This says in limitations: "Android callable wrappers are needed any time the Android runtime needs to invoke managed code. Android callable wrappers are generated at compile time by the monodroid.exe tool, based on static analysis of IL. The net result of this: you cannot use dynamic languages (IronPython, IronRuby, etc.) in any scenario where subclassing of Java types is required (including indirect subclassing), as there's no way of extracting these dynamic types at compile time to generate the necessary Android callable wrappers."
