This is a complete tutorial that will help readers make the most of App Inventor 2, even if they have absolutely no programming experience. Learning MIT App Inventor is written from the ground up for today's dramatically improved MIT version of App Inventor. Step by step, mobile expert and instructional specialist Derek Walter guides readers through every App Inventor 2 task and feature in plain, simple English.

MIT App Inventor 2 is the fast and easy way to create custom Android apps for smart phones or tablets. This guide introduces the basic App Inventor features - you can likely create your first simple app in about an hour, and understand the basic components of App Inventor in a full day. App Inventor 2 is free to use and you can use it for commercial applications too. App Inventor 2: Introduction is targeted at adult learners (high school and up) and shows how to design your app’s user interface with “drag and drop” interface controls to layout your app’s screen design. Then implement the app’s behavior with unique “drag and drop” programming blocks to quickly assemble the program in a graphical interface. This introduction covers the basics of the App Inventor user interface Designer and the Blocks programming editor, plus basic “blocks” programming concepts and tools for arithmetic, text processing, event handling, lists and other features. Updates and additional tutorials are available on the book's web site at appinventor.pevest.com

MIT App Inventor 2 is a fast and simple way to create custom Android apps for smart phones or tablets. Volume 2 in the series introduces debugging methods, explains additional controls not covered in Volume 1, introduces “agile” methods for developing a real world app, and provides sample code for using the TinyDB database. This App Inventor 2 series is targeted at adult learners (high school and up). App Inventor 2 provides a simplified “drag and drop” interface to layout your app’s screen design. Then implement the app’s behavior with “drag and drop” programming blocks to quickly assemble a program in a graphical interface. Volume 1 of this series covered the basics of the App Inventor user interface Designer and the Blocks programming editor, plus basic “blocks” programming concepts and tools for arithmetic, text processing, event handling, lists and other features. Volume 2 builds upon Volume 1 to provide tips on debugging programs when the apps work incorrectly, how to us hidden editing features, and how to install your own apps on to your phone or tablet for general use. Code samples are provided for using the Notifier component for general use or for debugging, for user interface control tricks such as buttons that change color continuously or implementing the missing “radio buttons” component, using ListPicker and Spinner for list selections, and using the WebViewer to display web pages in your app. The book includes a large section on designing and building a sample real world application and finishes with a chapter on using the TinyDB database. Chapters Introduction Chapter 1 - App Inventor Tips Chapter 2 - Debugging App Inventor Programs Chapter 3 - User Interface Control Tricks Chapter 4 - Designing and Building a Real World Application Chapter 5 - Tip Calculator Version 2 Chapter 6 - Tip Calculator Version 3 Chapter 7 - Tip Calculator Version 4 Chapter 8 - Tip Calculator Version 5 Chapter 9 – Using the TinyDB database

With the development environment App Inventor 2 you can easily develop and test your own apps. The book is intended to help you get started with setting up the development environment right through to your own apps. It is written for beginners who want to deal with app development, but can also be used for teaching purposes in schools or community colleges. It is a step-by-step guide that does not focus on the full description of the programming language, but uses examples to illustrate the capabilities of the development environment. It starts with setting up the environment and the Android device. It continues with simple apps, via variable concepts and control structures to more complex topics. Event-driven apps are developed, subroutines are handled and sensors are queried. Working with multiple screens is just as important as files and dialogs. The examples are chosen so that the topics with increasing difficulty are treated as systematically as possible. The examples are not too complex to be easily understood. They should serve as inspiration for own projects. A technically strict systematology and a complete description of the programming language is not intended to not overwhelm beginners.

This textbook provides an introduction to the use and understanding of optimization and modeling for upper-level undergraduate students in engineering and mathematics. The formulation of optimization problems is founded through concepts and techniques from operations research: Combinatorial Optimization, Linear Programming, and Integer and Nonlinear Programming (COLIN). Computer Science (CS) is also relevant and important given the applications of algorithms and Apps/algorithms (A) in solving optimization problems. Each chapter provides an overview of the main concepts of optimization according to COLINA, providing examples through App Inventor and AMPL software applications. All apps developed through the text are available for download. Additionally, the text includes links to the University of Wisconsin NEOS server, designed to handle more computing-intensive problems in complex optimization. Readers are encouraged to have some background in calculus, linear algebra, and related mathematics.
