Compile error in java.exe, ListenableFuture is defined multiple times, with new Andriod App

[nlysaght]

I created a brand spanking new Xamarin Android App in Visual Studio 2022, I then referenced the v1.0.17.2 of the Xamarin.Stripe.Terminal.Android library. Compiled it without touching a line of code and I got the following issue Type com.google.common.util.concurrent.ListenableFuture is defined multiple times:

Just wondering if you would have any guidance on how to resolve this issue.

The full type error is here. Type com.google.common.util.concurrent.ListenableFuture is defined multiple times: C:\Users..me...nuget\packages\xamarin.google.guava.listenablefuture\1.0.0.2\buildTransitive\monoandroid50\guava-listenablefuture.jar:com/google/common/util/concurrent/ListenableFuture.class, obj\Debug\120\lp\54\jl\guava-28.1-android.jar:com/google/common/util/concurrent/ListenableFuture.class

You can see two jars referenced 1.0.0.2\buildTransitive\monoandroid50\guava-listenablefuture.jar obj\Debug\120\lp\54\jl\guava-28.1-android.jar

If I take the full java command line built by Visual Studio, and I then remove the reference the jar 1.0.0.2\buildTransitive\monoandroid50\guava-listenablefuture.jar then java compiles correctly com the command line, with a slew of warnings.

I'm just wondering if there is some way to exclude this JAR from the compile process in Visual Studio, so that the build can continue on correctly.

I actually have the 2.0+ bindings built. I just need to get the branch committed to master. It's built against Android 12 and should resolve some of your issues.

That would be great @chris-oswald , happy to make a contribution to the project if it would help, maybe purchase some professional services. I appreciate the time & effort that goes into these types of projects, I almost got the 2.5.2 branch working, but unfortunately just don't know enough about the Android side of things to get it over the line.

@nlysaght , I just submitted a PR on the 2.5.2 branch. You can look at the libraries I had to build for Android. I've also included my project references.
