App Inventor 2: Databases and Files is a step-by-step guide to writing apps that use TinyDB, TinyWebDB, Fusion Tables and data files for information storage and retrieval. Includes detailed explanations, examples, and a link to download sample code. This is the first tutorial to cover all of these App Inventor database and file features. If your apps need to work with data or files - you need this book! TinyDB stores data on your smart phone or tablet and is a primary way for App Inventor apps to save data, even when the app is no longer running or if the device is turned off. TinyWebDB is similar to TinyDB, but stores your data on a remote server in the network cloud. Multiple apps can share a TinyWebDB database, plus you can update the content of your TinyWebDB using just a web browser. This means you can distribute an app whose content can change over time - just by changing the values in TinyWebDB. A big challenge is the need to set up a TinyWebDB server - this book shows how to do that through free services offered by Google. Fusion Tables provide a powerful, cloud-based database system for App Inventor apps. Creating, retrieving, updating and deleting data is done using the industry standard Structured Query Language or SQL. Fusion Tables reside in the Google network cloud - this book shows you how to set up and configure Fusion Tables for you own apps using free services of Google. As your app requirements grow, Google's cloud can provide low cost servers and bandwidth for your needs. Underneath the Android OS user interface, there is a file system, similar to the file system found on Windows or Mac OS X. With App Inventor your apps can write and read data from files, and if using the special "CSV" format, App Inventor data can be shared with many spreadsheet programs. This book shows you how to create, use and access data files, and how to convert data to and from the CSV format. Over 28,000 words. Over 250 screen shots and illustrations. Numerous sample programs and code.

App Inventor 2 Graphics, Animation & Charts
MIT App Inventor is the fast and simple way to develop Android apps. Using a programming system that runs in your Internet browser, just drag and drop user interface components and link together program functions on screen, and then run your app directly on your Android phone or tablet. Learn to create apps using simplified interactive image sprites and to control movement using a finger on the screen or by tilting the phone or tablet. Learn how to use the "Canvas" features for drawing, including a unique way to implement traditional animation features. Includes numerous sample apps, detailed explanations, illustrations, app source code downloads and video tutorials. Volume 4 introduces the use of graphics drawing features, including general graphics features, image sprites, animation and charting. Charting refers to the creation of line, column, scatter plot, and strip recorder charts commonly used in business and finance. This is volume 4 of a 4 volume set. Volume 1 introduces App Inventor programming, Volume 2 introduces advanced features and Volume 3 covers databases and files.

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.
