Google announces unified on-device assistant API for Android and Wear OS

AI · 4 min read

Google's unified on-device assistant API provides a standardized way to run text, voice, and visual assistants across Android form factors. The runtime supports model selection, contextual memory controls, and fine-grained permission scopes so apps can request only the modalities they need.

The API is optimized for modern Android SoCs with hardware-backed ML accelerators and includes fallbacks to cloud processing when devices can't run heavier models. Importantly, Google built in user-facing controls that make persisted context visible and revokable, addressing privacy concerns seen in prior assistant features.

Developers will find sample integrations for search, UI generation, and conversational workflows. For UX teams, the update reduces fragmentation by providing a shared set of interaction patterns and accessibility behaviors across devices.
