[Xamarin.AndroidX.Core 1.7.0.1] error : java.lang.RuntimeException: com.android.tools.r8.CompilationFailedException: Compilation failed to complete

[AigioL]

Version Information

• Visual Studio version : 17.1.3
• Xamarin.Android version : net6-android
• Using AndroidX :

<PackageVersion Include="Xamarin.AndroidX.Camera.Camera2" Version="1.0.2.2" />
<PackageVersion Include="Xamarin.AndroidX.Camera.Lifecycle" Version="1.0.2.2" />

Describe your Issue:

• See build logs
• I guess it was triggered by package Xamarin.Google.Guava.ListenableFuture > 1.0.0.4
• I found that downgrading the package to 1.0.2 fixes this bug

Steps to Reproduce (with link to sample solution if possible):

There was a bit of a mess trying to clean up the issues with ListenableFuture recently:

dotnet/maui#5305
dotnet/maui#5588

If you are using MAUI you may need to wait for the next preview.

If not, you might want to ensure all of your AndroidX packages are the latest, as these fixes were released within the last month.

I didn't use MAUI, and after trying multiple versions in the dependency package I found the problem was because Xamarin.AndroidX.Core 1.7.0.1

ReactiveUI.AndroidX 17.1.50 -> Xamarin.AndroidX.Core 1.7.0.1, causing the error

[jpobst]

Hmm, it is unfortunate that ReactiveUI.AndroidX is requiring a version of Xamarin.AndroidX.Core that has been delisted for being broken. (1.7.0.1)

However as luck would have it, we just released 1.7.0.2 today which you can try.

[AigioL]

I have just tested it and it can be fixed using this set of packages

<PackageReference Include="Xamarin.AndroidX.Camera.Camera2" Version="1.0.2.4" />
<PackageReference Include="Xamarin.AndroidX.Camera.Lifecycle" Version="1.0.2.4" />
<PackageReference Include="Xamarin.Google.Guava.ListenableFuture" Version="1.0.0.6" />
<PackageReference Include="ReactiveUI.AndroidX" Version="17.1.50" />
<PackageReference Include="Xamarin.AndroidX.Core" Version="1.7.0.2" />
<PackageReference Include="Xamarin.AndroidX.Legacy.Support.Core.UI" Version="1.0.0.14" />
<PackageReference Include="Xamarin.AndroidX.Lifecycle.LiveData" Version="2.4.1.1" />
<PackageReference Include="Xamarin.AndroidX.Preference" Version="1.2.0.1" />
<PackageReference Include="Xamarin.Google.Android.Material" Version="1.5.0.2" />

[jpobst]

Excellent, thanks for testing!
