Spen palm rejection

Hi !

I have an Android app for free drawing.
Because Spen SDK is deprecated, I developed with HTML Canvas.
But I have a problem.
When I drawing a picture with my Spen on my hand(palm) touched at tablet screen, the drawing is maked a line from my hand to my Spen.
Is there any API(Samsung or Android or Web Browser) or method to prohibit hand touch when using Spen? (like Apple Palm rejection API)
