Just Maths - Android Activities and Layouts
Let's start creating our first app - Just Maths. This will be a small app to introduce you to the various aspects of Android App Development - starting with activities and layouts. So just jump right in. What is Activity? Activity is just a single screen. Yes it is that simple. So in our case - Main Menu Screen is one activity, Game Screen is another activity and Score Screen is another activity. Activity is a screen that displays some information to the user or requires some input from the user. Activity handles the interaction with the user.
