README 中文版

Twoyi is a lightweight Android container. It runs a nearly complete Android system as a normal app (no root required) on Android. Additionally, it supports Android 8.1 ~ 12.

1. Using Taichi·Yang without unlocking the bootloader. Xposed, EdXposed and LSPosed will be supported later.
2. Using root on non-rooted devices.
3. Magisk modules will be partially supported.
4. Implementing additional system components such as virtual camera by virtualizing the HAL layer.
5. Doing security research such as shelling.

1. Twoyi is a rootless Android system-level container, which runs a nearly complete Android system as a normal app and is mostly isolated from the main system.
2. The internal Android version is Android 8.1 and Android 10 will be supported later.
3. Starting up Twoyi is very fast and the system can be booted in about three seconds except for the initialization.
4. Twoyi is an open source project.
5. The internal system of twoyi will be fully customizable. Because its system is open source, you can fork the project to compile your own AOSP. You can also customize the system components, such as the HAL layer to implement virtual cameras, virtual sensors and other special features.

Twoyi can be divided into two parts:

1. The twoyi app, which is actually a UI rendering engine.
2. The internal ROM of twoyi.

This repository contains the twoyi app, and the twoyi ROM is being turned into open-source. Therefore, at this time, the ROM cannot be compiled from the source code yet.

WIP

Twoyi is partially written in Rust, so it's nessesary to install Rust and Cargo first.

Please refer to cargo-xdk.

You can check if it is installed by running ./gradlew cargoBuild. If it succeeded, you will see libtwoyi.so in app/src/main/jniLibs/arm64-v8a.

PS. Please use the ndk 22 or lower version, otherwise it may build fail.

The ROM of twoyi is being turned into open-source, so you cannot build it now. You can use the prebuilt ROM instead. To do that, extract rootfs.7z from the official release apk and copy it to app/src/main/assets.

Build it with Android Studio normally.
