Is it possible to add a HTML5 canvas element as a field to the android app ?


The title probably says it all. I want to create a canvas field on the app where users can draw their signature! I am aware that will have to create the canvas and the logic of it myself!
but how can I show it on the android app ?
it works actually fine on the desktop version.

Alternatively, is there a way to show an iframe field on the app as well ?!
