Gemini Live API for Android

Build realtime Gemini sessions with audio capture, playback, interruption handling, session recovery and tool boundaries.

Intermediate to AdvancedSelf-paced7 modules13 available lessons

Your path, one skill at a time.

Build realtime Gemini sessions with audio capture, playback, interruption handling, session recovery and tool boundaries. Follow six teaching modules, each with a practical assignment, then combine the skills in the final project. Start with the introduction even if the tools are familiar: it defines the scope and boundaries of the path.

Self-paced. Complete each exercise and use its checkpoint before moving to the next module. Revisit any prerequisite you cannot yet demonstrate.

What you’ll learn

  • Measure first-audio latency and interruption stop time
  • Stop microphone and playback on session exit
  • Recover from a dropped connection without repeating a side effect

01MODULE 01What a Live API session is2 lessons · Self-paced
  • Bidirectional interaction
  • Model capability selection
  • Session ownership

Understand the difference between a persistent realtime session and a single generation request.

  1. 01What a Live API session isLesson · Self-paced
  2. 02Practice: What a Live API session isLab · Self-paced

Ready to move on when: Your design separates connection state from microphone and playback state.

02MODULE 02Microphone capture and audio formats2 lessons · Self-paced
  • Permission lifecycle
  • Encoding contract
  • Backpressure

Prepare input that the service can actually interpret.

  1. 01Microphone capture and audio formatsLesson · Self-paced
  2. 02Practice: Microphone capture and audio formatsLab · Self-paced

Ready to move on when: You can state the exact format of every audio buffer at the transport boundary.

03MODULE 03Playback and turn completion2 lessons · Self-paced
  • Chunk scheduling
  • Turn boundaries
  • Audio resource cleanup

Produce coherent output without racing the receive loop.

  1. 01Playback and turn completionLesson · Self-paced
  2. 02Practice: Playback and turn completionLab · Self-paced

Ready to move on when: Playback resources are released on stop, cancellation and connection failure.

04MODULE 04Interruptions and voice activity2 lessons · Self-paced
  • Voice activity decisions
  • Barge-in handling
  • Echo and timing

Make the assistant stop speaking when the user takes the floor.

  1. 01Interruptions and voice activityLesson · Self-paced
  2. 02Practice: Interruptions and voice activityLab · Self-paced

Ready to move on when: An interrupted response cannot resume due to a late network event.

05MODULE 05Live tools and session recovery2 lessons · Self-paced
  • Tool execution
  • Reconnect policy
  • Write uncertainty

Keep realtime convenience from creating duplicate or unauthorized actions.

  1. 01Live tools and session recoveryLesson · Self-paced
  2. 02Practice: Live tools and session recoveryLab · Self-paced

Ready to move on when: Recovery does not silently duplicate an externally visible action.

06MODULE 06Camera context and realtime evaluation2 lessons · Self-paced
  • Frame selection
  • Context freshness
  • Quality measurement

Add media only when it improves the actual task.

  1. 01Camera context and realtime evaluationLesson · Self-paced
  2. 02Practice: Camera context and realtime evaluationLab · Self-paced

Ready to move on when: You can demonstrate media consent, freshness and a measurable benefit from the camera input.

07MODULE 07Capstone and portfolio review1 lessons · Self-paced
  • Measure first-audio latency and interruption stop time
  • Stop microphone and playback on session exit
  • Recover from a dropped connection without repeating a side effect

Build a push-to-talk field assistant with visible session state, interruption support and one read-only lookup tool.

  1. 01Capstone: Gemini Live API for AndroidProject · Self-paced

Ready to move on when: Demonstrate every acceptance criterion and explain the tradeoffs without relying on the lesson text.

PROVE YOUR SKILLS

A portfolio you can build, explain, and defend.

  • Measure first-audio latency and interruption stop time
  • Stop microphone and playback on session exit
  • Recover from a dropped connection without repeating a side effect

Use the final review rubric to identify gaps. Lesson completion tracks study progress; readiness comes from independently demonstrating the work.
