How It Works

1. ViewModel: Manages UI-related data and communicates with the repository.
2. Repository: Handles data operations, fetching either from the local database (if data is less than 30 minutes old or there's an error in the remote) or the remote Open Exchange Rates API.
3. Local Database (Room): Persists exchange rates data locally.
4. Remote API (Open Exchange Rates): Provides the latest exchange rates.

Technologies Used

• Kotlin: Programming language for Android development.
• ViewModel and LiveData: Architecture components for managing UI-related data.
• Hilt: Dependency injection library for Android.
• Room: Persistence library for local database.
• Clean Architecture: Organized project structure for better maintainability.
• Retrofit: HTTP client for making API calls.
• Coroutines: Asynchronous programming for efficient and responsive app behavior.
• Unit Testing: jUnit and mockk for testing components.

1. Execute the following command in the terminal: ./gradlew test
2. Right-click on the test folder in Android Studio, then select "Run Tests."
