Summary of Changes

Hello @tiwiz, 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 delivers a foundational Android Compose sample application. Its primary purpose is to illustrate the practical application of Window Size Classes, particularly the newly introduced Large and Extra Large breakpoints, to enable developers to build responsive user interfaces that adapt seamlessly across various screen sizes and device form factors.

Highlights

• New Sample Application: This pull request introduces a brand new Android Compose sample application designed to demonstrate the usage and behavior of Window Size Classes, specifically focusing on the new Large (L) and Extra Large (XL) breakpoints.
• Window Size Class Implementation: The sample showcases how to retrieve and interpret window size information using both the androidx.window library and the material3.adaptive APIs. It defines custom Width and Height enums to categorize window dimensions, including the new 'Large' and 'ExtraLarge' width classifications.
• Adaptive UI with Compose: The application's UI is built with Jetpack Compose and dynamically adapts its layout based on the detected window size class. It visually represents the current width and height classifications, providing a clear demonstration of adaptive design principles.
• Build Configuration: The PR includes a complete Gradle setup for a modern Android Compose project, utilizing Kotlin DSL for build scripts and managing dependencies via libs.versions.toml, including the necessary material3-adaptive, material3-window-size-class, and androidx.window libraries.

Code Review

This pull request sets up a new sample application to demonstrate Window Size Classes, particularly for Large and Extra Large screens. The project structure, Gradle configuration, and basic Android components are well-defined.

My review focuses on improving code safety and idiomatic Kotlin usage in the core logic files. I've identified a potential null pointer exception in Content.kt and suggested improvements for code consistency in WscUtils.kt. These changes will make the sample more robust and easier to understand.
