Download the Adobe Content Viewer (https://play.google.com/store/apps/details?id=air.com.adobe.contentviewer&hl=en) to your Android device.
Sign in and download folios. You won't be able to download folios with PDFs, and some other stuff doesn't work, but it's pretty easy. You can make rendtions, folios etc to match the device's resollution/screen size.
Thanks Angusdog, we've just started looking at a renditions workflow, it feels good to have new screen sizes to work and experiment with too.
