Disable finger touch with Samsung Pen SDK

Hi, 

I’m working on an android project. 

I just tried corona enterprise couple of week, I have a question, how to disable finger touch, I tried once but without corona sdk with (SpenSurfaceView.TOOL_FINGER, SpenSurfaceView.ACTION_NONE); 

how to call the command to be used in the lua language, in the corona project? 

does anyone have the same problem or can handle? 

thanks
