## What it is
An Android library providing a city selection dialog with alphabetical index bar, hot cities, pinyin/name search, and a pluggable location interface, similar to pickers in Meituan or Ele.me apps. It is built on DialogFragment and integrated via JitPack with one-line setup.

## Use cases
- add a city picker to an android app
- let users search cities by name or pinyin
- show hot cities with alphabetical navigation
- integrate city selection with custom location SDK
- build a meituan-style city selection screen

## When to choose
- you need a ready-made Chinese city selection UI on Android
- you want hot cities, search, and letter index out of the box
- you want to plug in your own location provider

## When to avoid
- you need non-Chinese city data or international city lists
- you need a Jetpack Compose implementation
- you require an actively maintained library with a license

## Facets
