#javaModule can call functions and pass parameters to the class defined in the Java Module I defined.

so now I want to send data back from the java side of the wall into GDScript.
The documentation says to use this function declaration

GodotLib.calldeferred(<instanceid>, "<function>", new Object[]{param1,param2,etc})

I have the instance id, I define a function and set some parameters,
ex: GodotLib.calldeferred(m_device_id, "this_is_a_test", new Object[]{31, "thirty one", (float)31,(boolean)true, "False"});

I can see something is happening because in the adb logcat displays this,

I/godot   ( 8513): ARGNAME: java.lang.Integer
I/godot   ( 8513): ARGNAME: java.lang.String
I/godot   ( 8513): ARGNAME: java.lang.Float
I/godot   ( 8513): ARGNAME: java.lang.Boolean
I/godot   ( 8513): ARGNAME: java.lang.String

Those match the function that I setup but in GDScript I can't just do

bbAdmob.do_something_in_java()
#java code gets done

How do I run this:GodotLib.calldeferred(<instanceid>, "<function>", new Object[]{param1,param2,etc})
to get these params back to GDScript
