[Mobile] C# Nuget for Android

[GuiOliv]

I am writting an app using MAUI Blazor and I'm trying to load a mocal locally on my phone. However, everytime it hits the line var model = new Model(modelPath);, it throws the exception System.DllNotFoundException "onnxruntime-genai".

I have tried copying dll files multiple times, using them, installing the package on multiple projects but nothing worked.

To reproduce
To reproduce, you may try to load a local model by copying it to your phone and using

   string modelPath = "/storage/emulated/0/onnx/cpu_and_mobile/cpu-int4-rtn-block-32";

Then simply load the model with the line var model = new Model(modelPath);, all this while debugging with your phone via USB.

Visual Studio Community Version 17.10.0

This is a personal project so not of much urgency but I would really appreciate if I could have any help.

Does it tell you which DLL it can't find?

I'm guessing you will need a different backend NuGet package for Android, but I'm not sure which one. I do see that Microsoft.ML.OnnxRuntime.Managed has some Android and iOS targets though...

We do not have a nuget package that supports Android yet.

Having said that, we recently added Java bindings and support for building for android.

Would that work for you? We can consider adding nuget support for Android in the near future.

Considering I am using C#, it wouldn't be really helpful.

Would love to see nuget support for Android tho.

Thank you for your answer @baijumeswani

Has this been even fixed? Whats the point in closing the original issue and conversion to a discussion?

@ggt-k The PR related is pending review: #923 Hopefully we can have Android NuGet support in the next release.
