Announcement by the creator: https://forum.syncthing.net/t/discontinuing-syncthing-android/23002
Unfortunately I don’t have good news on the state of the android app: I am retiring it. The last release on Github and F-Droid will happen with the December 2024 Syncthing version.
Reason is a combination of Google making Play publishing something between hard and impossible and no active maintenance. The app saw no significant development for a long time and without Play releases I do no longer see enough benefit and/or have enough motivation to keep up the ongoing maintenance an app requires even without doing much, if any, changes.
Thanks a lot to everyone who ever contributed to this app!
Stable bindings doesn’t mean open source, so I don’t see how that tells you it’s still on the table
They’re moving a lot of code to this internal core, which means this core is unstable. It’s pretty common for projects to hold off on making code public until it’s reached a certain level of stability. I’m guessing they’re not interested in accepting patches, due to the high level of churn from the dev team. Once that churn dies down, there’s a chance they’ll reconsider and make it FOSS.
I’ve seen this in a number of FOSS projects, and it’s also what I do on my own (I don’t want help until I’m happy with the base functionality).
So that’s why I hold out hope. We’ll see once the churn on that internal SDK repo dies down.
