Summary: In this lesson, we will wrap up our three-video discussion on activities. Here, we will review the button and the event associated with it. We will make minor modifications to the layout to be able to see the text view and we will validate the button click event. Then, we will move to activities and their lifecycle. We will look at the stages the activity is going through. To do that, we will override the needed methods, and log them to the logcat to see what happens as we load the application and go from one activity to the other.
