Thanks for the feedback

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

net6.0-android is out of support and you will not get the newest package versions.

I just installed the latest nuget packages and now I get the below build issue.

Please, provide list of packages

I couldn't even install these - I get a version conflict error.

These packages are a bit of a disaster...

Thank you very much @wartedmars for the recommendation. I was getting the same LiveDataKt$observe$wrappedObserver$1.class error building net8.0-android app after updating to the latest nugets. This seemed to quell the issue.

The last few times I've updated these packages it has caused build errors and forced me to add or remove packages. 😑

For reference:

I was missing 

<PackageReference Include="Xamarin.AndroidX.Legacy.Support.V4">
      <Version>1.0.0.28</Version>
</PackageReference>
<PackageReference Include="Xamarin.AndroidX.Lifecycle.LiveData">
      <Version>2.8.4.1</Version>
</PackageReference>

Now I have

<!-- Relevent app packages -->
<PackageReference Include="Xamarin.Build.Download" Version="0.11.4" />

<!-- Android specific packages -->
<PackageReference Include="Xamarin.AndroidX.Activity">
    <Version>1.9.1.1</Version>
</PackageReference>
<PackageReference Include="Xamarin.AndroidX.Activity.Ktx">
    <Version>1.9.1.1</Version>
</PackageReference>
<PackageReference Include="Xamarin.AndroidX.Collection">
    <Version>1.4.2.1</Version>
</PackageReference>
<PackageReference Include="Xamarin.AndroidX.Collection.Ktx">
    <Version>1.4.2.1</Version>
</PackageReference>
<PackageReference Include="Xamarin.AndroidX.Legacy.Support.V4">
    <Version>1.0.0.28</Version>
</PackageReference>
<PackageReference Include="Xamarin.AndroidX.Lifecycle.LiveData">
    <Version>2.8.4.1</Version>
</PackageReference>
<PackageReference Include="Xamarin.Firebase.Messaging">
    <Version>124.0.0.1</Version>
</PackageReference>
<PackageReference Include="Xamarin.Google.Dagger">
    <Version>2.52.0</Version>
</PackageReference>
<PackageReference Include="Xamarin.GooglePlayServices.Base">
    <Version>118.5.0.1</Version>
</PackageReference>

I had similar problem but different package. I solved it by updating "problematic" transient package version to the latest. After that other package version was causing the problem and I updated it as well, and so on. I was persistent and after several updates everything worked fine. I also updated "Microsoft.Maui.Controls" and etc.

In your case update "Xamarin.AndroidX.Lifecycle.LiveData.Core" package to the latest. After that probably some other package will throw exception. Find it in transient packages and update it too, and so on till project starts.

Adding these 3 packages for Android solved this issue for me.

<ItemGroup Condition="'$(TargetFramework)' == 'net8.0-android'">
    <PackageReference Include="Xamarin.AndroidX.Lifecycle.LiveData.Core" Version="2.8.4.1"/>
    <PackageReference Include="Xamarin.AndroidX.Lifecycle.LiveData" Version="2.8.4.1"/>
    <PackageReference Include="Xamarin.AndroidX.Lifecycle.Common" Version="2.8.4.1"/>
</ItemGroup>
