NativeAOT Android app crashes with UnsatisfiedLinkError using 10.0.103

[charlesroddie]

Android framework version

net10.0-android

Affected platform version

Workload 10.0.103

Description

Our Android app using NativeAOT crashes on startup when built with workload 10.0.103. The same app builds and runs correctly with workload 10.0.102. No code changes between the two builds.

Stacktrace:

Exception java.lang.UnsatisfiedLinkError:

I have only tested our app with this.
I haven't been able to try 11.0.100-preview.1 owing to an issue with the UseDotNet@2 task and preview sdks.

Steps to Reproduce

I have only tested our app with this.

Project configuration:

<Project Sdk="Microsoft.NET.Sdk">
	<PropertyGroup>
		<TargetFramework>net10.0-android</TargetFramework>
		<OutputType>Exe</OutputType>
		<RootNamespace>...</RootNamespace>
		<AssemblyName>...</AssemblyName>
		<SupportedOSPlatformVersion>26.0</SupportedOSPlatformVersion>
		<RuntimeIdentifiers>android-x64;android-arm64</RuntimeIdentifiers>
		<AndroidPackageFormats>aab</AndroidPackageFormats>
		<UseMauiEssentials>true</UseMauiEssentials>
		<InvariantGlobalization>true</InvariantGlobalization>
	</PropertyGroup>
	<PropertyGroup Condition=" '$(Configuration)' == 'Release' ">
		<PublishAot>true</PublishAot>
		<AndroidLinkTool>r8</AndroidLinkTool>
	</PropertyGroup>

Did you find any workaround?

Pin maui-android workload to 10.0.102

I don't see a commit related to NativeAOT in this range:

• 36.1.12...36.1.30

We did improve some things in main, @grendello is there a fix related to NativeAOT we should backport?

[grendello]

I would need to see the logcat output for this error first. @charlesroddie can you send us logcat output from around the crash? You can use these commands from the terminal:

$ adb logcat -G 16M
$ adb logcat -c
# Start the app here, wait ~10s, then:
$ adb logcat -d > logcat

Copilot found a change in dotnet/runtime that might cause it, does setting _UseNativeLibPrefix=true in the .csproj help any?

• [NativeAOT] Set _UseNativeLibPrefix=true to fix UnsatisfiedLinkError on Android #10825

[charlesroddie]

I got a good build with _UseNativeLibPrefix=true and 10.0.103 so that's very promising.
