HAL virtualization
- do Android security research such as shelling

## When to choose
- you need root or Xposed on a device you cannot unlock or root
- you want a fast-booting, isolated Android sandbox for testing or research

## When to avoid
- you need ongoing support or updates - the project is officially discontinued
- you need a recent Android version inside the container (internal system is Android 8.1)
- you want to build the internal ROM from source - it is not fully open-sourced

## Facets
- artifact type: application
- maturity: abandoned
- function: container-runtime, security
- domain: android-tools, operating-systems, security
- platform: -
- tags: android-container, rootless, virtualization, xposed, discontinued, android
