Note

This repository contains the official VHAL Properties (DEFAULT / SYSTEM) of Android 14 and Android 15 defined by Google. Be aware that OEMs may also develop new VENDOR Properties, which may or may not be available for 3rd Party Apps.

VHAL Skills for Android Automotive OS

Structure

• aaos-vhal-skills: Holds the standard AOSP properties.
  • android14-release: Android 14 rules and properties.
  • android15-automotiveos-release: Android 15 rules and properties.
• oem-vhal-skills-template: A starter kit for auto makers (OEMs) to document their own custom properties.

How to use

1. Pick the folder for the Android version you're building against.
2. Point your IDE tool (Copilot, Cursor, whatever) to the SKILL.md file in that folder.
3. Keep SKILL.md and properties-reference.md together. The AI reads the reference file when it needs to look up a specific property, so they have to stay bundled.

Future Versions

If Google ever decides to bless us with a new Android OS version and a completely revamped VHAL, I'll eventually get around to releasing a new skill for it.

Acknowledgment

A massive thank you to @google for loving open source. Without your documentation, this repository wouldn't exist. Keep being awesome!

Sincerely, feevlic
