FaceAware Imageview

I am looking for face Aware Image-view. Instead of cropping Image or simply center crop scale type of Imageview, the face should detect in image-view and adjust face to center of Image-view. As your library crop the picture i want to do it without cropping picture.

I got Library in IOS but not getting anything in Android. https://github.com/BeauNouvelle/FaceAware

The second scenario what does this library do if image have 3 faces? Can anyone help me out? Thank You.
