The Raspberry Pi is a cheap, basic, programmable credit-card sized computer that plugs into your TV and a keyboard. Over five million Raspberry Pi's have been sold worldwide, so farRaspberry Pi in easy steps starts with the basic components you'll need, setting up the system and logging into the console. Then step-by-step it covers; exploring the desktop, the Taskbar, customization, the filesystem and browsing the internet; commanding the system, applications, web pages, reading and writing text, finding files, adding users, changing permissions, and employing the shell; animating with Scratch, enabling complete beginners to create computer programs visually without writing any code; programming with Python a high-level (human-readable) programming language; producing games Raspberry Pi ships with a selection of Python games for you to try; developing windowed apps with Tkinter; driving header pins how to control electrical input and output on the Raspberry Pi header from Python scripts, including lighting a lamp, adding more buttons and controlling projects. Use Raspberry Pi in easy steps to have fun going back to basics and creating your own applications. Source code files from the examples featured in this book are available to download free from the In Easy Steps website.
Answer the question "Can we build this for ALL the devices?" with a resounding YES. Learn how to build apps using seven different platforms: Mobile Web, iOS, Android, Windows, RubyMotion, React Native, and Xamarin. Find out which cross-platform solution makes the most sense for your needs, whether you're new to mobile or an experienced developer expanding your options. Start covering all of the mobile world today.
Understanding the idioms, patterns, and quirks of the modern mobile platforms gives you the power to choose how you develop. Over seven weeks you'll build seven different mobile apps using seven different tools. You'll start out with Mobile Web; develop native apps on iOS, Android, and Windows; and finish by building apps for multiple operating systems using the native cross-platform solutions RubyMotion, React Native, and Xamarin.
For each platform, you'll build simple, but non-trivial, apps that consume JSON data, run on multiple screen sizes, or store local data. You'll see how to test, how to build views, and how to structure code. You'll find out how much code it's possible to share, how much of the underlying platform you still need to know, and ultimately, you'll get a firm understanding of how to build apps on whichever devices your users prefer.
This book gives you enough first-hand experience to weigh the trade-offs when building mobile apps. You'll compare writing apps on one platform versus another and understand the benefits and hidden costs of cross-platform tools. You'll get pragmatic, hands-on experience writing apps in a multi-platform world.
What You Need:
You'll need a computer and some experience programming. When we cover iOS, you'll need a Mac, and when we cover Windows Phone you'll need a computer with Windows on it. It's helpful if you have access to an iPhone, Android phone, and Windows Phone to run the examples on the devices where mobile apps are ultimately deployed, but the simulators or emulator versions of those phones work great.
This book covers the entire scope of computer programming and Structured Program Design, from problem identification to maintaining existing programs. It is intended for two audiences: beginning programmers and experienced programmers seeking ways to improve the quality of their software.
