## What it is
Ion is an Android library for asynchronous networking and image loading, built on NIO and AndroidAsync. It provides a fluent API for downloading images, JSON, strings, and files, with automatic UI thread handling and request cancellation.

## Use cases
- load images into imageviews asynchronously in android
- download json from an api in an android app
- upload files with multipart form data and progress bar
- make http requests with kotlin coroutines on android
- cache and gzip http responses on android
- download files with progress callbacks

## When to choose
- building an Android app that needs simple async HTTP and image loading in one library
- you want automatic cancellation tied to Activity lifecycle and UI thread callbacks
- you need animated GIF support in ImageViews

## When to avoid
- building a multiplatform or non-Android Java/Kotlin project
- you prefer modern first-party stacks like Retrofit/OkHttp or Coil with active ecosystems
- you need a lightweight image loader only without networking

## Facets
- artifact type: library
- maturity: maintenance
- function: http-client, image-processing, caching, file-upload
- domain: mobile-development, android-tools, web-development
- platform: jvm
- tags: android, async-networking, image-loading, kotlin-coroutines, http2, mobile
