Hi,

Thank you for your work, but this has already been implemented by #1238 and merged into dev. cc @peanutwolf

I'm sorry for that, I did not really mention that dev is the development branch.
To try to avoid this in the future, I just added a branches section in BUILD.md. Maybe I should also add a pull request template (but it's too late to mention it there, if people have already done their work on master).

Anyway, your code contains changes that are not applied on dev, like registerRotationWatcher().
Could you checkout/test dev and propose the missing changes, please?

What multi-display device do you use? (I have no way to test this feature.)

Hi, yes that was funny :) no worries. I will create pull request for missing part.
I use proprietary 3-display device with touch on 2 of 3 screens, running Android 10.
