Headunit Revived: The Ultimate Android Auto Emulator for your Tablet!

Breathe new life into your Android tablet or car headunit by transforming it into a fully functional, modern infotainment system. Headunit Revived allows you to experience Android Auto on almost any Android device—whether via USB, wirelessly, or using the innovative Self-Mode.

This project is an open-source revival of the original "Headunit" app by Mike Reid, modernized with the latest technologies and a sleek Material 3 interface.

NEW IN VERSION 2.0:
* Native Wi-Fi Direct (P2P) Support: Connect your phone wirelessly to your tablet without needing a manual hotspot. Connection establishment is fully automated in the background.
* Auto-Optimization Wizard: Tired of technical guesswork? Our new setup wizard scans your hardware and automatically recommends the best Resolution, DPI, and Codec for maximum stability.
* Advanced Screen Modes: Choose between "Immersive" (all bars hidden), "Hide Status Bar Only" (keeps navigation bar visible), or Standard mode. Ideal for devices where hardware buttons were previously obscured.
* Compatibility Fix for AA 16.4+: Full support for the latest Android Auto updates on your smartphone.

Key Features at a Glance:

🚀 Flexible Connectivity
* USB: Plug & Play. Supports stable connections via USB-OTG.
* Wireless (NSD): Automatically detects your phone on the same Wi-Fi network.
* Wi-Fi Direct: The most modern way to connect wirelessly—no shared network required.
* Self-Mode: Run Android Auto directly on your phone (local simulation), ideal for large displays or testing purposes.

🎥 High-Performance Video
* Supports H.264 and H.265 (HEVC) hardware decoding.
* Crystal-clear projection up to 1080p and 1440p (on supported hardware).
