Describe the Bug:
google/adk-recipes#1069
2026-02-12.11-54-25.mp4
When I speak to interrupt the model while it is generating a response, the system does not trigger the Interrupted event as expected. It triggers 'Turn Complete' event without 'Interrupted'. The interrupted in genai seems work well.
Why is the yield in the else?
Steps to Reproduce:
Please provide a numbered list of steps to reproduce the behavior:

Hello @Wu-Jiayang ,
Thank you for raising this issue. We were able to reproduce it and found that streaming continues even after the turn completion is logged, likely due to the model continuing to stream from the buffer. Your PR appears to fix this, it is currently under review and will be merged once all checks are complete.

I've noticed this issue too. when will it be resolved?

Apologies for the delay. The PR is still under review. Thank you for your patience.

Hello？

Why did bidi-demo suddenly stop supporting genai?
wuliang229 commentedon Apr 17, 2026
@Wu-Jiayang I'm reviewing your fix now. As for #4460 (comment), we don't maintain the examples codebase so please follow up in that repo.

@Wu-Jiayang you changed from yielding the LlmResponse to conditionally yielding. Did you actually see a duplicated interrupted Events?
Wu-Jiayang commentedon Apr 17, 2026
@wuliang229 I didn't actually check for duplicated events — I inferred the potential duplication from the code context. The main fix was that the original 'else' branch would cause interrupt signals to be lost.
