I’m having trouble submitting screenshots for my app to the F-Droid directory. The app itself is published correctly, including the description and builds, but the screenshots aren’t. In the repository they’re located in the fastlane/metadata/android/en-US/images/phoneScreenshots folder and are named 01.png and 02.png.
At fastlane/supply/README.md at 2.28.7 · fastlane/fastlane · GitHub , it says “image names are irrelevant,” but at All About Descriptions, Graphics, and Screenshots | F-Droid - Free and Open Source Android App Repository , it’s strictly stated that the names must be 1.[ext], 2.[ext], etc.
I’ve read that F-Droid uses a metadata structure inspired by Fastlane (and is compatible with it in terms of directories and locales), but it doesn’t adhere entirely to it: in particular, they require strict sequential numbering for screenshots without leading zeros (1.png, 2.png, etc.). This is intended to simplify parsing and sorting in their fdroidserver system.
Is this true, and could screenshot filenames starting with zero prevent them from being uploaded to F-Droid, or is there another issue with the Fairphone Checkup app?
Is there any official evidence for this?
