content picker not loaded on ubuntu touch

[LiohMoeller]

On Ubuntu Touch it is not possible to add a zim file, as the content picker does not show up on a click on the 'Load ZIM' or 'Select Folder' Button.

@Jaifroid Can we still support Ubuntu Touch devices properly?

[Jaifroid]

@LiohMoeller @kelson42 The problem is that I don't have an Ubuntu Touch device to test on. I've no idea why the API has broken. I wonder if it's been restricted recently? We used to have someone willing to test, and we'd send them a package before release, they'd test it and also diagnose any issues. For the last several releases, we've been releasing blind for this platform. I'm not sure what I could do about it unless someone with a device were willing to take a look at the code and debug, or at least point me in the right direction. Possibly the File System Access API appears to be supported but isn't actually, and the fallback to the old File Picker isn't working.

@LiohMoeller Are you able to test on a device and help us a bit with the root cause analysis?

[LiohMoeller]

I can just send/donate you a device for development, if that would help.

[Jaifroid]

@LiohMoeller That's very kind, but let me see if there's a reliable simulator I could use first, as I think testing on real hardware would be a bit of a last resort (testing time is already quite onerous). I'll come back to you once I've done some research on this.

So it seems there is this Ubuntu Touch development kit: https://github.com/ubports/ubports-pdk . I'll see if I can get that to run in order to reproduce the issue.
