Also attaching the MS Build log. Do you need anything else from me?

Could you please advise about the following, where it comes from etc?
Missing class androidx.window.extensions.WindowExtensions (referenced from: androidx.window.extensions.embedding.ActivityEmbeddingComponent

Build04032022.zip

Steps to Reproduce

N/A

Did you find any workaround?

The app deploys and runs just fine.

Relevant log output

No response

I've already reported this some time ago via #6375, the app still works for me even if you see the messages.

[tipa]

I also see those XA4218 warnings that I think have nor seen before in VS 17.0
Also, deploying an app to the simulator becomes a gamble. 90% of the times when I change my .xml files (e.g. styles.xml) and try to build+deploy the app, if fails with:

========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
========== Deploy: 0 succeeded, 1 failed, 0 skipped ==========

yes, this is new, but I also get it in VS2019 16.11.10 and started since last AndroidX Nuget updates from end of last week.

@jpobst / @moljac would you know if there is something new about these libraries?

Would these be something new where you define <uses-library> for these in your AndroidManifest.xml? We might need to add some build-time support for this.

We are tracking this in #6652. The IDE team have an internal ticket which they are working on. I'll keep #6652 as up to date as I can.

@conceptdev Would you be so kind and help? Do you have any experience with this?

I cannot find these types in any of Google's AndroidX packages:

• androidx.window.extensions.WindowExtensions
• androidx.window.extensions.embedding.ActivityEmbeddingComponent

But the latest releases of AndroidX do now generally have a dependency on AndroidX.Window (via Xamarin.AndroidX.SlidingPaneLayout).

[conceptdev]

It's my understanding that the sidecar and extensions code are what we ship on device (ie. Surface Duo), to provide the OEM-specific implementation of the Window Manager dual-screen/foldable API surface. Other OEMS (like Samsung) would ship their own packages (again, in their OS).

Android native (Kotlin/Java) apps that consume AndroidX Window Manager do not reference these libraries via gradle. Not sure where these warnings are coming from in Xamarin.Android.

On maven.google.com I don't see corresponding packages there either.

[jonathanpeppers]

@jpobst do any of the .aar files contain an AndroidManifest.xml file with new <uses-library/> entries?
