kineticjs tween on android left the original image

Question

I'm using KineticJs to develop a webapp, but i found that when i'm using tween() on android, it always left a original image when the tween starts. And it's also happens on the Kineticjs tutorials page with my galaxy note2. is it a bug?

here is my screen shot...

Answer 1

This is an android canvas bug.

One of tips - draw on canvas after small delay:

var stage = new Kinetic.Stage(conf);
var layer = new Kinetic.Layer();

stage.add(layer);

setTimeout(function(){
    // add shapes to the layer and then do layer.draw()
}, 300);
