## What it is
A lightweight, highly customizable Android library for in-app version updates, handling update dialogs, APK background downloading, notification progress, and installation. It supports both Java and Kotlin, works without storage permissions, and can also be used as a standalone APK downloader.

## Use cases
- check for app updates and prompt users to upgrade on Android
- download and install an APK in the background with a progress notification
- implement forced app updates with a download progress dialog
- build a custom in-app update dialog for Android
- use an Android library as a simple APK downloader without storage permissions

## When to choose
- you need a simple, lightweight Android in-app update solution with minimal dependencies
- you want customizable update dialogs, forced updates, and notification progress out of the box
- you need support for old Android versions (4.1+) and Android 13 notification permission handling

## When to avoid
- you distribute your app through Google Play, where in-app APK updates are restricted
- you need a cross-platform update solution for Flutter or other non-native frameworks
- you require enterprise-grade update orchestration with staged rollouts and server-side management
