I'm developing a class library for windows 10 universal apps (mobile and desktop device families only). I need to invoke an event if the user has been idle(no touch, mouse move, key press etc) for x number of seconds. This method can be used to solves this problem on android. But I couldn't find a solution on windows UWP.
Is there an API available in UWP to achieve this?
You can detect global input with various events on the app's CoreWindow:
Touch and mouse input with CoreWindow.PointerPressed, PointerMoved, and PointerReleased.
Keyboard input: KeyUp and KeyDown (the soft keys) and CharacterReceived (for characters generated via chords & text suggestions)
Use these to detect the user is active and idle out if it goes too long without any of these events.
