This project demonstrates some topics when using Picasso, Glide, UIL and Fresco libraries.

They are:

• Disk and memory caching: how to enable/disable them for each library.
• Clearing entire cache: how to clear both disk and memory caches for each library.
• Callbacks: use of callbacks (sometimes referred as target) which gives us more control over the loading process.
• Cancel downloads on scrolling: avoid waste of network bandwidth by cancelling a download for a view when it is detached from the window.

It contains a nice drawer menu which allows us to easily change between the available download engines, enable/disable cache (disk and/or memory) as well as clear the entire cache with a simple click.

There is also a manual implementation. It was copied from this repository for the comparison purpose. We made just a few adjusts to fit it to the app architecture, but all the credits for this implementation go to the author of the library.
