android – Constructing SkiaSharp (Google Graphics/Drawing Library) for Unity utilization?

I’ve put in SkiaSharp by including SkiaSharp.dll and libSkiaSharp.dll in Unity from this web page’s prepackaged zip to my Belongings/Plugin folder and the next line to csc.rsp:

-r:AssetsPluginsSkiaSharp.dll

This works in Unity Editor on Home windows. I can entry the SkiaSharp features/courses. Nevertheless, after I construct to Android and attempt to run the identical features I get:

    2022/12/04 21:01:00.790 19171 19202 Debug Unity Did not load native plugin: Unable to lookup library path for 'SkiaSharp'.

I feel it’s because these information are from 2017 and the Android assist was added later. Due to this fact I have to construct my very own new dll information from the SkiaSharp venture.

I attempted cloning the github https://github.com/mono/SkiaSharp.git after which proper clicking and going to properties on the SkiaSharp venture lets me set the goal construct platform to dotnet2.1 which is what I would like.

I can then proper click on the venture and construct which efficiently creates SkiaSharp.dll. Nevertheless, it does no create libSkiaSharp.dll. The one references I see on the venture to this are that it’s made if you’re concentrating on netstandard 2.0:

Making an attempt to make use of SkiaSharp.dll with out libSkiaSharp.dll provides errors in Unity the place it says libSkiaSharp.dll cannot be discovered. As I perceive skiaSharp.dll is the C# code and libSkiaSharp.dll is the C++ code.

How do I construct the libSkiaSharp.dll file?

This website provides a find out how to construct SkiaSharp tutorial however I discover it not clear.

Thanks.
