## What it is
TileView is an Android ViewGroup subclass that asynchronously renders, pans, and zooms very large images by composing bitmap tiles, with plugins for markers, hotspots, and path drawing. The project is no longer maintained and recommends the successor MapView library.

## Use cases
- display a huge map or floorplan image on Android with pan and zoom
- show deep-zoom tiled images in an Android app
- add markers and hotspots on top of a large tiled image
- render gigapixel images on mobile without out-of-memory errors
- draw paths over a tiled map view in Android

## When to choose
- you need to display extremely large images or maps in an Android app with smooth panning and zooming
- you want a tile-based image view with marker and hotspot plugins
- you're okay using an unmaintained library or its maintained successor MapView

## When to avoid
- you need active maintenance and support - the project is explicitly unmaintained
- you're building for platforms other than Android
- you prefer a modern Kotlin library - use MapView instead

## Facets
- artifact type: library
