Building a Simple Android MVVM App with Jetpack Compose

In this tutorial, you’ll learn how to create a simple Android app that displays a list of images. We’ll use Jetpack Compose, Kotlin, Coil, Retrofit, and Material3 to build the app. This tutorial focuses on implementing the MVVM (Model-View-ViewModel) architecture for a clean, scalable design.

Understanding MVVM Architecture
MVVM separates concerns into three components: Model, View, and ViewModel.

1. Model
      Represents the data layer of the application.
      Handles business logic and data operations (e.g., API or database interactions).
      Independent of both View and ViewModel.
        Examples: Room database, Repository classes.
2. View
      Represents the UI layer.
      Observes the ViewModel to display data and handles user input.
        Examples: Activities, Fragments, or Composables.
