Wordwise Generation for Kindle android app #11

Open Tikotik opened 6 years ago

Tikotik commented 6 years ago

Is there a way to add the generated wordwise kll file for android kindle app? I observed that wordwise information for the app is stored at /data/data/com.amazon.kindle/databases/wordwise/wordwise.kll.en.en.db as a single file for all downloaded books, And Wordwise.override.[asin].en.db - maybe for matching above file to each book

Can you look into it in future for matching sideloaded books with wordwise.kll file? Thanks.

It appears that the Kindle app looks in /data/user/0/com.amazon.kindle/databases for a file named WordWise.en.[ASIN].[database_name].db (where the database name usually starts with CR_ for Amazon books). You can get the dbname with the mobitool included, just run mobitool-win32.exe -i on your book and it's the first field in the Palm doc header:

Full name: Fleet of Worlds

Palm doc header:
name: CR!25XE4QN50Q2TQDG810J31GQY6Y9D

So for this book I had to use WordWise.en.B000UZPHTE.CR_25XE4QN50Q2TQDG810J31GQY6Y9D.db

You need root to access the /data/user folder (which you have but many don't).
You will also have to change permissions/security context on any files you move to that folder, from a terminal emulator app or via adb shell

su
cd /data/user/0/com.amazon.kindle/databases
ls -Z  (to get proper group & security context)
chown u0_a93:u0_a93 filename (where u0_a93 is the group from your ls -Z)
chcon u:object_r:app_data_file:s0:c512,c768 filename
(again, take the context from your ls -Z, maybe it's the same for everyone?)

The override file is different and seems to just provide a mapping for original/corrected terms.

No luck. What I did:

  1. grabbed this test book
  2. Ran the wisecreator, now I have a modified mobi (472KB from 517KB) and the file: LanguageLayer.en.4312fce0-d09d-4ab3-bbc1-3407e6ff3f08.kll
  3. Renamed the above file to WordWise.en.4312fce0-d09d-4ab3-bbc1-3407e6ff3f08.Ender_8217_s_Game.db based on your suggestion. I hope nothing wrong with directly changing .kll to .db
  4. Pushed the above db to /data/user/0/com.amazon.kindle/databases and changed permissions. (although I am not getting any group info from ls -Z, I ran both chown and chcon)
  5. Finally pushed the .mobi file to Android/data/com.amazon.kindle/files
  6. Still kindle doesn't recognise its wordwise.

Did you do the permissions stuff too (from a terminal emulator on the phone or through adb)? Edit: Sorry, missed the part where you said you did. Can you paste the line from ls -Z of your file? Edit 2: Looks like I was wrong about the dbname portion, it's actually the GUID, BUT it also looks for one in the format WordWise.en.ASIN.db! (still within the /data/user/0/com.amazon.kindle/databases` folder though). I started fresh with a different book and was able to get it working there as well, but the locations of the highlights were off for some reason.

Great. Working after renaming it. Although I am not suffering with location offset for this one file, I will update after multiple tries. So, after permission changes from terminal emulator and renaming, output of ls -Z for my file is: u:object_r:app_data_file:s0:c512,c768 WordWise.en.4312fce0-d09d-4ab3-bbc1-3407e6ff3f08.db

Nice. Good to know the security context is the same for yours too.
