Google Agent Development Kit - Complete Tutorial for Building AI Agents

Learn to build powerful AI agents using Google's Agent Development Kit (ADK) in this comprehensive 15-minute tutorial that demonstrates the simplest approach to creating, evaluating, and deploying AI agents with built-in UI and API server capabilities. Master six different agent types including basic question-answering agents, tool-integrated agents with real-time Yahoo Finance stock data fetching, state-enabled agents with memory capabilities, multi-tool agents combining stock prices and company information, structured output agents using Pydantic for consistent responses, and callback agents with debugging and tracing functionality. Discover how to implement multi-agent systems without complexity while utilizing visual debugging tools, built-in state management, session handling, conversation memory, real-time data integration with custom tools, and one-command deployment to Google Cloud. Follow along as you build practical agents including stock price checkers with live market data, memory-enabled agents that retain search history, multi-functional agents with comprehensive market analysis tools, structured response agents providing buy/sell recommendations, and debug-friendly agents with callback monitoring. Set up your development environment with Python, Google API keys from AI Studio, Y-Finance library for stock data, and Pydantic for structured outputs while learning essential installation commands and deployment procedures. Explore why Google ADK surpasses other frameworks like AutoGen, LangGraph, and Crew AI through its simplified approach that enables building functional agents in minutes with just a few lines of code, multiple model support with full transparency, visual debugging capabilities, and flexible deployment options including Vertex AI Agent Engine, Google Cloud Run, and custom infrastructure. Access complete source code for all six agent types, understand real-time stock data fetching and analysis, implement conversation memory and state management, utilize tool interaction visualization in web UI, manage sessions with unique identifiers, create structured responses with consistent formatting, implement callback functions for debugging and monitoring, and generate automatic API documentation for seamless integration and deployment.
