[fbreader] Failed to download books on FBReaderJ

[michael schiller]

Hi

I downloaded the source code and was able to build the reader under
android-7 platform.
When installing the reader on a device, everything worked fine except
for the book download.
After debugging I found out that the reader can not create any file or
directory on the SD card file system.
The same reader downloaded from the APP Store works fine.
Any clue for what is the problem?

Michael,

AFAIK there is no tricks we use during package building. The only
idea: we use our own generated key for signing the package.
May be sdcard is read-only for applications signed with a standard
debug key?

Please let me know what is the solution -- that's really very strange.

Best,

It's very interesting.

There is another place in FBReaderJ code where application writes data
to files.
This is in the org.geometerplus.fbreader.network.NetworkImage class.

Can you check, if application can create file and write image data to
it in the synchronizeInternal(boolean) method.

You can check it by opening network catalog with books, that you
haven't opened before (i.e. there is no cached images for books
covers). If you can see books covers, than application is able to
write images to your SD card.

If application can create file and write image data to it, than there
must be an error in the BookDownloader code.
If it can't, than probably there is a problem with security.

If there is exception thrown while fbreader attempts to write data to
file, can you send me its stacktrace?

It will be built on android-4 with ant.
Try again with android-4 platform.

Hi

I solved the problem by adding a permission (WRITE_EXTERNAL_STORAGE)
to the manifest.
Not sure why it is not already defined.

Thanks

Michael,

Thank you for the information. I've added this permission in the
manifest. :) I think it works in our compiled version just because we
use old (android-3) platform: we'd like to have an application that
works on old phones too.

Best,
