Is SkiaSharp 3.0.0-preview2.1 using Skia or Android Canvas on Android in .NET MAUI?

[TommiGustafsson-HMP]

We are trying to delve into the source code of SkiaSharp in order to optimize our .NET MAUI application (.NET 9.0-preview2) for Android (we are migrating from Xamarin.Forms). However, the code is not very straightforward to read.

Source Code, Source Folder

When I check the source code and the source directory, I find SKCanvasView and SKGLView:

• source/SkiaSharp.Views.Maui/SkiaSharp.Views.Maui.Controls

These seem to use handlers found in source/SkiaSharp.Views.Maui/SkiaSharp.Views.Maui.Core/Handlers, which refer to:

• source/SkiaSharp.Views/SkiaSharp.Views/Platform/Android

These classes seem to use Android Canvas.

Decompile

However, when I decompile the SkiaSharp assemblies, which are included in our application using Visual Studio, I get classes that reference SkiaApi, which would hint that these assemblies use Skia. The decompiler says:

#region Assembly SkiaSharp, Version=3.0.0.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756
// C:\Users\TommiGustafsson\.nuget\packages\skiasharp\3.0.0-preview.2.1\lib\net7.0-maccatalyst16.1\SkiaSharp.dll
// Decompiled with ICSharpCode.Decompiler 8.1.1.7464
#endregion

using System;

namespace SkiaSharp;

public class SKCanvas : SKObject
{
...
        private unsafe void DrawImage(SKImage image, SKRect* source, SKRect* dest, SKSamplingOptions sampling, SKPaint paint = null)
	{
	    if (image == null)
	    {
	        throw new ArgumentNullException("image");
	    }

	    SkiaApi.sk_canvas_draw_image_rect(Handle, image.Handle, source, dest, &sampling, paint?.Handle ?? IntPtr.Zero);
	}
...

Question

So, my question is that is SkiaSharp 3.0.0-preview2.1 on MAUI using Skia or Android Canvas for SKCanvasView and SKGLView? How should I read the code, in order to optimize our app?
