An Android application consists of one or more than one screen. The android developers define a special structure for each screen in an application. These structures are called "class".
How can I express it in one sentence? ( My intention is to specify the number of classes and screens in the application must be equal )
The developers should define as many classes as the number of screens in the application.
The developers should define a class for every window in the application.
Are they correct?
If they are not, how can I express this?
