## What it is
A well-known Android sample project demonstrating Jetpack MVVM best practices, designed as a companion to the author's article series on Jetpack architecture components. It showcases standardized development patterns using ViewModel, LiveData, DataBinding, and Navigation through carefully crafted app scenarios.

## Use cases
- learn jetpack mvvm architecture for android
- understand viewmodel and livedata responsibilities
- see best practices for android app architecture
- handle configuration changes like rotation without state loss
- structure an android project with mvvm pattern
- learn data binding and navigation component usage

## When to choose
- you are an Android developer learning Jetpack MVVM from a real, complete example
- you want a reference architecture for structuring ViewModel/LiveData/DataBinding usage
- you want to understand why each Jetpack component exists and its boundaries

## When to avoid
- you need a production-ready library or framework to drop into your app - this is a sample/educational project
- you use Kotlin-first modern Android stacks like Compose, since this project is Java-based
- you need a maintained dependency with a license - the repo has no license and is in maintenance mode

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: mobile-framework, state-management, ui-components, developer-tools
- domain: android-tools, mobile-development, tutorials, web-development
- platform: jvm
- tags: jetpack, mvvm, android-architecture, viewmodel, livedata, databinding, sample-project, best-practices, android
