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. |
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. It would be perfect if this issue can be fixed, as the reader looks very very nice. |
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. |
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. |
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. |
I tried it, but unfortunatelly no success. I tried similar idea with Images/, but nothing again :-/. |
Hello, |
Hello, Thank you |
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. |
Hi zz0000000000, thanks for finding & writing here about the "sensybook"! I was missing an ebook reader on my B7722 very much. 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, 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 :-( |
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:
Would you be so kind and tell me your "setup" (FW+HW version, your card manufacturer/speed class)? Thanks and take care! |
dumbledore: Thank you for caring about us :). Maybe you can try contacting the maker of "sensybook" and ask him about this problem I think he will help us. maybe ask him to look at your code and see what is different from his. JimmyX32: I also have a no brand 8 GB MicroSD HC class 2, when I bought it I formatted it using the the phone it self. did you try using another SD card to see if you have a consistent problem. they are very cheap. buy a smaller one maybe like 4 gb and try it. PS. I never upgraded my firmware, I want to but I installed so many thing I dont want to lose them. :(, and I don't know what exactly the upgrades do, I am really angry at Samsung about that, they never explain anything and do not say what has changed in the updated firmware. |
Dear zz0000000000, I've tried my original 8GB/class 4 card (format in the phone, transferring the data using "Mass storage mode", but without success) - the phone hanged. Yes, it's true that Samsung never releases any information about new firmwares... really annoying. |
zz0000000000 : can u download any file or music or games in external browsers such as opera mini, uc . bolt etc?.... |
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 ;-)..
