Custom Minecraft Java Launcher for Android

A high-performance, modular Minecraft: Java Edition launcher built natively for Android. This project implements a custom JVM bridge, Microsoft OAuth authentication, and a virtual input overlay.

🚀 Features

• Auth: Full Microsoft/Xbox Live OAuth 2.0 integration.
• Rendering: Native EGL bridge for OpenGL SurfaceView.
• Performance: Multi-threaded asset downloader and G1GC optimizations for ARM.

🏗️ Architecture

The launcher is divided into several core modules:
