Bubbles is a windowing mode feature that offers a new floating UI experience similar to the notification bubbles API. Users can create an app bubble on their phone, foldable, or tablet by long-pressing an app icon on the launcher.

On large screens, there is a bubble bar as part of the taskbar where users can organize, move between, and move bubbles to and from anchored points on the screen.

This experience is available to all apps that comply with the existing best practices for multi-window support. Developers should follow the guidelines for supporting multi-window mode to make their app work correctly as a bubble.
