Syncthing Android App Discontinued

Thank you google for killing yet another great app. There should be special category for apps that are "Done, Complete, Perfect as is", as with decent backwards compatibility on Android there should be no issues with them. I bet apk compiled for Android 1 still runs perfectly on Android 15.

Android is one of the few platforms on earth where anything interesting actually could be done and finished, since they have actual stable API levels unlike Linux.... And they don't allow it

Depends on the exact functionality. I'm aware of some battery events you could listen to from the manifest file in 2, that were removed at some point after that and now you have to listen for them from a running service. It broke a bunch of battery monitoring apps when it happened.

Also with services, there's additional requirements to keep them running that weren't there early on.

The problem, as most of the time, are bad actors. Which is the reason some permissions, SAF, disallowing targeting lower SDK versions etc were introduced on the Play Store.
