Image Cache

An image download-and-cacher that also knows how to efficiently generate and retrieve thumbnails of various sizes.


  • easily integrates into content-provider backed applications, providing an adapter that can read local and web URLs from a cursor
  • automatic generation and caching of multiple sizes of images based on one downloaded asset
  • provides a disk cache as well as a memory cache
  • automatic disk cache management; no setup necessary, but parameters can be fine-tuned if desired
  • designed to work with your existing setup: no extending a custom application or activity needed
  • cursor adapter supports multiple image fields for each ImageView; skips fields that are null or empty
  • cursor adapter has an automatic progress bar when loading the cursor


Please see the test/ directory for both a simple example of using it as well as some unit tests. When running the application in test/ make sure to run it as an Android activity if you want to see the demo.

Both the unit tests and the interactive test load some images from our lab's servers.
