Adobe DE is available on MACos, Windows, and iOS, and now also Android. Some time last summer Adobe quietly launched a new version of its epub-reading app, Adobe Digital Editions.
One eBook reader for all your Adobe DRM protected books across your Android Devices, iPad, Mac or PC. Adobe Digital Editions (ADE) is free-to-download and use, and completely ad-free. Use it to read EPUB and PDF books, both online and offline. Borrow ebooks from many public libraries for use with ADE. Extend your reading experience by transferring books from your personal computer to your Android devices. Organize your books into a beautiful custom library.
I would suggest you take the description with a grain of salt, mix vigorously, and then pitch both over your shoulder. This app as a 2.5-star rating with almost as many 1-star reviews that 2-, 3-, 4-, and 5-star reviews combined.
Don't download this app; instead you should install Aldiko, Bluefire, Pocketbook, or another Epub Android app which supports Adobe DE.
There are many options, so there is no need to cause yourself pain by trying to use Adobe DE.
