android jetpack compose
via PatrickJS/awesome-cursorrules
Android development with Jetpack Compose, clean architecture, and Material Design 3.
What is android jetpack compose?
This rule guides Android development using Jetpack Compose with emphasis on clean architecture, proper state management, and performance optimization. Use it when building modern Android UIs with Compose, ViewModel, Hilt dependency injection, and unidirectional data flow patterns.
- Adapt to existing project architecture while applying Jetpack Compose best practices and clean architecture principles
- Implement Material Design 3 components and theming with proper state hoisting and recomposition optimization
- Use Kotlin coroutines, Flow, and ViewModel for asynchronous operations and unidirectional data flow
- Set up dependency injection with Hilt and organize code into domain, data, and presentation layers
- Optimize performance through lazy loading, proper key usage, and efficient state management
- Write unit tests for ViewModels and UseCases, and UI tests using Compose testing framework

// Android Jetpack Compose .cursorrules
// Flexibility Notice
// Note: This is a recommended project structure, but be flexible and adapt to existing project structures. // Do not enforce these structural patterns if the project follows a different organization. // Focus on maintaining consistency with the existing project architecture while applying Jetpack Compose best practices.
