问题
I have been wondering if there is any way in the android API (or any other lib/framework) that can help me to detect if my device screen is mirrored using WiDi,Miracast or MHL or basically any other technique for mirroring your screen.

回答1:
You may navigate through the list of all device display and get flags on each for finding one with, maybe, VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR ? Not sure but a few trys should allow you to figure out which ones will do it.
cf: DisplayManager and VirtualDisplay documentation

I'm not sure what you are trying to achieve, but if you simply want to disable screenshots and such, you can use FLAG_SECURE.
