This talk will give you an introduction to Processing for Android. It will cover the basics of the Processing language that allows to effectively program interactive graphics in 2D and 3D, and will describe the application of these techniques to different types of Android devices: smartphones, tablets, wearables and smartwatches, as well as to Cardboard-compatible devices in order to create VR experiences. Processing started in 2001 at the MIT Media lab as a project to increase software literacy in the arts and design, and today it is used around the world as a teaching and production tool. An advantage of Processing for Android over more complex programming environments is that it allows the users to focus on the interactions and visual output of their code rather than in the implementation details of the Android platform.
