CryptoCoinTracker

CryptoCoinTracker is an Android application written in Kotlin, utilizing Kotlin DSL for a clean and readable build configuration. The app demonstrates the use of various modern Android development technologies and libraries to create a robust and efficient cryptocurrency tracking application.

Features

• MVVM Architecture: The app follows the Model-View-ViewModel (MVVM) architecture pattern, promoting a clean separation of concerns and making the codebase more maintainable.
• Clean Architecture: Adheres to Clean Architecture principles to ensure a scalable and testable code structure.
• Retrofit2: Used for making API requests to fetch cryptocurrency values from a public API.
• GSON: Employed to parse JSON responses from the API into Kotlin data classes.
• Room: Serves as the local database to store cryptocurrency values for offline access.
• LiveData: Ensures the UI components observe changes in the data and update automatically.
• Picasso: Handles image loading and caching within the app.
• Coroutines: Used for asynchronous programming, making the app responsive and efficient.
• Foreground Service: Keeps the app running in the background to continuously fetch and update cryptocurrency values even when the app is closed, using CoroutineWorker for background processing.

How It Works

1. Data Extraction: CryptoCoinTracker fetches real-time cryptocurrency values from a public API using Retrofit2.
2. Data Storage: The fetched data is parsed with GSON and inserted into a Room database.
3. Data Display: The app's UI observes the data stored in the Room database via LiveData and displays the cryptocurrency values using a clean and intuitive interface.
4. Background Updates: A Foreground Service ensures that data fetching and updating continues even when the app is closed, leveraging CoroutineWorker for efficient background operations.
