NASA Image of the Day App

This Android application utilizes the NASA APOD (Astronomy Picture of the Day) API to fetch and display space images. It uses a Clean Architecture approach, with Jetpack Compose for the UI, Retrofit for API calls, and Room for local database storage. The app supports an offline-first approach, allowing users to access data even when they are not connected to the Internet.

Features

• Fetch and display the Astronomy Picture of the Day from NASA API
• Uses Clean Architecture (core, data, domain, UI layers)
• Provides offline support through Room Database
• Jetpack Compose UI

Packages

• core

  • di: Dependency injection setup with Hilt.
  • network: Network-related classes like ApiResponse.
  • utils: Utility classes like Constants.

• data

  • remote: API call classes and DTO (Data Transfer Objects).
  • repository: Data source abstraction and repository classes.
  • local: Local data source with Room Database entities and DAOs.

• domain

  • model: Data classes that represent the business logic.
  • usecase: Business logic is separated into use cases.

• ui

  • view: Composable functions that define the UI.
  • viewmodel: ViewModel classes that interact with use cases and provide data to UI.

Dependencies

• Jetpack Compose for UI
• Retrofit for network requests
• Moshi for JSON parsing
• Hilt for Dependency Injection
• Room for offline database
• Kotlin Coroutines for asynchronous programming
• Coil for image loading
