4.2-dev4 C# export to Android generates the APK fine, but fails finding .NET assemblies for arm64 at runtime

[Oyama-Oyama]

Godot version

4.2 dev 4

System information

mac 12.6.7

Issue description

Why is this? What can I do to fix it?

Steps to reproduce

I assume you're actually testing 4.2 dev 4? 4.1 doesn't support Android for C# exports.

Sorry, it's actually 4.2 dev 4

Your MRP doesn't contain a C# project.

[akien-mga]

Your MRP doesn't contain a C# project.

So it might be the old issue where exporting a non-C# project with a .NET enabled build still tries to initialize .NET but doesn't copy the libraries?

The same thing here, i cant build the project:

C:\Users\AORUS\Documents\MyRPGGodot\MyRPG-Godot.csproj : error NU1102: Unable to find package Microsoft.NETCore.App.Runtime.linux-bionic-arm64 with version (= 6.0.18)

C:\Users\AORUS\Documents\MyRPGGodot\MyRPG-Godot.csproj : error NU1102: - Found 0 version(s) in Microsoft Visual Studio Offline Packages

And i cant install the nuget either cause it's not compatible with the project.
OS: WINDOWS 11

Justing to give more information:
I'm using godot 4.2.dev4-mono
.net7.0 as recommended

I can't build any architectures of android apk

So it might be the old issue where exporting a non-C# project with a .NET enabled build still tries to initialize .NET but doesn't copy the libraries?

I slightly remember something like that but I can't find the issue now, I don't remember if it was resolved. It shouldn't copy any .NET libraries if there is no C# project, but then the exported project shouldn't attempt to load them, otherwise you can't export GDScript-only projects from the .NET version (this will become more important with Editor unification, maybe #74089 already solves this).

@arnilsenarthur You have to target .NET 7.0. Change <TargetFramework>net6.0</TargetFramework> in the .csproj file to <TargetFramework>net7.0</TargetFramework> and make sure you have the 7.0 SDK installed. Also, I believe only arm64 works at the moment.

[arnilsenarthur]

I already did this and still not worked.
after i added <UseMonoRuntime>true</UseMonoRuntime> it worked, but the app opens, then turn black and crashes.
tested on android device emulator and on a real device

[arnilsenarthur]

Yep, i give up by now. I created a empty project in a non-mono godot version then it installed and worked with no problems. but even an empty mono android project does not work

[rekliner]

Same experience here with the unmodified XR Tools demo and 4.2dev4. Loads ok non-mono. As you suspected @raulsntos I had not added any C# code yet.

[arnilsenarthur]

Using android studio log i tried to understand what's wrong and seems something about vulkan, but i'm not sure.
I asked at discord if it's viable to use C# in a project aiming to launch it to mobile/desktop by december or should I just use gdscript, even when if i need to rewrote some code, I'll wait for the answer and halt my production for a while. But anyway if you need more info about the issue just ask and I'll send it here

I'm seeing the same error in my project. I'm using the PlayFab C# SDK. It seems to happen on a call to that library.
