This is an Android application designed as a learning resource for Kotlin Coroutines. It provides a series of hands-on examples demonstrating common coroutine patterns in Android development, including single/parallel/series network calls with Retrofit, Room database operations, long-running tasks, timeout handling, and error handling strategies (try-catch, CoroutineExceptionHandler, supervisorScope). The architecture follows a simple MVVM pattern with ViewModel, LiveData, and a sealed UiState class. The code is straightforward and intended for educational purposes, with a clear separation of layers (API, database, UI). While it does not exhibit advanced or production-grade architecture, it serves as a practical reference for developers learning coroutines.
The LLM identified 2 files worth highlighting for reuse:
A sealed interface representing UI state with Success, Error, and Loading variants. This is a clean, reusable pattern for managing asynchronous UI state across Android apps. It is decoupled from any specific business logic and can be easily extracted and used in any Kotlin project with LiveData or StateFlow.
A JUnit TestRule that sets up a TestCoroutineDispatcher and scope for unit testing coroutines. It provides a `runBlockingTest` method to execute suspending tests in a controlled environment. This is a reusable utility for any coroutine-based Android project, eliminating boilerplate in test files.
