How to debug Android "Upload failed" message


Some images from my android phone failed to upload. When I look at the “transfer list” in the Android client and select “upload list”, I see a bunch of images marked “Upload failed”. It doesn’t look like there is a way to see details of the error from the client (is there a way)? So I checked the server logs at ./logs/seafile.log, as well as all the other log files in the logs folder (controller.log, entrypoint.log, seahub.log, etc.), but could not find any line-items related to the android failures.

Any idea how to debug this properly? I think I need to see log details on the android phone itself.

Thank you.
