Android library compiling issues due to uno out of date lib requirements

[mitchcapper]

You might need to add some extended instructions for uno. Unfortunately it currently pulls an older version than what the ML library requires and it seemed best was fixing the specific version uno requires. Sadly this has a hardcoded version number, for current:
Adding this to the solution got it working:

<propertygroup>
    <!--
  Plugin.Scanner.Uno pulls in MLKit, which requires newer AndroidX than the Uno SDK's
  implicit defaults (NU1605 package downgrade). These properties override the versions
  the Uno SDK injects for its implicit AndroidX PackageReferences.
-->
    <AndroidXActivityVersion>1.12.2.1</AndroidXActivityVersion>
    <AndroidXAppCompatVersion>1.7.1.2</AndroidXAppCompatVersion>
</propertygroup>
    <ItemGroup Condition="$(TargetFramework.Contains('-android'))">
        <!--
          androidx compose runtime-annotation ships as a KMP library: the .Android (aar) and .Jvm (jar)
          variants both define androidx.compose.runtime.* and both land in the graph, so D8 fails with
          "Type androidx.compose.runtime.Stable is defined multiple times". Gradle picks one variant;
 so drop the JVM one - .Android has the same types.
        -->
        <PackageReference Include="Xamarin.AndroidX.Compose.Runtime.Annotation.Jvm" ExcludeAssets="all" />
    </ItemGroup>

What instructions do you have in mind? This is a general issue when working with android packages which can't be fixed by plugins.

Normally its a bit more straightforward but because uno tries to make it 'easy' they do a decent bit of magic to auto add all the packages behind the scenes.

I initially tried to manually override the package versions but you can't just select another version with it part of the sdk:

The official docs mention you can disable all implicit packages but that quite a few packages you then must install yourself.

The AndroidXActivityVersion/AndroidXAppCompatVersion took me a bit to find as they don't cover it on https://platform.uno/docs/articles/features/using-the-uno-sdk.html?tabs=uno-packages .

Not specific to this app, but as the latest uno will cause this to occur with the latest version here something along the lines of:

If you are unable to add this package to your project due to NU1605 ("Detected package downgrade") you may need to manually force uno to use a more modern version of the conflicting packages to meet the current android minimums for ML.
This can most easily be done in the project file by adding a to a property group like so:

    <AndroidXActivityVersion>1.12.2.1</AndroidXActivityVersion>
    <AndroidXAppCompatVersion>1.7.1.2</AndroidXAppCompatVersion>
