This update:

Adds more to the Android P coverage, including:

A dedicated chapter on publising slices

BiometricPrompt (as the replacement for FingerprintDialog, which itself
replaces the now-deprecated FingerprintManager)

AppComponentFactory

WebView tracing

New salvos in ���the War on Background Processing���

Updates much of the book to cover Android Studio 3.1

Added material on the 1.1 release of ConstraintLayout, including groups, barriers,
percentage constraints, and circular constraints

Rewrote the fragments chapter to focus on the fragments backport

Updated most remaining samples to use the fragments backport, for those that
were not doing so already

Converted some samples that were using ListView to use RecyclerView, and
moved the RecyclerView chapter to be earlier in the book

Added some material on the Chrome OS emulator

Moved the material on SlidingPaneLayout to the Widget Catalog

Made minor improvements to the chapters on Espresso, unit testing, and Ui Automator

Retired the chapter on dynamic code, the chapter on Android Things, the
chapter on SlidingDrawer (from the Widget Catalog),
and the chapter on large screen strategies,
as well as some other specific sample apps and their corresponding sections)

Fixes a variety of errata and other miscellaneous bugs

Right now, I expect that I will publish Version 8.13 in about two months.
