## What it is
An Android library that automatically generates onSaveInstanceState and onRestoreInstanceState implementations via the @AutoRestore annotation. It works with Activities, Fragments, and Views through a Gradle plugin and annotation processing.

## Use cases
- eliminate boilerplate onSaveInstanceState code in Android apps
- automatically restore activity state after process death
- save and restore fragment fields with annotations
- persist view state across configuration changes
- generate instance state handling for Kotlin Android projects

## When to choose
- you maintain an Android app with lots of manual instance state saving code
- you want annotation-based automatic state persistence in Activities, Fragments, or Views
- you use Kotlin or Java with kapt and want code generation

## When to avoid
- you use Jetpack Compose or ViewModel/SavedStateHandle instead of classic instance state
- you need an actively maintained library - the project has had no releases since 2018
- your project does not use Android Gradle plugin integration

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, developer-tools
- domain: mobile-development, android-tools, developer-tools
- platform: jvm
- tags: android, annotation-processing, state-restoration, kotlin, gradle-plugin, boilerplate-elimination
