The Android development platform, created by Google and the Open Handset Alliance, is a platform in its truest sense, encompassing hundreds of classes beyond the traditional Java classes and open source components that ship with the SDK. With Beginning Android 2, you’ll learn how to develop applications for Android 2.x mobile devices, using simple examples that are ready to run with your copy of the SDK. Author, Android columnist, writer, developer, and community advocate Mark L. Murphy will show you what you need to know to get started programming Android applications, including how to craft GUIs, use GPS, and access web services.
What you’ll learn
Discover Android and how to use it to build Java-based mobile applications for a wide range of phones and other devices.Create user interfaces using both the Android widget framework and the built-in WebKit-powered Web browser components. Utilize the distinctive capabilities of the Android engine, including location tracking, maps, and Internet access. Use and create Android applications incorporating activities, services, content providers, and broadcast receivers. Support Android 1.5, 1.6, and 2.0 devices, including dealing with multiple Android OS versions, multiple screen sizes, and other device-specific characteristics.
Who is this book for?
This book is aimed at people new to mobile development, perhaps even to Java development itself. On the plus side, Android-style smartphones are sexy. Offering Internet services over mobile devices dates back to the mid-1990s and the Handheld Device Markup Language (HDML). However, only in recent years have phones capable of Internet access taken off. Now, thanks to trends like text messaging and products like Apple’s iPhone, phones that can serve as Internet-access devices are rapidly gaining popularity.
So, working on Android applications gives you experience with an interesting technology (Android) in a fast-moving market segment (Internet-enabled phones), which is always a good thing. To create an Android application, you will need to create a corresponding Android project. This could be an Eclipse project, if you are using Eclipse for Android development. The project will hold all of your source code, resources (e.g., internationalized strings), third-party JARs, and related materials. The Android build tools whether Eclipse-integrated or stand-alone will turn the contents of your project into an Android package (APK) file, which is the Android application. Those tools will also help you get your APK file onto an Android emulator or an actual Android device for testing purposes.
