I have just started learning android and am not able to understand what an activity is. My question is, is creating an activity same as creating a new class? A class is just referred as an activity in android. Also can't a UI screen have multiple java classes or one UI page will have only one java class?

  • One screen can have multiple classes attached... They're called fragments... – Kushan Sep 10 '18 at 22:43

From https://developer.android.com/reference/android/app/Activity

An activity is a single, focused thing that the user can do. Almost all activities interact with the user, so the Activity class takes care of creating a window for you in which you can place your UI with setContentView(View)

We can say Activity is a Java class that the user can interact with.
