[Fire TV Themes and Apps] tarvoke:
UPDATE: found copies of older versions of Kindle Reader App (needed for a 2.2 tablet of mine - anything newer not only does not run, sometimes when it crashes it corrupts the system partition and almost-bricks the thing. but anyway...)

so I just now installed Kindle_3.4.1.1.apk, which does not use underlying amazon framework, it does its own signin. and guess what? other than being 3 years old, it works perfectly!!! I might try searching more to see if there is a latest version of old v3, or early versions of v4, that do their own signin and don't use the framework, but for now I am slightly happier (but still no thanks to amazon)

and it shows up as a completely separate device, "Yourname's 2nd Android Tablet", not "Yourname's Fire TV" - which makes sense given the two completely different forms of signin.

/UPDATE, and now back to original post...

this morning I checked and there was an updated kindle reader app on google store, dated 4/22 (I believe last time I tried was 4/8)

same result, it understands the amazon framework that's running, so already knows my account and can sign me in. but again now with this newer version, no still books show up. also noticed this time, if I go to amazon webpage of my kindle books, they all have an option for "send to device" ... I can send to my android phone, my PC, anything I installed kindle reader on. but the dropdown of devices does not ever include firetv.

I used the built-in "Send Feedback" part of the kindle app, on the firetv, to say how disappointed I was that something called "Kindle Fire TV" (that is the actual name of our device, for those unaware) was unable to read kindle books.

it was nice of Amazon to reply so quickly, however their reply mainly seems to be "we'll pass your suggestion along, but in the meantime why not buy one of our kindle tablets?"

I wish I had thought to mention how a lot of people with disabilities would very much like to be able to use a big television and firetv to read books, not some small tablet. (I also wish I had explicitly mentioned I was sending my feedback from kindle reader running on firetv)

even more funny, the "cloud reader" works perfectly fine in chrome on my firetv - of course, I had to turn on "request desktop site"... otherwise read.amazon.com says, "I see you are using an android device. you cannot use your android browser for cloud reader, but why not click on this link to the google play store and install kindle reader app?" - thanks guys, simply hilarious!

I don't know if a lot of people want to read their kindle books on firetv, but if you think you ever might, please consider writing to amazon (the feedback button in kindle reader app works great!!!) - thank you ;)

Hello,

I'm sorry if you are not happy with the Amazon Fire TV you've bought.

Unfortunately, Fire TV won't run any Kindle application to read eBooks.
We've applications designed for other devices so that you can enjoy reading kindle books.

Amazon Fire TV can actually be used as an additional “Big Screen” option for using Second Screen and Display Mirroring features to display content from Kindle Fire 3rd Generation tablets to your TV screen.
Amazon Instant Video movies and TV shows, and Photos can be displayed with Second Screen to Amazon Fire TV.

However, using Fire TV to read Kindle books is a suggestion that can be worked upon.
I'll pass this on to our Kindle Development Team and I'm sure this will be looked into.

We'll consider your feedback as we plan further improvements.
Customer feedback like yours is always important to us.
I'll be sure to pass your message along to the appropriate department as we continue to improve the Kindle experience for our customers.

If you've any concerns/suggestions/complaints, then please let us know. We'd be more than glad to assist you.
