Key Architectural Components #

1. Host System Layer: The Android OS running on your physical device

   • Provides hardware access and resource management
   • Runs the Twoyi application as a standard app
   • Remains completely unmodified and secure

2. Container Application Layer: The Twoyi app itself

   • Manages the virtualized environment
   • Handles resource allocation and isolation
   • Provides the user interface for managing the container

3. Virtualized Android Layer: The Android 8.1 environment

   • Complete Android system with its own processes
   • Isolated file system and resource management
   • Custom HAL implementation for hardware virtualization

4. Container Applications Layer: Apps running inside Twoyi

   • Applications can be imported from the host or installed directly
   • Each app runs in the container's Android environment
   • Apps have access to container-specific features like root
