In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

[Activity(
  Label = "My App",
  MainLauncher = true,
  Icon = "@drawable/icon")]
public class MainActivity : Activity
{
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <string name="buttonText">Hello World!</string>
</resources>

Any command-line input or output is written as follows:

adb shell bmgr backup <android-package-name>
adb shell bmgr run
adb shell bmgr restore <android-package-name>

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Click on the Download Xamarin for Windows or Download Xamarin for OS X links, depending on the operating system you are using."
