BackHandler does not catch backs via swiping (in SwipeDismissableNavHost), as it does in mobile side. Now I need to do some arrengements onBackHandler, how could I do this in wear OS?

Hi - swiping back is handled as navigating back to the previous screen in SwipeDismissableNavHost. What's the functionality you're trying to get?

If you are trying to add additional handling when the user swipes to navigate back, there's some code here that shows how to do that: https://issuetracker.google.com/issues/292590712#comment4

Hello Steve. I am looking for a BackHandler which handles swipe back events too. Right now back events via swiping is not caught by BackHandler, so I can’t override the process for wear OS (as I do in mobile development).

Hmm that might work for me too

It’s not a stable solution, but definitely a better workaround than mine. Thank you so much Steve

Glad that helps. Interested to know why you describe it as not a stable solution?

I mean, as in traditional development, or Jetpack Compose for mobile, I was expecting that it catches all the back events: https://developer.android.com/jetpack/compose/libraries#handling_the_system_back_button

However, it miss swiping back event

Yep, Wear OS doesn't trigger any of the system back APIs that exist on phones, tablets, TVs, etc. - neither the (now deprecated) onBackPressed() or anything else built on that infrastructure like BackHandler. That's always been the case.

The Wear team is aware (ha) of that difference, but it is a difference that is baked into the current version of Wear OS itself, so even if it were to change, it would only apply to that hypothetical newer version of Wear
