With a foreword by Gitanjali Rao, Time Magazine’s inaugural Kid of the Year, this engaging guide from MITeen Press teaches anyone to design and publish their own apps—no experience necessary!—and introduces young app creators from around the world. Have you ever wanted to build your own mobile apps? App Inventor, a free and revolutionary online program from MIT, lets you do just that. With the help of this companion guide chock-full of colorful graphics and easy-to-follow instructions, readers can learn how to create six different apps, including a working piano, a maze game, and even their own chat app to communicate with friends—then use what they’ve learned to build apps of their own imagination. User-friendly code blocks that snap together allow even beginners to quickly create working apps. Readers will also learn about young inventors already using their own apps to make a difference in their communities, such as the girls from Moldova whose app helps alert residents when local well water is contaminated. Or the boys from Malden, Massachusetts, whose app lets users geotag potholes to alert city hall when repairs are needed. With this inspiring guide, curious young dreamers can become real inventors with real-world impact.

A guide to using App Inventor to create Android applications presents step-by-step instructions for a variety of projects, including creating location-aware apps, data storage, and decision-making apps.

Learn to build mobile apps for Android devices with MIT App Inventor, a visual drag-and-drop programming language like Scratch. You've swiped and tapped your way through countless apps, but have you ever created one? Now you can, thanks to Learn to Program with App Inventor. In less than an hour, you'll be able to build and run your first app! App Inventor is a free software for making Android apps. All you need is a PC with an Internet connection to build your app, and a mobile phone for testing. You'll use a simple drag-and-drop interface, which minimizes errors and avoids too much typing. A certified App Inventor Master Trainer, Logan breaks down each project into logical steps, lists the components you'll need, and then shows you how to create screen designs, control program flow with conditionals and loops, and store data in variables and lists. Once you've tested the app on your phone, you can test what you learned with challenges at the end of each chapter. You'll build cool apps like: * Hi, World!: Use your voice to send a text message * Practice Makes Perfect: Rehearse a speech or dance routine with this video recording app * Fruit Loot: Catch randomly failing fruit in this exciting game * Beat the Bus: Track a friend's journey using location services and maps * Virtual Shades: Take a selfie, then try on some virtual sunglasses Join the 6 million people who have tried App Inventor, and make the journey from app user to app inventor.

With MIT’s App Inventor 2, anyone can build complete, working Android apps—without writing code! This complete tutorial will help you do just that, even if you have absolutely no programming experience. Unlike books focused on the obsolete Google version, Learning MIT App Inventor is written from the ground up for MIT’s dramatically updated Version 2. The authors guide you step-by-step through every task and feature, showing you how to create apps by dragging, dropping, and connecting puzzle pieces—not writing code. As you learn, you’ll also master expert design and development techniques you can build on if you ever do want to write code. Through hands-on projects, you’ll master features ranging from GPS to animation, build high-quality user interfaces, make everything work, and test it all with App Inventor’s emulator. (You won’t even need an Android device!) All examples for this book are available at theapplanet.com/appinventor Coverage includes: Understanding mobile devices and how mobile apps run on them Planning your app's behavior and appearance with the Designer Using the Blocks Editor to tell your app what to do and how to do it Creating variables and learning how to use them effectively Using procedures to group and reuse pieces of code in larger, more complicated apps Storing data in lists and databases Using App Inventor's gaming, animation, and media features Creating more sophisticated apps by using multiple screens Integrating sensors to make your app location-aware Debugging apps and fixing problems Combining creativity and logical thinking to envision more complex apps
