CSS3 Animation is delayed on Android Webview

ionic-v1
1

I’ve got this code to trigger the animation:

$ionicGesture.on('dragstart', function(event) {
	ionic.requestAnimationFrame(function() {
		//do something
	});
}, elem);

I’ve got the element animating by following SCSS:

@include transition($transition-time ease-in-out);
@include transition-property(transform);
@include transform(translate3d($x, $y, 0));

It’s work perfectly on ios7. However, i got a noticeable delay before the element animating on Android Webview.
Any idea to fix this?

Many thanks,

What version of android are you testing this on?

Currently on Samsung S4 Android 4.4.2. I think i’ve found the reason now.
I tried to bind ‘touchstart’ & ‘touchend’ event and the delay has gone.

In my test, ‘touchstart’ is fired 170ms earlier than ‘dragstart’.
