   @sbomer I tried these suggestions in 5aa7cee.

   I'm getting some warnings when using TrimmerDefaultAction=link:

   packages\microsoft.android.runtime.android-arm64\11.0.200-ci.main.232\runtimes\android-arm64\lib\net6.0\Java.Interop.dll warning IL2104: Assembly 'Java.Interop' produced trim warnings. For more information see https://aka.ms/dotnet-illink/libraries 
   packages\microsoft.android.runtime.android-arm64\11.0.200-ci.main.232\runtimes\android-arm64\lib\net6.0\Mono.Android.dll warning IL2104: Assembly 'Mono.Android' produced trim warnings. For more information see https://aka.ms/dotnet-illink/libraries
   

   But I don't see exactly what the issues are? I think we probably want to fix them.

   @jonathanpeppers try setting <TrimmerSingleWarn>false</TrimmerSingleWarn> to get the detailed warnings (there might be more than a few depending on what the problem is).
