I'm trying to learn Android development. I'm clicking the template for "Empty Activity," which shows a nice Material Toolbar with a back button. However, I don't see it when I view the main layout xml file. Am I doing something wrong? Is it supposed to be like this? The tutorial shows it differently than mine:

  Android studio changed those templates a while ago, probably the codelab, which you are trying to follow, is outdated.

  From what i see, you have the exact same code, probably the rendering inside Android Studio changed inside the last half year, so they don't display it anymore. Just continue the codelab, when you will run in on a device, it will look just fine.
