## What it is
MarvelHeroes is a demo Android application showcasing modern Android development with MVVM architecture, Kotlin coroutines, Jetpack (ViewModel, Room, Lifecycle), Koin dependency injection, and Retrofit2. It serves as a reference sample for building Android apps with repository pattern, DataBinding, and Material Design components.

## Use cases
- learn MVVM architecture on Android with Kotlin
- example of Room database with repository pattern
- sample app using Koin dependency injection
- reference for Retrofit2 and coroutines in Android
- study Jetpack ViewModel and DataBinding usage
- see Material Design components in a real app

## When to choose
- you want a well-structured Kotlin Android sample demonstrating MVVM, Room, and Koin together
- you are learning modern Android architecture patterns from a working example

## When to avoid
- you need a production-ready app or actively maintained dependency versions (last release 2021)
- you need a reusable library rather than a demo application

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: mobile-framework, http-client, database, state-management, animation
- domain: android-tools, mobile-development, tutorials
- platform: jvm
- tags: mvvm, jetpack, room, coroutines, koin, retrofit, sample-app, databinding, material-design, dependency-injection, android
