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
