Source: Google Developers Blog

Overview

Google has released version 1.0.0 of the Agent Development Kit (ADK) for Java. This update introduces a suite of new capabilities aimed at simplifying the creation and management of AI agents in Java environments.

New Features

• Google Maps Grounding – Agents can now incorporate geographic context directly from Google Maps.
• Built‑in URL Fetching – Simplifies data retrieval from web resources without external libraries.
• Agent2Agent Protocol – A standardized protocol that enables cross‑framework collaboration between agents.

Architecture Enhancements

App & Plugin Model

• Provides a modular structure for extending agent functionality.
• Supports global logging across all components.

Automated Context Window Management

• Uses event compaction to keep the context window efficient and relevant.

Human‑in‑the‑Loop Workflows

• Allows optional human confirmation before agents execute actions, improving safety and control.

Session and Memory Services

Google Cloud Integration

• Firestore for persistent storage of session data.
• Vertex AI for handling large data artifacts and long‑term state management.

These services give developers robust tools for maintaining agent memory and managing complex interactions over extended periods.
