Google's Android 17 exposes OS-level Gemini capabilities — Gemini Omni, Lyria 3 music generation, and AudioLM translation — to third-party developers as part of a broader 'Gemini Intelligence' agentic-OS push. For mobile builders this moves on-device generative and agentic primitives from app-bundled SDKs to platform APIs, lowering the integration cost for AI features. Confirm the exact API surface and availability tiers in Google's developer docs before planning around it.
