Description

[severity:I’m unable to use this version]
Archiving apk using .net 7.0 for android with “Target platform” “ARM64” produces large apk that includes assemblies of other platforms “X86” and “x64” which increases apk size considerably.

Expected behavior is to only include assemblies of the selected target platform. For example if we select “ARM32” it should not include other platforms like “ARM64”, “X86” and “x64”.

Latest visual studio 2022 17.6.2

Steps to Reproduce

simple steps:

1. Create a maui project.
2. Right click the project to select the properties change Target platform to “ARM64” under Build->General
3. Build the project then archive apk.

To check it simply rename the apk as .zip file then open it and check folders “assemblies” and “bin” inside the apk. (please check attached screenshots)

The reproduction is not using .NET MAUI at all, while this probably would apply to .NET MAUI too, the core is in .NET for Android. Moving it to the right repo.

@mosammo: When you say "Archiving apk", are you referring to the Archive Manager within Visual Studio Tools > Archive Manager…?

Hi @jfversluis. We have added the "need-info" label to this issue, which indicates that we have an open question for you before we can take further action. This issue will be closed automatically in 7 days if we do not hear back from you by then - please feel free to re-open it if you come back to this issue after that time.

Archiving apk can be done in multiple ways:

• simplest option: right clicking the android project in "solution explorer" then click "Archive..."
• or use "Build" > "Archive..."
  After the apk is created simply rename the apk as .zip file then open it and check folders “assemblies” and “lib” inside the apk.

This option in VS seems to set:

<PlatformTarget>ARM64</PlatformTarget>

I think the first question is: is this the correct thing to set? I suspect we should be setting something like $(AndroidSupportedAbis) instead. @jonathanpeppers?

If so, then I think we need to give this to the UI team to set the correct property. I don't know how much they can change the "General" property pages in VS instead of the Android specific ones.
