Programming in Java Online Textbook

computer_teacher — Mon, 07 Mar 2011 04:31:46 +0000

Here is another online programming textbook from Princeton, Introduction to Programming in Java. It teaches the classic elements of programming, using an "objects-in-the-middle" approach that emphasizes data abstraction. The author uses specific applications, taken from fields ranging from materials science to genomics to astrophysics to internet commerce, to teach and demonstrate the programming concepts and techniques presented. Also available are hundreds of easily downloadable Java programs and real-world data sets.

Chapter 1: Elements of Programming
introduces variables; assignment statements; built-in types of data; conditionals and loops; arrays; and input/output, including graphics and sound.

In such cases there’s an explicit note about it next to a module name – i.g. stripScripts() method from “String (String.prototype)” can be called as ‘foo’.stripScripts(), When a module is also a class, there’s a “(constructor)” note next to it – i.g. “Hash (constructor)” means that it should be called as new Hash(), There are few bonus items (such as those from Prototype.Browser) which are not yet included in documentation

Programming for the Android Platform

computer_teacher — Thu, 10 Feb 2011 04:04:47 +0000

Here is an online mobile programming course: Programming for the Android Platform, Developing Wireless Mobile Applications. The goal of this Android programming tutorial course is to teach the technical aspects of how to program Android devices and use the Andoid API, with particular emphasis on scientific and educational applications. This platform is literally booming at this time as more than 300,000 new Android smartphones are activated per day.

Unlike the iPhone, Android is designed to run on many devices produced by many hardware manufacturers, and is based on free, open-source resources. It is programmed with a combination of Java and XML. One can develop programs on an emulator running on a regular computer, so it isn't even necessary to have an Android device to begin writing programs. There is a powerful and very well documented Software Development Kit (SDK) that is freely available, a comprehensive Interactive Development Environment (IDE) called Eclipse with an Android plugin that is free, and the Java and XML (with their editors, compilers, and interpreters) with which one programs Android devices are also free.

5 Android Programming Books

computer_teacher — Fri, 28 Jan 2011 06:05:15 +0000

Here are 5 Android Programming books to help you learn how to develop and build Android mobile applications.

Android is an open source platform built by Google that includes an operating system, middleware, and applications for the development of devices employing wireless communications. It is really a software platform, rather than just an OS, and will probably be used in the future in a much wider range of devices than just smart phones. In practical terms, Android is an application framework on top of Linux, which facilitates its rapid deployment in many domains. Android is open source and a majority of the source is licensed under Apache2, allowing adopters to add additional proprietary value in the Android source without source distribution requirements. Also check out my previous post on some descriptive Android developer guides and presentations.

8 Android Development Guides and 4 Android Presentations

computer_teacher — Thu, 20 Jan 2011 04:10:45 +0000

For those new to mobile app development, Android is an operating system for mobile devices developed by Google and the Open Handset Alliance. It supports smartphones similar to Apple iPhone, Palm webOS, RIM BlackBerry, Windows Mobile, BREW MP, and others. The Android operating system has opened mobile phone development to many developers who haven’t had access to tools for building mobile applications in the past. Experienced mobile developers can now expand into the Android platform, leveraging its unique features to enhance existing products or create innovative new ones.
If you are interested in programming for Android, you will need at least basic understanding of how to program in Java. Android programming is done using Java syntax, plus a class library that resembles a subset of the Java SE library (plus Android-specific extensions). Google provides the Android Development Tools (ADT) for Eclipse to develop Android applications. It provides tools, including a compiler, debugger, a device emulator, as well as its own Java virtual machine (Dalvik), which uses a special bytecode. Android supports 2-D and 3-D graphics using the OpenGL libraries and supports data storage in a SQLLite database.

The following are links and descriptions for 8 Android Application Development Guides and Papers, and 4 Android Development Slide Presentations. These will help you start programming for Android, and learn how to code and start developing and building Android applications.
