Technologies Used

1. Kotlin

• Description: Modern programming language for Android development.
• Benefits: Concise syntax, null safety, and strong functional programming support.

2. Jetpack Compose

• Description: UI toolkit for building native Android UIs.
• Benefits: Simplifies UI development with a declarative approach and reduces XML usage.

3. Retrofit

• Description: Type-safe HTTP client for Android.
• Benefits: Simplifies API calls and JSON parsing, supports asynchronous requests.

4. Hilt

• Description: Dependency injection library for Android.
• Benefits: Simplifies dependency management and improves testability.

5. Coroutines

• Description: Asynchronous programming framework in Kotlin.
• Benefits: Simplifies async code, reduces callback hell, and provides structured concurrency.

6. Room

• Description: Persistence library for SQLite.
• Benefits: Simplifies database interactions, supports compile-time SQL verification.

7. Material Design

• Description: Design system for building visually appealing UIs.
• Benefits: Ensures consistency and usability across the app.

8. LiveData and StateFlow

• Description: Observable data holders for UI components.
• Benefits: Lifecycle-aware updates and better state management.

Architecture Overview

The app follows a clean architecture pattern, which promotes separation of concerns and enhances maintainability.

Network Handling

• Retrofit is used to make API requests to cryptocurrency APIs (e.g., CoinGecko, CoinPaprika).
• Proper error handling is implemented to manage network issues and inform users.

Data Mapping

• Data Transfer Objects (DTOs) represent the structure of JSON responses.
• Mapping functions convert DTOs to domain models for use in the application.

Domain Logic

• Use Cases encapsulate business operations and interact with repositories.
• Repositories mediate between data sources and the domain layer, providing a clean API for data access.

Observing Data

• LiveData and StateFlow are used in ViewModels to expose data to the UI.
• The UI reacts to changes in data, ensuring a responsive user experience.

Data Sources

• Remote Data Source: Fetches data from APIs using Retrofit.
• Local Data Source: Interacts with the Room database for offline data storage and retrieval.
