I have the following issue with the PDF Viewer app. Would anybody be able to see if they can reproduce it?

Description of issue

PDF Viewer app crashes when trying to open PDF file saved in Proton Drive from the AOSP Files app

Expected behaviour

PDF Viewer app displays contents of PDF file

Steps to reproduce

  1. Install GrapheneOS PDF Viewer app
  2. Install Proton Drive and save a PDF file there
  3. Open AOSP Files app
  4. Open Proton Drive "folder" from side menu of AOSP files app
  5. Click to open saved PDF file
  6. PDF Viewer app opens. Header of the app is visible. Content of PDF not visible.
  7. Delay of one second
  8. PDF Viewer app crashes

Notes

  • PDF Viewer app works as expected outside Proton Drive
  • MuPDF app works correctly. It opens PDF file from Proton Drive from AOSP Files app
5 months later

Also able to reproduce this issue.
Perhaps it has to do with files stored in the cloud. Could other users try other cloud providers?

    Lusca Good suggestion to try with another cloud provider.

    I repeated the exact same steps above but for Google Drive rather than Proton Drive. I could open a PDF file with no issue, and no crashing.

    So it seems to be a Proton Drive issue.

    Is anybody able to test Proton Drive on stock android OS?
