Android Development for Beginners 21
In this video tutorial I will provide you with an App Inventor Paint App example tutorial. I make the entire app in this one video.
Specifically we’ll look at what we can do with the canvas component. It allows you to draw curves, straight lines, circles, text and text on an angle. We’ll make a palette of colors, provide for the ability to load and save files to a database. All of the blocks used follow the video below. Here is the finished app for download.
