With this app, any device can get the heads-up notifications introduced in the new Android 5.0 “L Developer Preview”, no root required. But according to Addictivetips (and a lot of the users), this app "has done more than just replicate a feature of Android L. Even if you aren’t dying to try Android L and some of its new features, this app is worth a try".
