Google has released version 1.0 of its Agent Development Kit (ADK) for Kotlin, expanding its toolkit for building AI agents tightly integrated with Google Cloud services.

The ADK offers features and an interface similar to the Python version, which is also available, as well as Java and Go versions. It allows developers to define agent behavior, orchestration, and tool use directly in code, providing fine-grained control and flexibility for debugging, versioning, and deployment on both local devices and in the cloud.

ADK Kotlin agents can run on Android either fully on-device or against the cloud, with three backends currently available: LiteRT-LM, Gemini Nano, and Firebase. These models use different AI frameworks and have varying capabilities for tool calling and orchestration.
