I use the zoo for zetero program on my Onyzx Boox device. Markings and notes made in pdf files on my tablet are not synchronized with the zotero program on the computer. On my Onyx, is it possible to open pdf files with zotero and not with neo reader?
OK, we don't have anything to do with the Zoo — that's a third-party app. An official Android app is in development.
If the PDF reader you're using saves changes back to the PDF and Zoo uploads the PDF, the updated file will sync to the desktop app and the annotations will be visible in the built-in PDF reader. That's about all I can tell you.
Thank you very much for your answer. I started using the Zotero app today. It's a really good app. I have used some applications called Men.. and end.. before. I wish you continued success. In the mobile application you will make, the synchronization of the changes in the pdf files with the zotero on the computer will bring you a new age. Kind regards
