As we know that every activity contains a layout associated with it, so it can be said that the activity class is the gateway, through which a user can interact programmatically with the UI. Every activity contains the layout, which has a user interface to interact with the user. So it can be said that An activity is the entry point for interacting with the user. Unlike most programming languages, in which the main() method is the entry point for that program or application to start its execution, the android operating system initiates the code in an Activity instance by invoking specific callback methods that correspond to specific stages of its Lifecycle. Any app, don’t matter how small it is (in terms of code and scalability), has at least one Activity class.
