Events in Google ADK | Debug Tool Calls, Timeline & State Changes (Dev UI Walkthrough)

In this video, we do a practical deep dive into Events in Google ADK — the runtime’s timeline of everything that happens during an agent run. We run 3 of our previous agents inside adk web and inspect the event payloads / JSON to understand tool calls, tool results, state updates, and control signals. 📘 What we covered • What Events are in Google ADK and why they matter for debugging • How to read the runtime timeline in adk web using event payloads / JSON • How to identify event “types” quickly • How tool calls, tool responses, and state changes show up as events 👇 Chapters 00:00 - Intro 00:26 - What Events represent in ADK 02:43 - Event structure 03:58 - Demo 12:07 - Wrap-up 📂 Resources • Reference code: ADK Events → https://github.com/ai-suyash/genai-youtube/tree/main/tutorials/google-adk/09_adk_events 🎥 Previous videos → Video 1: Build Your First AI Agent with Google ADK → https://youtu.be/NU05aTvRiJM → Video 2: Function Tools in Google ADK (Finance Assistant) → https://youtu.be/NnQsX5FiOak → Video 3: OpenAPI Tools in Google ADK (Chuck Norris API) → https://youtu.be/q3jm48R0Brw → Video 4: Sequential Agents in Google ADK (Podcast Transcript Assistant) → https://youtu.be/WfZSHQrD14Y → Video 5: Parallel Agents in Google ADK (Multi-Agent Travel Planner) → https://youtu.be/czNGyHkKdew → Video 6: Loop Agents in Google ADK → https://youtu.be/QGcVTjeQYXA → Video 7: Callbacks in Google ADK → https://youtu.be/NANNKCiLz0I → Video 8: How Google ADK Agents Run → https://youtu.be/dSQqCWK18dQ 📺 Playlists → Building AI Agent with Google ADK Playlist → https://www.youtube.com/playlist?list=PL2OwQjtoKA1F4m0__4e8gh_X0YZqRpm9Z → Function calling Playlist → https://www.youtube.com/playlist?list=PL2OwQjtoKA1G5lcXPNodN390dn7gZWonm #adk #googleadk #llm #genai #aiagents #events #debugging #observability #developers
