Missing androidx.window.[extensions|sidecar] warnings #6809
Description
Activity
I've already reported this some time ago via #6375, the app still works for me even if you see the messages.
I also see those
XA4218warnings 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 ==========I also see those
XA4218warnings that I think have nor seen before in VS 17.0yes, 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?

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

androidx.window.extensions.WindowExtensionsandroidx.window.extensions.embedding.ActivityEmbeddingComponent
But the latest releases of AndroidX do now generally have a dependency on
AndroidX.Window(viaXamarin.AndroidX.SlidingPaneLayout).Reacted by MagicAndre1981It'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.
@jpobst do any of the
.aarfiles contain anAndroidManifest.xmlfile with new<uses-library/>entries?23 remaining items
We could remove these warnings, but I'm not sure that's the right path.
I would not do that. Warnings are not caused by us.
These libraries are passed to d8/r8 as a "reference" and they don't get included on the app. They are normally libraries that OEMs provide on certain devices. If we had them we could solve the
XA4218warning, and the d8/r8 warning.I found one library:
This leads to correct official location
https://maven.google.com/web/index.html?q=androidx.window#androidx.window:window-extensions
Are we supposed to be using this somehow? It's only in alpha.
No. It was bound when
androidx.window.*was in preview for Screen Duo work, but not touched/updated afterwards.https://github.com/xamarin/AndroidX/blob/main/config.json#L1325-L1348
see my comment:
the warnings are still present in Visual Studio Version 17.3.0 Preview 6.0

Thanks for the feedback, but Visual Studio version has nothing to do with this issue.
See: #6809 (comment)
Reacted by MagicAndre1981- changed the title
[-]VS2022 17.2.0 Preview 1.0 – Warnings not seen before.[/-][+]Missing `androidx.window.[extensions|sidecar]` warnings[/+]on Sep 14, 2022 I still get all the same warnings as to when I first reported it. I'm now using VS2022 17.3.0 Prev 1.1
These warnings are coming from AndroidX (
Xamarin.AndroidX.Window), VS updates will not fix it.I have the same warnings after upgrading the project to a newer Xamarin version using VS 17.5.2. I didn't have the
Xamarin.AndroidX.Windowpackage installed but still I got the errors. After installing this package just to test there were no changes in the build output log.Both warnings are still present after migrating a Xamarin.Android app to .NET 8
