Sync to local file on Android

[debilin]

Describe the feature you'd like to request

I saw that this has been requested before in #1384 #1217 #1086 which cannot be done in browser extension. My request is to do this for the Android app only. Since desktop already has LoFloccus, SyncThing can then be used to sync across all platforms.

Describe the solution you'd like

Allow syncing to local file on Android. I suppose this is possible with Android app since it's not a browser extension.

Describe alternatives you've considered

None

Hello 👋

Thank you for taking the time to open this issue with floccus. I know it's frustrating when software
causes problems. You have made the right choice to come here and open an issue to make sure your problem gets looked at
and if possible solved.
I'm Marcel and I created floccus and have been maintaining it ever since.
I currently work for Nextcloud which leaves me with less time for side projects like this one
than I used to have.
I still try to answer all issues and if possible fix all bugs here, but it sometimes takes a while until I get to it.
Until then, please be patient.
Note also that GitHub is a place where people meet to make software better together. Nobody here is under any obligation
to help you, solve your problems or deliver on any expectations or demands you may have, but if enough people come together we can
collaborate to make this software better. For everyone.
Thus, if you can, you could also have a look at other issues to see whether you can help other people with your knowledge
and experience. If you have coding experience it would also be awesome if you could step up to dive into the code and
try to fix the odd bug yourself. Everyone will be thankful for extra helping hands!
One last word: If you feel, at any point, like you need to vent, this is not the place for it; you can go to the forum,
to twitter or somewhere else. But this is a technical issue tracker, so please make sure to
focus on the tech and keep your opinions to yourself.

I look forward to working with you on this issue
Cheers 💙

I also want this to sync lofloccus and Android, currently there is no way to use lofloccus and sync with Android (such as via syncthing) unless you expose the lofloccus webdav server to the Internet (dangerous)

Unless someone knows of an android app that can emulate a dav server?
