I'm specifically looking at doing this in a CardScrollAdapter, but it would be also good to know in the LiveCard situation when publishing a card to the timeline. Is there a way to use volley or any other networking library to load images using the generic Card class?
"There's the additional complexity that the current XE12 GDK only supports card.addImage(Uri) with local resource and file URIs. So in addition to the caveat above, you have to download the image to a file before being able to add it as a card image."
Looks like XE16+ now supports card.addImage(bitmap) so using a file as an temporary cache may no longer be necessary.
