The app is archived and will no longer be supported with new releases. It was just a (good) learning experience for me.
This is how the ubooquity api is made, I have zero control over this.
Try swiping up from the bottom of the screen, I think it is called immersive mode. Your system ui should show up again.
Epub and pdf are already supported. The epub reader is based on epublibDroid and the pdf reader is based on the internal comic reader.
You need to setup your server and possibly use the path "/opds-books/". All servers are different but it should be able to see your .epub and .pdf files.
This project is no longer in active development because I'm working on different projects. Thanks for checking out my app, there was a big need for a decent user client and I hope this fills it.
I was able to create a rar archive with winrar so that the server can successfully process it. The issue was I needed to select RAR4 archive format instead of RAR. I assume RAR refers to RAR5, so downgrading to RAR4 somehow works with Ubooquity. Whatever works I guess.
Ok I was mistaken, it is probably junrar unable to extract. I even tried to create the rar archive myself and it failed as well.
W/Archive: exception in archive constructor maybe file is encrypted or currupt
com.github.junrar.exception.RarException: badRarArchive
Archive -> Files [Valid]
Archive -> Folder -> Files [Not Valid]
It looks like your problem is the archive contains a sub-directory and then the files. The junrar fork is not relevant to your case. This could be fixed in the extraction process, but would require a bit more logic. Hope this helps.
I hope you don't have to rezip, that would be too much work. E-mail me a sample rar or set and I will be happy to test for you. sethchhim@gmail.com

The local database may have been corrupted. There is probably no way to recover that data.
If it was working before try to 'Clear Data' in the app settings to start over with a fresh database.
Sorry for the limited solution, I have dropped support because I do not think the Ubooquity project is active anymore. Good luck, hope you can fix it.
