Seems like they "ported" lollipop animation in pre-L devices. The simplest way to do this is using libraries like Igvalle's Material-Animation (see #4). Its minSdk is 16, but I hope you can decrease it for 14 or below.

Some other libraries: TransitionsBackport, PreLollipopTransition, transitions-everywhere.

Please let me know if you create this animation!
