My Books App

Project Overview

This Android app fetches book data from the Stephen King API, focusing on specific fields like Title, Publisher, ISBN, and Year. The data is stored in a local Room database and displayed in a RecyclerView using the MVVM architectural pattern.

Technologies Used

• Android SDK
• JAVA | Kotlin
• Retrofit
• Room Database
• RecyclerView
• MVVM

Project Structure

The project follows a standard MVVM architecture with the following package structure:

• com.example.mybooksapp
  • Adapter: Contains the BookAdapter for displaying book data in the RecyclerView.
  • Dao: Includes the BookDao interface for database operations.
  • Database: Defines the BookDatabase class for managing the Room database.
  • Model: Contains the Book data class representing a book entity with the following fields:
    • id (Int)
    • Title (String)
    • Publisher (String)
    • ISBN (String)
    • Year (String)
  • Network: Handles network requests using Retrofit with the Api interface (likely named StephenKingApi or similar).
  • Repository: The BookRepository class mediates data access between the network and database.
  • ViewModel: The BookViewModel exposes data to the UI and handles business logic.
  • MainActivity: The main activity of the app.

API Integration

The app utilizes Retrofit to consume the Stephen King API, specifically targeting the fields mentioned in the Book data class. The fetched book data is parsed and mapped to Book objects for further processing.

Room Database

A Room database is employed to store book data locally. Data Access Objects (DAOs) provide methods for inserting, querying, and updating book information based on the defined fields in the Book class.
