Android Notes Role API

Use case or problem

Android 15 is gonna introduce an API for note-taking apps to be able to get called directly from the lock screen and also to hover over other apps and then get minimized into a floating bubble again. This would enable (afaik tablet only?) users to have instant access to obsidian and be able to minimize the app right away again

Proposed solution

to make that happen, the app needs to the “NOTES” Role (see: Android roles  |  Android Open Source Project)
in order to support this

See google keep as an example, the first screenshot shows the floating bubble on the left edge of the screen, tapping on it is supposed to launch the note-taking activity, this is not the case since the screenshot is old
