Is there an event for app to know open or close some hardwares' permission from charm bar(for example: camera or microphone)?


  • Hi,

        After install app which use camera or microphone and run it the first time, the system will give the tip and we can choose agree or deny using the device. Or we can open or close the permission from the charm bar, how can app know this?

  • There is no notification. The app should assume it can use the device but handle failures gracefully.
