## What it is
An Android library that generates nine-patch window background drawables to make app cold starts look faster and visually consistent. It provides Material Design templates that draw an appbar and status bar background during the launch window before Activity.onCreate().

## Use cases
- make my android app launch look faster
- remove white flash on app cold start
- show appbar background during cold start
- create a branded launch theme for android
- generate nine-patch window background drawables
- improve perceived startup performance of android app

## When to choose
- you have a Material Design Android app with an AppBar and want visual consistency during launch
- you want to eliminate the blank/white glitch during cold start
- you want a framework-level launch preview without a splash logo

## When to avoid
- your app is not Android or does not use Material Design appbars
- you want a splash screen with a logo or animation instead
- you need actively maintained tooling, as the project has not released since 2019
