Does this mean the native handler works for some cases? And what if the native handler improves in the future to have better support? Should there be a switch to ignore this check and allow using the native handler?

My thought is if that happens, the grpc-dotnet client can be updated to detect the Android OS version that fully supports gRPC, and not throw this error.

Android uses a native HTTP handler if
HttpClientHandleris specified. The native HTTP handler doesn't have enough HTTP/2 support for gRPC and can cause errors. Example: #1923. We want Android to always useSocketsHttpHandler.Detect if a native HttpHandler is being used on Android, and throw a friendly error message on Android if necessary.
Doc at https://aka.ms/aspnet/grpc/android will be added soon.
