This makes the minimum supported Android version 4.1, API level 16.
It drops use of the Android support-v4 fragment. The v4 and v13 support libraries are used only to support PagerAdapter, which remains a helpful utils function from these support libraries. They use the native Fragment classes, meaning we're off of android.support.v4.app.Fragment and its supporting classes altogether.
