• I've searched for similar issues and didn't find a duplicate.

• I agree to follow Nextcloud's Code of Conduct.

Steps to reproduce

1. Login into Nextcloud from the Nextcloud Android App (see screenshot loginscreen in the attachments)
2. Try to download the PDF of the Nextcloud manual by selecting it.
3. In the screen (which appears) the content is not loaded (see 2nd screenshot), not even after a long waiting time.
4. Now I try to add a comment by the box in the upperhalf of the screen (see 2nd screenshot again).
5. After pressing the arrowbutton, the JAVA error (see errortext) appears.

Remark: Downloading by the Windows client does work as expected!

Expected behaviour

I expect to have the manual downloaded to my phone (seeing that I tried this on my Android phone)
Further I expect my comment is added after pressing the arrow button.

Actual behaviour

The manual pdf is not downloaded and after pressing the arrowbutton the JAVA error appears.

The commenting matter is covered in #12353. The PDF/download matter: I cannot reproduce this behavior unfortunately.

• Is this a brand-new installation of the client?
• Can you try setting the PDF to Download? (i.e. Select the file then using the 3 dots menu then choose Download). Does the icon receive a green checkmark?
• Are you able to view, create, and edit other types of files in the client?
