Hi!

Assume the below call from Android application's OnCreate( ) method: UrhoSurface.RunInActivity<MyApplication>(new ApplicationOptions("Data"));

Where MyApplication is defined following way:

internal class MyApplication : Urho.SimpleApplication
{
	public MyApplication(ApplicationOptions options) : base(options)
	{
		// init the app here
	}
}

The above causes following runtime exception:

Any idea why it doesn't work?

The documentation says:

The simplest way to run a game, as implemented in the MyGame class is to call

UrhoSurface.RunInActivity<MyGame>();

Maybe an override for Urho.Droid.UrhoSurface.RunInActivity with support for Urho.SimpleApplication is missing?
