Is there a way to have a kind of facetime between an iphone 4 and Sony Xperia?

Skype.

Facetime is an Apple/iOS only app

Sony Xperia is Andriod

No, Facetime is a feature only iphones have.

FaceTime works only on Apple devices.

The closest thing on a non-Apple phone would be Skype or Viber, but they aren't as easy to use as FaceTime.
