## What it is
An Android library that generates combined group-chat avatar bitmaps in the style of DingTalk and WeChat. It accepts image resource IDs, bitmaps, or URLs, handles loading with thread pools and disk/memory caching, and supports sub-image click events.

## Use cases
- generate WeChat-style group avatars in an Android chat app
- create DingTalk-like combined group profile images
- compose multiple bitmaps into one grid avatar
- load network images into a combined avatar with caching
- handle clicks on individual sub-images in a group avatar

## When to choose
- you need WeChat or DingTalk style group avatars on Android
- you want a ready-made layout manager for combined avatar bitmaps
- you need caching and sampling compression when composing images from URLs

## When to avoid
- you are not building an Android app
- you need fully custom avatar layouts beyond the WeChat/DingTalk styles
- the project needs active maintenance, as the latest release was in 2022

## Facets
- artifact type: library
- maturity: maintenance
- function: image-processing, ui-components
- domain: mobile-development, android-tools
- platform: jvm
- tags: group-avatar, bitmap-composition, chat-ui, image-caching, jitpack, android
