## What it is
A demo Android application showcasing Trinea's Android common libraries, including image caching, HTTP caching, pull-to-refresh ListView, auto-scrolling ViewPager, and DownloadManager usage. It serves as runnable sample code accompanying the trinea-android-common library and related blog tutorials.

## Use cases
- learn how to implement image caching in android
- example of pull to refresh listview with load more
- android downloadmanager usage example
- auto scrolling viewpager carousel demo
- sample code for android http cache
- learn viewpager and fragment patterns in android

## When to choose
- you want runnable examples of Trinea's android-common caching and UI components
- you are learning classic Android patterns like pull-to-refresh, ViewPager, and DownloadManager

## When to avoid
- you need a production-ready library to depend on - this is a demo app, not a library
- you want modern Android development with Kotlin, Jetpack Compose, or current architecture patterns
- you need actively maintained code - the project is old and has no license
