I am trying to bind to a java class that inherits from the BaseColumn interface in Android and when I try to build, it gives me a build error that my class cannot have multiple base classes. Java.Lang.Object and Android.Provider.BaseColumns. When I look at the Android documentation, this is clearly defined as an interface:
but in Xamarin, it is defined as a public abstract class.
That is... an interesting overlook.
Quick explanation on the situation: Android.Provider.BaseColumn is not to represent that Java interface. It is there rather to define constants in that Java interface (because C# cannot define constants, we split out those constants into a class).
So there should be "IBaseColumn" interface. But since there is no member, our generator seems to think that it does not have to generate it.
We should fix this.
I have tried this issue and able to reproduce this issue at my end.
I am getting the same behavior describe in bug description.
