## Capabilities
Mobile Harness unites modern **Jetpack Compose UI** with a self-contained **Ubuntu 20.04 LTS subsystem**. It gives you a desktop-class software development environment in your pocket without requiring root access, unlocked bootloaders, or external applications like Termux.
 Autonomous Agent Coding 
 Native integrations with Claude Code, DeepSeek Harness, and Antigravity CLI. Each agent has an isolated driver, settings, and resumable project conversations. 
 Isolated Linux Subsystem 
 A full Ubuntu 20.04 ARM64 userspace running inside PRoot. Includes Node.js, npm, Git, OpenSSL, and essential shell tooling out of the box. 
 Instant Web Preview 
 Spun up a Vite, Next.js, or Express server? Test web interfaces in real-time within a restricted, sandboxed mobile WebView with console telemetry. 
 Keystore-Grade Encryption 
 Your API keys and credentials are encrypted using Android Keystore-backed AES-256 GCM. No telemetry, no remote proxies, and zero plain-text leaks. 
 Persistent Project Sessions 
 Keep projects, chat history, files, and task context together so work can continue across app sessions. 
 Native File Workflow 
 Browse, edit, search, and attach files directly from the app interface. Interoperate with system storage via Android Storage Access Framework (SAF). 
 On-device Android Builds 
 Build, install, and launch Android APKs directly on the phone without USB or wireless ADB pairing. 
 Optional Toolchains 
 Add Python, Android, C/C++, and PHP tooling only when a project needs it.
