Mobile Computing with App Inventor – CS Principles

Learn to use the open development tool, App Inventor, to program on Android devices. You will learn how to design and build mobile apps -- apps that are aware of their location, send and receive text messages, and give advice and directions. The only limit on the types of apps you will learn to build is your own imagination!
