In my continuing efforts to use the Droid for reading, I've moved on to comics: I know it's not quite the same - but it is reading nonetheless.
The two applications I've spent the most time with are Robot Comics' Droid Comics Viewer or ACV and one called Vintage Comic Droid.
ACV is a CBZ reader for the Android platform (it reads CBR as well but it's buggy and slow, so I would recommend sticking with CBZ). It's a free app, which is nice, and Robot Comics provides free and paid content in the Android Market. The viewer itself works well; I was able to load a 170MB CBZ file without problem. It also remembers where you are in a comic, which is helpful when you need to exit the application.
It has a bare bones front end, but is very customizable. You can adjust the controls and the Droid's high resolution screen makes comics surprisingly readable even at a very small size.
The one annoyance I've found is that sometimes pages take a while to load.
It's a very good app if you already have a comic collection in CBZ (you can get some
here).
The next app I tried was Vintage Comic Droid.
Once again, this is a free app in the Android Market (ad-supported). Installation was a bit of a pain, as the app required me to download two additional graphics files from within the app before it would do anything, and I kept having server issues. However, once it was done I was quite pleased with the result.
What I really like about this app is that it includes free download access to approximately 3,000 public domain comics. If you like old comics, this is the app for you. There is a download limit, I seem to get about 10 downloads per day, but that's not bad.
The library interface is great, looking like a bookshelf full of comic boxes.
Unfortunately, the reading interface isn't quite as good as that in ACV. among other things, it's much less customizable. Also, if you use the touch screen for navigation, it pulls up a control overlay which I find distracting. Luckily one can use the d-pad to navigate if you have the keyboard open: down arrow to scroll down (helpful if you're in landscape mode) and center button to page forward. Please note, this is not documented in the app.
Downloaded comics are stored as .bin files in a hidden folder in your SD card, and are not viewable from most Android file managers. You can see them if you mount the SD card on your computer, and since they are stored in sub-folders by title it's easy enough to manage them that way. This is handy as they can be fairly big files and I have not been able to find a way to delete them from within the application.
Still, I do like the application a lot, and it's very stable.
