How to crop image in android as well as ios?

Alas, I cannot get ngImgCrop to work. I am loading an image from the camera roll and the loaded image appears as it should with the cropping tool, but when I drag, resize, etc and mouseup, Cropped image does not appear. iOS simulator 9.1. If someone has had better luck and has a working example to share, please do.

you can see my fork of jr-crop, i have added rotate button on it.
