Did you know that since Titanium 3.1 remote images are cached automatically on Android, just like they have always been on iOS?
Well, I don’t blame you for not knowing, since the Appcelerator Docs on this very day still preach the best practice of manually caching remote images. I didn’t know either when I made the fairly popular CachedImageView widget to bring this technique to Alloy.
When I found out in August I created a ticket requesting the docs to be updated right away. Yesterday, this ticket has been resolved so we can expect the docs to be updated some time soon.
