No files are shown on Samsung GT-B7722

[JimmyX32]

Hi,

on Samsung B7722, I can see just the directory structure, but no files inside folders. This is a "feature" (i.e., bug) of this phone, as there are also other applications that have the same problem. However, there are also working ones - like BT File Manager 1.3.2 ;-)..

Have you by any chance transferred the files through bluetooth? I may be very much mistaken but it may be that your phone hasn't given them the right 'visibility'. Try transferring them by cable.

[JimmyX32]

Dear dumbledore, thank you for your reply. I transferred the files in "Mass storage device" mode. However, I checked the attributes and there were no files with "Hidden" attribs.
The problem is, that the AlbiteREADER (I tried 2.0.14 HD and 2.0.14 "Samsung Star" versions) shows just the top-level directories (e.g., "Mmc", "Images", "Other files", ...) and then nothing inside (neither other subdirectories, neither the files). However, everything is visible in the built-in file browser and also the files can be read (such as images can be displayed in the built-in photo viewer).

It would be perfect if this issue can be fixed, as the reader looks very very nice.

[dumbledore]

Well, the built-in browser and the photo viewer don't count. They access the files in a different way and there's no restrictions applied to them. Also, are you using the correct book format? Albite supports only epub, txt and html/xhtml so it wouldn't show files with the wrong extension.

[JimmyX32]

The file I was trying to access was a text file (filename: test.txt). Just to remind: in Albite, I can see just the top-level directories, but nothing inside. The top-level directories that are displayed: Mmc/, filesystem/, Photo/, Video/, Graphics/, Tones/, Music/ and Records/.

If I open the Mmc/ directory it is competely empty, even if the text file is located in the root of the card.
This means that even the top-level directories on the card are not listed at all. I use 2 GB microSD card, which is approx. half-full.

[dumbledore]

Very peculiar.

Could you try adding the file in Phone/Sounds/Recording (wherever the voice records are) and then try seeing if it would turn up in the Records/ dir.

[JimmyX32]

I tried it, but unfortunatelly no success. I tried similar idea with Images/, but nothing again :-/.

Hello,
I am having the same problem with my samsung b7722, after installing the book reader I am asked to give permission to read user data which I allow and I get the root folders but cant see any thing inside them, I even created a folder called books but it is not shown in the root folder view, when I enter any folder I get empty folder not even sub folders I created in them. I have the same problem with the following book readers " Foliant", "MTextReader", "Yong Reader". I also use "sensybook" it is very good and I can use it to read boots but it has a bug, when I close the application and reopen it again later the bookmarks I saved go to the wrong pages so I have to scroll allot to find the place I stopped reading. If you can help me please inform me. I like your book and interface. Thank you Best regards.

Hello,
I am sorry, my english is not well.
I am having the same problem with my samsung gt b7722, i see the directory's structure don't change, if i create a new folder Albite reader don't see it.

Thank you

[zz0000000000]

meliador88 I had the same problem with almost all the txt reads I could find. I think they can not access the folders because of security issue. The only reader I found to work with b7722 is "sensybook" search for it on google and download the latest version. have fun and good luck.
P.S. if this helped u add a comment for other people. :D

Hi zz0000000000,

thanks for finding & writing here about the "sensybook"! I was missing an ebook reader on my B7722 very much.
It is not very straighforward (at least when I tried) to Google the latest version. This is a link to the author's website

http://my.yanex.org/sensybook

IMHO the problem with not displaying the files is that the phone has a "special" implementation of Java (JSR-75). It's clear that it can read the files, however the file browser has to be programmed in some "special way" (even the "File Browser" example application from the Samsung Developer website doesn't work with the B7722!!?? - it has exactly the same problem).

Just to note, there is another issue with Java - it can read the memory cards just up to 2 GB (with FAT filesystem, not FAT32). Moreover, the card has to be fast enough (i.e., the reading speed has to be sufficient) - class 4 works best. But I guess this is important just for, e.g., navigation/mapping software, where large amount of data are read at once. If the card is not fast enough, the phone simply hangs - the only solution is to remove the battery.

Hi JimmyX32,
I have an 8 GB Mem card in my b7722 "sensybook" can read from it without any problems, I have installed many apps but didnt have any problem with them reading from the mem card. I have not tried a nav program with it yet though...

Anyway I am happy I could help.

by the way did u update the firmware on ur phone? and what kind of problems are u having with it?

Take care..

Guys, I'm sorry, but I haven't got a clue what's happening. I've just downloaded Sensybook and decompiled the class files so to look at the source. There's nothing special about the way File operations are handled. Nor is there anything special about the jar manifest. I'm just totally lost as to what my be causing this :-(

[JimmyX32]

dumbledore: Thanks for your effort! Couldn't it be then "outside the source code" - i.e., in compiler, some library, etc.? Anyway, the implementation of Java (JVM) on this phone is ... "unique" ...

zz0000000000: Thank you for the information! I finally found some time to test the Sensybook reader with my 8 GB card. It's of some unknown brand (=no manufacturer name is printed on it) and it's rated "class 4". I tried to format it using HP USB format tool, which does a deep format of USB drives (very useful for recovery of USB thumb drives ;-)). Then I copied a few text files to a directory called "Text". I got these results:

• reading a small file (I tried ~2 kB) is OK
• reading some larger file (The Hitchhiker's Guide to the Galaxy, part 5 - ~300 kB, plain text in Unicode) hangs the phone and it's necessary to remove the battery
  My FW is currently B7722XXJH3, FTA H/W rev. 1.3 (#*2222#).

Would you be so kind and tell me your "setup" (FW+HW version, your card manufacturer/speed class)?

Thanks and take care!
