Description
Description:
Interactions API ( https://blog.google/innovation-and-ai/technology/developers-tools/interactions-api/) provides a unified interface for interacting with Gemini models and agents with stateful multi-turn conversations and server-side history management.
This feature is already available in adk-python (since v1.21.0) but is currently missing in adk-java, creating a feature parity gap between the two SDKs.
Proposed Solution
Add support for the Interactions API in adk-java, similar to how it's implemented in adk-python with the use_interactions_api=True parameter in the Agent configuration.
