Palm Webos

A Note from the Author and from O'Reilly Media about what this bookdoes--and doesn't--do: Palm webOS is a brand new platform and represents a very different type ofoperating system where the web runtime is used as the basis for the UI andApplication model. Palm and O'Reilly felt that it was important to have abook available to help developers get a basic understanding of the new Palmplatform at the time that the SDK was released; this timing played a majorrole in the content and structure of the book. Ideally this book would have been a complete reference of the new platformbut that wasn't possible since the content was written at the same time asthe software SDK was being developed by the Palm engineering team. The bookdoes provide a complete overview of Palm webOS, a thorough description ofthe application model and gives details on many key design concepts. Thereare descriptions and examples of UI widgets, services, storage,notifications, dashboards and background applications, serving as a greatintroduction but not as a definitive source. The book uses a simple News reader application to illustrate the technicaldescriptions but the examples are not intended to serve as a cookbooktutorial. Experienced developers should be able to use the examples to buildup a working application chapter by chapter but others may not find theloose descriptions adequate for recreating the application unaided. Overtime, these different needs will be filled by other books, but in themeantime we hope that this book will serve a valuable role introducingdevelopers to webOS and giving them a way of getting started with webOSapplication development. A second printing of the book will update any original coverage obsoleted bysubsequent Mojo SDK builds. For owners of the original printing of the book,all of these updates are posted on the "View/Submit Errata" link (please seeleft-hand column of this web page). Thanks for understanding that book publishing and coverage of rapidly movingtechnologies can sometimes be an inexact science; we knew there'd be a needfor a book such as Palm webOS: The Insider's Guide to DevelopingApplications in JavaScript using the Palm MojoT Framework, and there'scertainly no better person to write that book that Mitch Allen; that said,we understand that because it is such a new operating system and SDK, therewould (and will continue to be) changes that at best can't be documented andexplored until new printings of the books are released. In the meantime wewill be diligent in posting updates to this book's O'Reilly Media catalogpage.

You'll also learn how to extend existing web apps to work with the new generation of mobile phones. Get a thorough overview of the webOS platform and architecture Understand the critical concepts for application design: what separates webOS from other web and mobile platforms Learn the details of Mojo's development tools and SDK for building and testing mobile applications Examine best practices, important considerations, and guiding principles for developing with webOS and the Mojo framework

PhoneGap is a standards-based, open-source development framework that can be deployed to any mobile device without losing the features of the native app—allowing for access to device contacts, the local file system, camera, and media on multiple platforms without requiring users to write a single line of code. Ideal for intermediate to advanced users, PhoneGap Build: Developing Cross Platform Mobile Applications in the Cloud offers the comprehensive coverage you need to harness the power of this dynamic tool. It provides complete coverage of the cloud computing platform and the theories behind cloud computing, using a series of engaging examples. The book explains the differences between existing mobile platforms, the different types of browsers they support, and the programming languages and integrated development environment required to develop apps for each of them. It then describes how PhoneGap makes the task of developing cross-platform mobile apps easier. This book will teach you how to use: HTML5, CSS3, and JavaScript to develop apps for devices across various mobile operating systems PhoneGap Build to develop mobile apps in the cloud PhoneGap with Sencha Touch and jQuery Mobile Back end databases to store and retrieve information The text starts with simpler applications and gradually moves toward describing advanced concepts and how to exploit different application programming interfaces and methods. By the time you finish the book, you will learn how to develop feature-rich mobile applications that can run on the cloud to support different platforms. Supplying authoritative guidance and proven best practices for designing cloud-based applications, the book is an ideal reference for cloud system developers, architects, and IT professionals. It is also suitable for use in instructional settings.

Today's market for mobile apps goes beyond the iPhone to include BlackBerry, Nokia, Windows Phone, and smartphones powered by Android, webOS, and other platforms.

You'll learn the particulars and pitfalls of building mobile apps with HTML, CSS, and other standard web tools. You'll also explore platform variations, finicky mobile browsers, Ajax design patterns for mobile, and much more. Before you know it, you'll be able to create mashups using Web 2.0 APIs in apps for the App Store, App World, OVI Store, Android Market, and other online retailers. Learn how to use your existing web skills to move into mobile development Discover key differences in mobile app design and navigation, including touch devices Use HTML, CSS, JavaScript, and Ajax to create effective user interfaces in the mobile environment Learn about technologies such as HTML5, XHTML MP, and WebKit extensions Understand variations of platforms such as Symbian, BlackBerry, webOS, Bada, Android, and iOS for iPhone and iPad Bypass the browser to create offline apps and widgets using web technologies

This book demonstrates the usefulness of the modern smartphone for providing location aware applications to the tourist as an end user. During the course of this book it has been demonstrated that the modern smartphone has the accuracy and responsiveness required to provide excellent location aware functionality to the tourist end user. The GPS section outlines how a developer can leverage this functionality to make apps that use close quarter location positioning to help the average tourist in a host of different ways. It has also been demonstrated that bluetooth and other technologies such as QR coding are effective at providing location aware functionality in situations where GNSS(GPS) is ineffective, such as in indoor environments. Lastly, the book outlines how an engineer could provide augmented location services when GPS is not available by using the RSSI signal from Bluetooth devices.

The miniature web applications known as gadgets (or widgets) are a key component of the distributed web and an ideal way to publish your content far beyond the reach of your own web site. Packaging web content and functionality into a gadget enables it to be seen anywhere from iGoogle to the iPhone—wherever the user may be, on or off the traditional web. Everyone can access your content without having to visit your web site. This book is a practical guide to building gadgets that will work everywhere, from handheld devices to any site on the web. The core methodology is to develop a single code base that will run on all platforms, multiplying the syndication opportunities for maximum return on your development investment. Extending this approach is a technique of abstracting key API calls from the various gadget platforms into a single interface layer, implemented in the book as a compact JavaScript class, allowing your gadgets full access to every platform's power without your having to rewrite your code for each. Learn the key concepts for successfully syndicating web content via gadgets. Build platform-agnostic gadgets that run on all the major web portals. Deploy your gadgets to web-enabled handheld devices.

The goal of this ebook is to introduce you to mobile Web development. In many ways it is very similar to desktop Web site development - HTML5 is HTML5 no matter what device you install it on.What is different is how you use and interface with the device. Smartphones and tablets like the iPad, iPhone, and android devices are just very different than laptops and desktops. Find out how to work within mobile versions of popular web browsers while maximizing your design with HTML5 and CSS3 basics. Discover how to place items, work with fonts, and control color detail as well as other critical yet simple design elements. Work on graphical control with Bitmap, SVG and Canvas elements
