## What it is
An Android library by Facebook that listens to the app's existing network traffic and classifies the user's connection quality into discrete buckets. Developers can subscribe to quality-change events and adapt app behavior like requesting lower-quality media.

## Use cases
- measure downstream bandwidth on android
- detect when user's network quality changes
- serve lower quality images on slow connections
- adapt video streaming quality to connection
- monitor network performance in an android app

## When to choose
- you need passive bandwidth estimation from real app traffic on Android
- you want to dynamically adjust media quality based on connection class

## When to avoid
- you need latency or upstream bandwidth measurement
- you need an actively maintained library - it is archived by Facebook
- you are not building an Android/JVM app

## Facets
- artifact type: library
- maturity: maintenance
- function: monitoring, networking
- domain: mobile-development, networking, android-tools
- platform: jvm
- tags: network-quality, bandwidth-measurement, android-library, facebook-archive, connection-classification, android, mobile
