Reflection Library – java.lang.Object

Hello,
I'm trying to use the Camera Zoom function. The code in the ACL does not work for me, so I thought I would try using the Reflection Library.

When I run the following code:
c1Refl.RunMethod2("setZoom", s, "java.lang.Object")

B4A always stops with an exception:
Java.Lang.NoSuchMethodException:setZoom [class java.lang.Object]

Am I doing something really dumb?

Thanks,
Barry.
