Please try with extending Adapter if you're not doing that. I don't know how the UIImagePickerController works but you should be able to get hold of the root ViewController and somehow push your UIImagePickerControllerDelegate. Something like UIApplication.getSharedApplication().getKeyWIndow() should get you the UIWindow created by JavaFX and then you can use the rootViewController property to change what gets displayed.
