Google Releases Kotlin Agent Development Kit for Building On-Device AI

Google has released the Agent Development Kit (ADK) for Kotlin 1.0, a production-ready framework that allows developers to build AI agents across various platforms using Kotlin.

The ADK brings Kotlin to feature parity with Google's ADK for Python and Java, while adding Android-specific capabilities for on-device and hybrid AI.

The ADK supports hierarchical multi-agent systems, context compaction and multi-turn conversation, session management, and first-class Java interoperability.

Developers can now use idiomatic Kotlin APIs for orchestration, tool support, persistence, memory, and human-in-the-loop workflows without relying on Python.
