Accessing Foldable Sensors from your applications
In order to currently access the sensor data given by the foldable sensors, you need to use the following apis:
- Windows.Devices.Sensors.HingeAngleSensor*
- Windows.Internal.Devices.Sensors.FlipSensor* (2)
- Windows.Internal.System.TwoPanelHingePostureDevice* (2)
(2): These apis require the use of an externally sourced winmd available from https://github.com/ADeltaX/InternalWinMD/blob/master/%23winmd/Windows.Internal.Devices.Sensors.winmd
In the future, further apis will be functional (specifically under the Windows.System.Preview namespace). Consider this an early "thing".
The following API may be used to determine if...
