📖 Deep-Dive Documentation

Check out these detailed guides to understand exactly how Android DEX works under the hood:

1. Architectural Design : Three-layer system design, responsibilities, and data flow.
2. Boot & Initialization : Step-by-step connection flow with progress stages.
3. Reconnection System : Smart auto-healing, recovery phases, and UI overlay.
4. Real-Time Data Model : State store, JSON telemetry protocols, and message handling.
5. Error Handling : User-facing messaging pipelines and full fallback reference.
6. System Modules : Internal component roles, public APIs, and singletons.
7. Device Manager : ADB device selection, UI dialogs, and IP connections.

🛠️ How It Works — The Handshake Protocol

The system uses a three-layer architecture with a cryptographic-style handshake before the desktop UI unlocks. Every component must confirm readiness before the session begins.

📋 Getting Started

Prerequisites

• OS: Windows 10+, macOS 11+, or Modern Linux (Ubuntu, Fedora, etc.)
• Device: Android device running Android 8.0+
• Drivers: ADB is bundled — no separate installation needed

Step-by-Step

1. Enable Developer Options on your phone

   • Settings → About Phone → tap Build Number 7 times

2. Enable USB Debugging

   • Settings → Developer Options → USB Debugging → ON

3. Plug in your phone (for USB) or enable Wireless Debugging (for Wi-Fi)

4. Launch Android DEX — watch the boot progress bars fill to 100%

5. The desktop unlocks — your Android is now a full Windows desktop experience

If connection fails, a "Select Device" button appears in the boot screen — click it to open the ADB Manager and pick your device without restarting.
