DllNotFoundException on MAUI net8.0-android

[alexey-leonovich]

Magick.NET version

Magick.NET-Q8-AnyCPU 14.6.0

Environment (Operating system, version and so on)

Windows 10 x64 22H2 + Android Emulator (default virtual device - Pixel 7 API 35) + VS 2022 17.13.5

Description

I've created a netstandard20 class library and added Magick.NET-Q8-AnyCPU 14.6.0 nuget reference to it. In it I simply open image via:
using var image = new MagickImage(new FileInfo(imagePath));
And I've created MAUI application from a template (.NET 8.0 framework), referenced my class library and called that method. And i got an exception:

{System.TypeInitializationException: The type initializer for 'NativeMagickSettings' threw an exception.

Running same MAUI application on Windows (net8.0-windows10.0.19041.0 target) is ok. Looks like it's Android specific.

Steps to Reproduce

1. Create a netstandard20 class library
2. Add Magick.NET-Q8-AnyCPU 14.6.0 nuget reference
3. Create Graphics.cs with Graphics class and TestMagick function that calls using var image = new MagickImage(new FileInfo(imagePath));
4. Create MAUI application (chose .NET8.0 framework)
5. Refefence the class library in the MAUI application
6. Add a call of Graphics.TestMagick function
7. Start debugging on Android Emulator (default virtual device - Pixel 7 API 35)

As mentioned in #22 there is no support for running this library on android.

[alexey-leonovich]

Is that because there is no official build of native Magick library for this OS? There is an unofficial Android build which is synced to main repo.

[dlemstra]

That is not a build of the Magick.Native library but a custom build of ImageMagick.

[alexey-leonovich]

I got you point. Just curious: there is a technical limitation to make an Android version of the Magick.Native library or it's just a lack of time?

[dlemstra]

Maybe both? I haven't invested any time in making the build work on android or ios.
