Android smartphones are not supported by ADE, which means that the protocol
for hooking up ADE to your smartphone in order to transfer ebooks won't
work. Aldiko is an app that reads ebook file types, no matter how they
were transferred to your smartphone. Let's work from there.
Adobe Digital Editions has limits of supported devices. As stated in its
HELP section, you can have up to two computers and four ereaders supported
by a copy of ADE. ADE keeps track of each device when it's 'new' and
increments a counter on the central computer at Adobe. Each time you try
to activate your smartphone, even though it's not supported, your
activation counter is increased until it hits the limit. You have to
contact Adobe and get the technical support guys to reset your counter.
Some of them are quite helpful - others try to brush you off. Be
DRM isn't something you can get rid of. Digital rights were established by
the Digital Millenium Copyright Act of 2000, and are implemented in
epublication software. These rights are assigned, managed and controlled
by publishers, distributors and even authors of epublications, and can't be
changed by the user. What happens often is that the DRM is set to prohibit
copying an epublication once it's downloaded. That setting prevents you
from transferring the epublication to your ereader once you've downloaded
it to your computer. Nothing you can do about it - sorry. As a point of
information, Adobe created one set of the software that manages digital
rights - Content Server. Don't get that confused with Digital Editions,
which is a library management system. BTW: Aldiko also observes DRM.
My suggestion is that you investigate how you're supposed to download
epublications directly to your smartphone if you haven't already (that
point's not clear from your post). Aldiko will manage the epublication and
you won't have to worry about a transfer from someplace else.
Hope this helps!
