# Android Clean Architecture

This is a movies sample app in Kotlin, which is part of a serie of blog posts I have written about architecting android application using different approaches.

## What it is
A sample Android application demonstrating Uncle Bob's Clean Architecture approach, accompanied by a series of blog posts by Fernando Cejas. It includes both a Java version and a newer Kotlin version showcasing layered architecture, MVVM/MVP, dependency injection, and modularization.

## Use cases
- learn clean architecture on android
- example of layered android app architecture
- how to structure an android project with use cases and repositories
- mvp to mvvm migration example on android
- dagger 2 dependency injection example for android
- android app modularization example
- kotlin clean architecture sample

## When to choose
- you are learning or teaching clean architecture patterns for Android
- you want a reference implementation of layered Android architecture with use cases and repositories
- you want to see MVVM, RxJava, and Dagger 2 used together in a sample app

## When to avoid
- you need a production-ready framework or library to drop into your app
- you need actively maintained code with up-to-date Android APIs and dependencies
- you want Jetpack Compose or modern Android architecture components guidance

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, boilerplate
- domain: mobile-development, tutorials, developer-tools
- platform: jvm
- tags: clean-architecture, sample-app, android-architecture, kotlin, java, mvvm, mvp, dependency-injection, dagger-2, blog-series, android, mobile
