I'm not sure what "overlays" means. Does it mean things like the slideshows and videos?

Yes, that's the term used by Adobe, so we suggest using it now (instead of "enhancements" or "enrichments")

@libreliodev Is there an example to test this with?

Implemented but there may be out-of-memory issues #194

@intrications Indeed, there are out-of-memeory issues on an old Galaxy Tab. Can something be done?

I've tried switching to Picasso to load the images (which is a good idea anyway just for better code).

However, it doesn't seem to have improved the problem.

These are very large images we are displaying on top of the large images created to display the PDF. It is possible they are not being cleared out of memory correctly once they aren't on screen.

OK. I guess Crashlytics will tell us how critical the issue is.
