## What it is
An Android-optimized port of the Joda-Time date/time library that fixes memory issues and allows shipping up-to-date timezone data independently of OS updates. It is now in maintenance mode, receiving only tzdb updates, as the author recommends java.time with desugaring instead.

## Use cases
- handle dates and times on Android without stale timezone data
- avoid Joda-Time's memory footprint problem on Android
- update timezone data in an Android app without an OS update
- use Joda-Time API in an Android project
- format dates with Android-style DateUtils utilities

## When to choose
- your project already uses Joda-Time and can't migrate to java.time
- you need current timezone data on devices with outdated OS tz databases

## When to avoid
- starting a new Android project - use java.time with desugaring instead
- you don't need updatable timezone data

## Facets
- artifact type: library
- maturity: maintenance
- function: date-time
- domain: mobile-development, developer-tools
- platform: jvm
- tags: joda-time, timezone-data, android-library, datetime, android
