Summary of Changes

Hello @keyboardsurfer, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request integrates the Android AppFunctions API into the project by adding required dependencies and providing a concrete example of its usage. The new snippet showcases how to define and expose app functions for managing notes, allowing external systems to interact with the app's note-taking capabilities programmatically.

Highlights

• AppFunctions Dependencies: Added the necessary androidx-appfunctions dependencies and their versions to the gradle/libs.versions.toml file and included them in the misc/build.gradle.kts module.
• AppFunctions Snippet: Introduced a new Kotlin file, AppFunctionsApiSnippets.kt, which demonstrates the usage of the AppFunctions API for a note-taking application, including functions to list, create, and edit notes.
• Note Repository: Created a NoteRepository.kt file to provide a simple in-memory data store for the Note objects used within the AppFunctions snippet.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request adds a new snippet for AppFunctions, including the necessary dependencies, an AppFunctionsApiSnippets.kt file demonstrating the API, and a simple in-memory NoteRepository.kt. The implementation is a good start, but I've identified several areas for improvement, particularly in NoteRepository.kt. My feedback focuses on improving thread safety, encapsulation, and performance, as well as aligning the implementation of editNote with its documentation for better API design.
