In this part of my tutorial I’ll show you how to make an Android toolbar and then show how to switch between screens in App Inventor.
We’ll finish up the icons we made in the previous tutorial. Then I’ll shrink them to size in Photoshop. Then we’ll put the toolbar together in App Inventor and use them to switch screens. The blocks used can be found after the video below.
