I have update target framework from net6.0-android33.0 to net8.0-android34.0 and I have the same issue.
The error is: Could not find Android Resource '@styleable/SKCanvasView'. Please update @(AndroidResource) to add the missing resource.

Also happens here.

Steps to Reproduce:

1. Create new Maui project (.net 8)
2. Add "Particle.Maui" nuget

nothing further.

When upgrading from .NET 6 to .NET 8 on my project using outdated packages. I had to add

<declare-styleable name='SKCanvasView'> <attr name='ignorePixelScaling' format='boolean'/> </declare-styleable>

to Platforms/Android/Resources/values/attrs.xml to get the project to build and deploy.

After updating all packages, I was getting the issue mentioned in OP. I removed this from attrs.xml and stopped getting the error.

Edit: It seems to work sometimes and not work other times, as OP.
Here is where the original fix was that worked for me.
mono/SkiaSharp#2444 (comment)

Still exists with 8.07 Maui.. Make sure to change the attrs.xml build action to AndroidResource

I have this intermittently. If it happens, my solution won't build for an hour or so, and then it will start building again. There must be some caching involved, but it isn't related to the obj or bin folder, because removing those entirely doesn't change it.

Also, it only starts when I make a clean build, on my local machine (Debian Linux), and never in CI (also Debian Linux).

Verified this issue with Visual Studio 17.10.0 Preview 2 (8.0.14 &8.0.0-rc.2.9530). Can repro it

Sometimes running dotnet clean (which doesn't clean everything) helps me resolve this error when it occurs.

Updating the <PackageReference Include="LiveChartsCore.SkiaSharpView.Maui" Version="2.0.0-rc2" />fixed the issue

[Flaszlo1]

It seems, if you install this package:
SkiaSharp.Views.Maui.Controls.Compatibility, solves the problem.
