Integration boundary
What connects to what
A Google ADK session emits a final response event; a separate speech adapter synthesizes only approved content and passes the audio into the avatar layer.
Prerequisites
- Current Google Agent Development Kit credentials and access
- Spatius App ID, Avatar ID, and an approved session-token flow
- A defined audio source, format, sample rate, and interruption policy
- A test environment that matches the target browser, device, or server runtime
Implementation path
Build a testable baseline
- 1
Confirm the current Google Agent Development Kit version and read both linked first-party sources.
- 2
Run the smallest official Spatius sample without the partner dependency to establish an avatar baseline.
- 3
Connect Google Agent Development Kit at the audio or session boundary described in the architecture section.
- 4
Verify audio format, pacing, interruption, reconnect, cleanup, and credential isolation.
- 5
Record versions, target devices, network conditions, failures, and rollback behavior before production.
Decision guidance
Best for and not best for
Best for
- Teams already committed to Google Agent Development Kit
- Developers who want to keep the avatar layer separable from the conversation stack
Not best for
- Teams requiring an unverified integration to be treated as production-ready
- Buyers looking for a fully managed end-to-end avatar-video service
Evidence-aware assessment
Advantages and limitations
Advantages
- Adds a Google Agent Development Kit-specific implementation decision instead of a generic provider list
- Keeps the Spatius rendering boundary explicit
- Provides a concrete validation and failure checklist
Limitations
- ADK is not Gemini Live audio. Verify event finality, streaming cancellation, and message identity, and keep this page noindex until a Spatius sample is runnable.
- No dedicated native connector is claimed by this page
- No first-party benchmark for this exact combined stack is included in the supplied evidence
ADK is not Gemini Live audio. Verify event finality, streaming cancellation, and message identity, and keep this page noindex until a Spatius sample is runnable. Indexing this guide does not convert an architecture blueprint into a claimed native connector; run and document the validation checklist before production use.
Page-specific FAQ
Implementation questions
Is Google Agent Development Kit a native Spatius connector?
No dedicated native connector is claimed. This page documents an architecture blueprint that must be validated in a runnable project.
What must be tested before production?
Credentials, audio access and format, sample rate, interruption, reconnect, backpressure, cleanup, privacy, versions, and target-device behavior.
Does this page include performance results?
No. It does not publish latency, FPS, bandwidth, or reliability numbers for this exact combined stack without a reproducible first-party test.
