In February 2026, Lina Zhao developed comprehensive developer documentation for the google-ai-edge/gallery repository, focusing on enabling custom logic and function calling within the Android application. She authored the Function_Calling_Guide.md, which details the workflow for cloning the repository, defining action types, adding tool definitions, and implementing action logic using Kotlin and Markdown. This documentation established a clear, reusable template for integrating custom logic, supporting consistent and scalable function-calling capabilities across the project. Lina’s work addressed onboarding challenges and laid a technical foundation that accelerates future feature development, demonstrating depth in Android development and mobile engineering practices within a collaborative environment.
