I'm particularly interested in the compatibility between Wayland and Android (although I'm also curious about X and Android).
For example: does a Wayland window manager work on Android? Conversely, can you get Android apps to work on Wayland (or X) window manager?
And overall, is there a single window manager on Android that is near universally used, or are there a multitude of them (just like on linux, where there is a multitude of window managers out there used across the various distros)?
