Horizon Platform SDK - Android/Kotlin Integration Guide
When to Use
Use this skill when a developer:
- Wants to integrate any Horizon Platform SDK feature in a Meta Quest Android/Kotlin application
- Asks about setup, initialization, or dependencies for the SDK
- Needs help with a specific public platform API (achievements, IAP, users, etc.)
- Is troubleshooting errors or status codes from any SDK package
- Asks about HorizonServiceConnection, entitlements, or HzPlatformService

How to Use
- First, read
references/common-setup.mdfor shared setup instructions, initialization code, and common status codes that apply to all APIs. - Then, read the specific reference file for the API you need (e.g.,
references/iap.mdfor in-app purchases).
Each reference file contains only the package-specific content: API operations, data types, examples, and package-specific notes. The common setup and error codes are centralized in common-setup.md to avoid duplication.
