## What it is
A deprecated Android library that extends the compatibility library's ViewPager to support paging in both vertical and horizontal orientations, switchable at runtime. It is distributed as a standalone JAR and integrates with PagerAdapter implementations.

## Use cases
- add vertical page swiping to an Android app
- build a paged image gallery that scrolls up and down
- switch pager orientation between vertical and horizontal at runtime
- replace ViewPager with a direction-aware paging widget
- implement a vertical onboarding carousel on Android

## When to choose
- maintaining a legacy Android app already using this library
- targeting very old Android versions needing the compatibility library ViewPager with vertical paging

## When to avoid
- starting a new Android project - it is deprecated and unmaintained since 2011
- modern Android development where ViewPager2 supports vertical orientation natively
- projects needing ongoing bug fixes or recent Android support

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, mobile-framework
- domain: mobile-development, android-tools, frontend
- platform: jvm
- tags: viewpager, android-support-library, deprecated, paging, vertical-scrolling, horizontal-scrolling, android, mobile
