Issue while creating Json file

[Wordcounter]

I'm getting error as per screenshot attached, when trying to run through Command prompt. When trying through run through opening the .jar file, I get similar error as below:

Please advise.

Your backup probably contains the manga images (which interferes with the decoding), delete them and clear cache then try to redo the backup.

I'm having a similar issue. The problem is that your inflater needs to be updated. I just downloaded abe-all.jar and it was able to successfully decompress my .ab archive where your tool keeps crashing. That's after deleting all MR downloads, turning off the download feature, force-stopping the app, and dumping the cache before creating the backup file. Even in this state, I get

Exception: For input string: ""

Suggestion: Is there any way you can allow the tool to work from an already inflated .tar file as well as from the deflated .ab file? At least then, even if there's something you can't fix about that quirky algorithm Google chose, we would still be able to use the tool after manual inflation.

The issue is that there seems to be two different ab formats, the ab file i got from my phone did not work with abe-all

If you have the tar file already, it should be trivial to open it in an archive manager like 7-zip and manually extract the db file directly. In that case you can just open it in the tool and get your json file.

Manually converting to TAR and using the DB file worked well.
Format probably depends on which ADB or backup tool (Helium) you use.

That's what I ended up doing. After posting that comment, I looked at the repo and noticed that the program can accept the .db file. So I just extracted it. Now all but about 15 of my 450+ manga are in Tachiyomi. The only not-so-nice part about it is that the "last read" information didn't seem to come along with it.

Probably. I couldn't get Helium to backup MR. It's the only app that Helium wouldn't work on. I also couldn't get the OS to backup MR. None of my phone backups contain MR. I could only use adb backup to get it.
