Conventions

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: "A folder target containing a chapter1.apk archive should be created."

A block of code is set as follows:

public class BookServiceImpl implements BookService {
  @Override
  public Book createBook(String title, String format, String color, Integer numberOfPages) {
    final Book book = new Book();
    book.setTitle(title);
    book.setFormat(format);
    book.setColor(color);
    book.setNumberOfPages(numberOfPages);
    return book;
  }
}

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

<dependency>
  <groupId>${project.groupId}</groupId>
  <artifactId>contract</artifactId>
  <version>1.0-SNAPSHOT</version>
  <type>pom</type>
</dependency>

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

$ANDROID_HOME//tools/android move avd --name Nexus_7_2012 --rename Nexus_7_2012_bis

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: "Clicking the Next button moves you to the next screen."

Note
