# Android Lollipop Exercise

Android app to use as the base app for implementing the following material widgets and animations that were introduced in Android 5.0 (API level 21).

* RecyclerView (the new ListView)
* CardView (custom outline and shadow)
* Ripple animation (touch feedback)
* Palette (Incorporate dynamic color)
* Shared Element Activity Transition
* Floating Action Button

Once a contact is selected from the list, a second screen appears with additional details about the contact, including his contact no. and a floating action button to place a phone call to this contact.
