A2A Course #3 - Build an A2A Agent with Google ADK + Gemini | Step-by-Step Demo + Code Walkthrough

In this video, we’ll build an end-to-end Agent-to-Agent (A2A) agent using Google’s Agent Development Kit (ADK) and Gemini models. If you’re excited about how AI agents communicate and want to understand the actual mechanics behind task exchange and message-based responses, this is the video for you.
