Linking issue with Skiasharp on Android #259

Open neuroKip opened 3 years ago

neuroKip commented 3 years ago

Hello, I've installed the v1.0 android build via nuget (also tried v0.9.5) and tried the example on the wiki.

Unfortunately I'm getting the below linker error:

The "LinkAssemblies" task failed unexpectedly.
Mono.Linker.MarkException: Error processing method: 'System.Single SkiaSharp.SKFont::MeasureText(System.ReadOnlySpan`1<System.Char>,SkiaSharp.SKRect&,SkiaSharp.SKPaint)'
