Figure 4.8 shows Resume, Disconnect, Step Over, Step Return, etc buttons.
In the version of ADT (v22.3.0-887826) I am running, that debug toolbar is missing.
I found the solution at StackOverflow. You need to click on the down arrow button at the top right and there is a dropdown menu to Show Debug Toolbar.
