AndroidX Parent class vtable failed to initialize, due to: VTable setup of type AndroidX.SwipeRefreshLayout.Widget.SwipeRefreshLayout

Version Information

Visual Studio version (eg. 16.8 or 8.8): 16.10.4
Xamarin.Android version (eg. 11.1): 5.0.0.2083
Using AndroidX or Support Libraries: Xamarin.AndroidX.Core 1.6.0.1

Describe your Issue:

My android app crashes in Release mode, So I started to figure out why. Seems to be an issue with this package and the Linking Behavior set to "SDK only"

Parent class vtable failed to initialize, due to: VTable setup of type AndroidX.SwipeRefreshLayout.Widget.SwipeRefreshLayout failed assembly:Xamarin.AndroidX.SwipeRefreshLayout.dll type:SwipeRefreshLayout member:(null)

Steps to Reproduce (with link to sample solution if possible):

Enable "Linking Behavior" to "SDK only" and run the app on a real device. It crashes on startup with this exception.

Include any relevant Exception Stack traces, build logs, adb logs:

Yes, but the issue is closed, while it's not fixed. So I opened a new issue for it 👍🏻

Also experiencing this issue, runs fine on emulator but when I send it to AppCenter to be built with linking enabled, I see this same issue when the build is tested on a real device. That is with v1.6.0.1.

Please could you provide minimal repro sample?

Sorry for the late reply. I try to get a sample for you.

I experienced this issue as well. Discovered that all pages containing the ListView element would crash OnAppearing. Solutions which worked for me were:

Utilizing a CollectionView instead.
Or upgrading the Android target framework from v.11 to v.12
&/or upgrading all AndroidX libraries within NuGet package manager to the latest (June 2022 release)
