I remember they had a blog post about this. A big source of confusion is that Uber already had this feature on their notifications so a lot of people thought this feature existed already. But it turns out Uber had to do a lot of custom work to do it in their app, and now Android has made it an easier and standardized API.

If this doesn’t sound like anything new to you, I don’t blame you. After all, rideshare apps like Uber have already been showing notifications like this for years now. Uber had to do a lot of custom stuff to make its notifications look like that on Android, though. Google has basically created a standardized version of what Uber’s been doing. With the new progress-centric notifications in Android 16, any app can create notifications like Uber.
Relatively stable? I’ve seen some complaints, so I haven’t done the update yet. But Google considers it to be stable lol.
