OK, tried to understand, but no chance ..., my question, do you think, by modifying the one or other file "manually" on a K4, coverview could be activated there as well? Where do I have to look for to give you an idea, if this could work?

I repeat: I don't own a K4, so I have no idea

The first thing would be to port the JBPatch core to the K4.

Then you could decompile the Home Booklet and check whether it looks anything like the one of the K5 (in particular, if you find the strings "LIST_VIEW_MODE" and/or "COVER_VIEW_MODE") in there, it's probably possible. But it still wouldn't be a piece of cake, because you'd have to do all the reverse engineering work again (well, if you're lucky, you might be able to benefit from some of the stuff I did for the K5).

Remembering from back when I got a K4 image for testing, the K5 and K4 jars are radically different (probably an entirely different code base), so the chances to actually find substantial (code) similarities between these framework is minimal.

Does anyone know why amazon book covers look bigger than calibre generated book covers?

Just an idea but maybe your computer has a higher resolution then 600x800. Just messing with you . But your computer most likely does have a higher resolution and because of that (depending on your monitor size) the images will look smaller. Right?

The cover image is stored inside the ebook file. Calibre has some rules that it follows when adding a cover image to a converted ebook, as documented here:
http://manual.calibre-ebook.com/conversion.html

Amazon may use different rules when converting ebooks, giving a different cover image size.

Give it a little time after loading, like I do in my Kindlets with the splash screens. Alternatively, try to do it in the onStart() method instead of onCreate() (untested).

I don't know why that is, but immediately trying it in onCreate() seems to fail most of the time. And of course, be sure to follow the syslog and /mnt/us/developer/AppName/work/crash.log.

@so is there a way to change the calibre-generated covers so that they are equal in size to that of amazon book covers?

Well, I call it from onStart() (as in CollectionManagerKindlet.java, so I guess it is tested ). Adding "Thread.sleep(1000);" around it changes nothing. It doesn't crash, and I'm not sure what to look for in messages. They are pretty verbose with ;debugOn.
Is it too much to ask for sample app, that works for you?

If you had read the calibre page at the link that I provided in my previous post, you would have known that the answer to your question is "yes" and you would not have needed to ask it here.

Go back and read the calibre web page at the link provided in my previous post. Pay attention to the fact that calibre can insert an cover image of your choice into the ebook. You can resize an image before giving it to calibre.

That's a pretty minimal application with only two classes.

Possible idea for patch

After upgrading from a Kindle Keyboard to a Kindle Touch in March, I have to admit there's one feature I do miss -- the progress bar at the bottom of the screen showing where you are at all times in a book.

If the TOC was formatted correctly, the chapters would also appear on the bar as nodes, which I found useful, too.

The Touch does show a progress bar, but only for periodicals, as far as I know.

IMHO, it would be great to be able to have this old functionality back, at least for those who miss it.

I'm a complete and utter noob when it comes to Java (but am planning to have a look at your tutorial, ixtab! ). Anyway, just thought I'd put the idea out there.

@veezh/ixtab: FWIW, there was a reader setting to enable/disable the progress bar in FW 3/[4?]. I don't remember if it was properly hooked to anything, but it existed .
