I'm not sure it'll solve the issue but it doesn't look like you have applied this detail from the docs: https://learn.microsoft.com/en-us/dotnet/communitytoolkit/maui/views/mediaelement?tabs=android#platform-specific-initialization

@bijington

I applied this detail and I got this VS Issue. So I rebooted windows and started it again. It took several minutes for VS to start the clean/build but it eventually ran.

I continued to get this error.

From your report, I don't think the issue is with this repo... Following your log I could find that Xamarin.Google.Guava has a dependency on Xamarin.Google.Guava.ListenableFuture, but the dependency requires a version greater than 999, which doesn't exist on nuget, so looks like the Xamarin.Android team is using a local package reference instead of the nuget feed.

cc: @moljac @jonathanpeppers.

[jpobst]

Version 9999.0.0 does exist on NuGet, it is just unlisted so it doesn't show up in searches:
https://www.nuget.org/packages/Xamarin.Google.Guava.ListenableFuture/9999.0.0

If I recall, the reason is that Guava and Guava.ListenableFuture both contain com.google.common.util.concurrent.ListenableFuture so if you reference them both you get a duplicate Java class.

Thus if you reference Guava we demand the 9999.0.0 dummy package that is empty, so only the ListenableFuture from Guava is pulled in.

In short, you do not want to reference both Guava and a specific version of Guava.ListenableFuture.

I'm not sure what changed, but it no longer occurs.
