Info

INTRODUCTION Chapter 2 outlines these requirements in more detail and describes where to download and how to install each component. CONVENTIONS To help you get the most from the text and keep track of what’s happening, we’ve used a number of conventions throughout the book. The pencil icon indicates notes, tips, hints, tricks, and asides to the current discussion. Boxes with a warning icon like this one hold important, not-to-be forgotten information that is directly relevant to the surrounding text. As for styles in the text: ‰ We show file names, URLs, and code within the text like so: persistence.properties. ‰ To help readability, class names in text are often represented using a regular font but capitalized like so: Content Provider. ‰ We present code in two different ways: We use a monofont type with no highlighting for most code examples. We use bold to emphasize code that is particularly important in the present context or to show changes from a previous code snippet. ‰ In some code samples, you’ll see lines marked as follows: [ ... previous code goes here ... ] or [ ... implement something here ... ] These represent instructions to replace the entire line (including the square brackets) with actual code, either from a previous code snippet (in the former case) or with your own implementation (in the latter). ‰ To keep the code samples reasonably concise, I have not always included every import statement required in the code samples. The downloadable code samples described below include all the required import statements. Additionally, if you are developing using Eclipse, you can use the keyboard shortcut Ctrl+Shift+O (Cmd+Shift+O) to insert the required import statements automatically. xl
INTRODUCTION SOURCE CODE As you work through the examples in this book, you may choose either to type in all the code manually, or to use the source code files that accompany the book. All the source code used in this book is available for download at www.wrox.com. When at the site, simply locate the book’s title (use the Search box or one of the title lists) and click the Download Code link on the book’s detail page to obtain all the source code for the book. Code that is included on the web site is highlighted by the following icon: Listings include the filename in the title. If it is just a code snippet, you’ll find the filename in a code note such as this: code snippet filename Because many books have similar titles, you may find it easiest to search by ISBN; this book’s ISBN is 978-1-118-10227-5. Once you download the code, just decompress it with your favorite compression tool. Alternately, you can go to the mai n Wrox code download page at www.wrox.com/dynamic/books/download .aspx to see the code available for this book and all other Wrox books. ERRATA We make every effort to ensure that there are no errors in the text or in the code. However, no one is perfect, and mistakes do occur. If you find an error in one of our books, like a spelling mistake or faulty piece of code, we would be very grateful for your feedback. By sending in errata, you may save another reader hours of frustration, and at the same time, you will be helping us provide even higher quality information. To find the errata page for this book, go to www.wrox.com and locate the title using the Search box or one of the title lists. Then, on the book details page, click the Book Errata link. On this page, you can view all errata that has been submitted for this book and posted by Wrox editors. A complete book list, including links to each book’s errata, is also available at www.wrox.com/misc-pages/ booklist.shtml. xli
