Hi,

I want to add a button to my Watchface for Gear 2. I will show battery status if the button is pressed.

Which function should I use for touch input event ? 

is it about Canvas api ?

canvas.addEventListener("touchstart", touchStartHandler, false);

Actually, I would like to search this in the Tizen Dev Guide, but there is no search option. And I couldn’t find a downloadable version of the guide.

Thanks.
