camera-samples VS wear-os-samples

For the device formats, what you get on CameraX should be what you get on Camera2, but you can verify with the Camera2Video sample app. It lists the available resolutions and framerates (which notably calculates it in largely the same way that you're already doing).

It's been many years since I used camera APIs, and only camera1. I don't have experience with camera2 and cameraX. The android camera docs https://developer.android.com/training/camerax/choose-camera-library lists the available libraries and in additional resources at bottom of pages, there are samples available. You probably need https://github.com/android/camera-samples/tree/master/Camera2Basic or https://github.com/android/camera-samples/tree/master/Camera2Extensions

https://github.com/android/camera-samples They have both Camera2 and X code.

Have you checked out the official samples: https://github.com/android/camera-samples/tree/master/CameraXBasic

Using DataLayer to transfer data from phone to your watch app. Check here wear-os-samples/DataLayer

Here is a really good repo by Google filled with WearOS sample projects. Helped me a lot with setting up communication between watch and phone. This is also a good starting point to understanding how these apps work. https://github.com/android/wear-os-samples

There are plenty of open source watchfaces out there. Check out this github repo by Google. It contains best practice examples all around wear os including watchfaces.

So I'm looking for good sources on how to use the new jetpack apis. So far I only found this sample project.

I think for Android based smartwatch, you could read something here

Main documentation about how to make watch faces under Wear OS seems to be the WatchFaceKotlin example. This example contains borders around complications. Some installed watch faces don't have borders around complications.

I converted my codebase to Kotlin a few years ago, but I am struggling to move to new wear libraries. There is so much work to do, because Google, in their immense wisdom, decided to change everything. And don't even get me started about the Decomposition API (option to add second hand in ambient mode). I opened this issue almost a year ago and got no answer. https://github.com/android/wear-os-samples/issues/85

Tried this sample from Google: https://github.com/android/wear-os-samples/tree/main/WatchFaceKotlin
