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.
