## What it is
A set of Kotlin extension functions and properties that make Android app development more concise and idiomatic. The project was merged into AndroidX (core-ktx and related KTX libraries), and this repository is no longer used for development or issue tracking.

## Use cases
- write more concise Android code with Kotlin extensions
- simplify Android APIs like SharedPreferences, bundles, and resources
- reduce boilerplate in Android app development
- use idiomatic Kotlin wrappers for androidx APIs
- migrate Android KTX usage into AndroidX core-ktx

## When to choose
- you want idiomatic Kotlin extensions for Android APIs
- you are already using AndroidX and want the maintained core-ktx libraries

## When to avoid
- you are starting a new project - use the AndroidX KTX libraries instead
- you need bug fixes or new features, since this repo is abandoned and development moved to AOSP/AndroidX

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, developer-tools
- domain: mobile-development, android-tools, developer-tools
- platform: jvm
- tags: kotlin, kotlin-extensions, androidx, core-ktx, extension-functions, android
