WatchMaker終了だな

"Google and Samsung's watch face collaboration, focusing on the new Watch Face Format (WFF), is nearing its completion. Specifically, by January 14, 2026, users will no longer be able to install legacy (AndroidX/Wearable Support Library) watch faces from the Play Store. Developers will also lose the ability to update these legacy watch faces. While existing legacy watch faces will continue to function, they won't receive further updates or be monetizable through new purchases or subscriptions, according to Android Developers Blog."
