(There are other ways of doing it, but let's stay clear of issues of DRM removal, etc - that's just complicating the matter.)
Most books I download are DRM-free. I can use Calibre to convert back and forth. I have other issues with wireless at this time, so I've been trying to use the usb cable route.
Regarding downloads from Amazon - the option to download to my Kindle is still active, but the 'Download to Android' is greyed out.
Sorry for being so clueless.
