Android L's Material Design principles explained by Google's Roman Nurik (video)
Android L comes with a brand new Material Design that is a huge evolution in the looks of Android and a step toward a more modern-looking design with simple, clutter-free visuals.
To better understand the new design and how new apps should be redesigned to fit in those new realities, the Android Developers channel has posted an explanatory video by Google engineer Roman Nurik. Nurik is best known for his DashClock widget and Muzei live wallpaper app.
To explain the Material Design principles in Android L, the engineer uses the Google I/O 2014 app. Every year, Google releases a new I/O companion app that is more than what it looks on the surface: it’s an illustration of all the design and coding principles that developers are advised to adopt. What drove the development of this year’s Google I/O 2014? Find out in the video below.
