Only first RuntimeIdentifier used in dotnet publish

[rgroenewoudt]

Android application type

Android for .NET (net6.0-android, etc.)

Affected platform version

VS2022 17.3.4

Description

I would like to set the runtime identifiers (x86/arm) when using the dotnet publish CLI.

dotnet publish -c Release -p:RuntimeIdentifiers="android-x86;android-arm" -p:AndroidPackageFormat=apk -o test
However this doesn't seem to work, only the first runtime identifier is used. The APK only contains libraries for x86 and not arm. The same problem happens when an a different runtime identifier is used such as android-arm64.

Steps to Reproduce

• Create a new Android .NET 6 app
• Execute dotnet publish -c Release -p:RuntimeIdentifiers="android-x86;android-arm" -p:AndroidPackageFormat=apk -o test
• APK only contains libraries for first runtime identifier and not the second.

Did you find any workaround?

No

@rgroenewoudt do you see some of the same issues with a .NET 6 console app? You can publish with win-x64 and win-x86, for example.

The reason I'm asking, is this might actually be an issue with the .NET SDK/CLI -- and not the Android workload.

I am not sure how to check this as far I know assemblies/exe cannot contain both 32-bit and 64-bit? Isn't Android a bit different that it can contain multiple?

Wat I did is create new .NET 6 console app and ran dotnet publish twice and used different orders for win-x86;win-x64. I used DotPeek to look at the assembly (project.dll, not exe) and only when win-x64 was first, then the DLL was a 64-bit version (dotPeek uses the IMAGE_FILE_HEADER in PE file format)

Current dotnet version is 6.0.401 (6.0.9)

Is there an workaround to specifically build an APK with x86 and one without x86?

I think the problem here is the dotnet CLI.

To workaround, you can put this in your project file:

<RuntimeIdentifiers Condition=" '$(No86)' == 'true' ">android-arm;android-arm64;android-x64</RuntimeIdentifiers>

And then pass -p:No86=true from the command-line. You can name No86 whatever you like, and add appropriate logic as needed?
