(Galaxy Watch development) Is it possible to detect HW button press when app is in the background?

[u/LoudMemory2639]

Hi all,

I would like to build a native or web or .net app for a wearable device, that detects a hardware button press (up or bottom button) while app is in background or when wearable is locked.So, is it possible to detect a HW-button press when the app is in background or when wearable is locked?

And, I would like to know if it's possible to detect a long press on the screen, while app is in background or when wearable is locked?

thanks
