Android rockt: Immer mehr Android-Geräte der unterschiedlichsten Formen und Größen kommen auf den Markt. Das bedeutet für Entwickler natürlich einerseits einen wachsenden Markt. Andererseits bedeuten mehr Gerätetypen auch mehr zu berücksichtigende Unterschiede im Code. Dieser Fragmentierung können Sie begegnen, indem Sie Ihre Apps mit Standard-Webtechnologien erstellen.

Annotation. If you know HTML, CSS, and JavaScript, you already have the tools you need to develop Android apps. With this book, you'll learn how to use these web technologies to design and build apps for any Android device, using the framework of your choice.

If you know HTML, CSS, and JavaScript, you already have the tools you need to develop Android applications. Now updated for HTML5, the second edition of this hands-on guide shows you how to use open source web standards to design and build apps that can be adapted for any Android device. You’ll learn how to create an Android-friendly web app on the platform of your choice, and then use Adobe’s free PhoneGap framework to convert it to a native Android app. Discover why device-agnostic mobile apps are the wave of the future, and start building apps that offer greater flexibility and a much broader reach. Convert a website into a web application, complete with progress indicators and other features Add animation with JQTouch to make your web app look and feel like a native Android app Make use of client-side data storage with apps that run when the Android device is offline Use PhoneGap to hook into advanced Android features, including the accelerometer, geolocation, and alerts Test and debug your app on the Web with real users, and submit the finished product to the Android Market

Es geht auch ohne Objective-C und Cocoa! Wenn Sie HTML, CSS und JavaScript konnen, haben Sie alles, was Sie brauchen, um eine schicke, funktionstuchtige iPhone-Applikation zu entwickeln. Im iPhone-Look&Feel, nur mit Standard-Technologien und unschlagbar einfach. Wer will schon gern bei Null anfangen? Sich in eine neue Programmiersprache und ungewohnte Entwicklungswerkzeuge einzuarbeiten, ist ganz schon muhsam und vollig uberflussig. Nutzen Sie Ihr Webwissen und legen Sie los: Mit HTML5 konnen Sie Daten auf dem Client speichern und Anwendungen entwickeln, die offline funktionieren. Mit CSS bekommen Sie den echten iPhone-Look hin, und mit den richtigen JavaScript-Helfern klappt s auch mit den Animationen. Das Beste aus zwei Welten Wollen Sie den App Store als Verbreitungskanal fur Ihre Anwendung nutzen? Oder mochten Sie, dass Ihre App auf verschiedenen mobilen Geraten lauft? Dann nutzen Sie das Open Source-Framework PhoneGap, das aus Ihrer Web-App ein installierbares Programm macht. Die Vorzuge der Webversion konnen Sie trotzdem nutzen: Testen und verbessern Sie Ihre App kontinuierlich und zeitnah, bevor Sie sie Apples Review-Prozedere uberantworten. Kompakt, schnell, praxisbezogen Jonathan Stark ist kein Freund des Seitenschindens: Er kommt sofort zur Sache und bringt alle in der Praxis wichtigen Schritte klar und strukturiert auf den Punkt. Vermutlich brauchen Sie fur diesen kompakten, praxisnahen Leitfaden nur wenige Stunden, und Ihre Anwendung steht."
