Implementation of a TextView and all its direct/indirect subclasses with native support for the Roboto fonts, including the brand-new Roboto Slab fonts. This library is compatible from API 14 (Android 4.0). To apply roboto typeface for original TextView (like a Calligraphy) you must attach inflater in your Activity class in the #onCreate() method. If you intend to use is not all fonts, the extra fonts can be removed.
