Package Name is a unique name given to identify a specific application. Generally, it is in the form of domain.company.application but it is entirely up to you to choose the name.
In Save location, it asks you for the location where you want to save your project.
In Language section, it asks you to choose the language either Java or Kotlin to build your application.
In Minimum API level basically, it asks you to set the minimum Android version for your application to run.
This project will support instant apps is a feature that lets end users use that app without fully downloading onto their phone.

 
Once you filled up all the information, Just click on the Finish button and Android Studio will start to build and synchronize your project.
After we have successfully built our project, Now we will have a tour of the Android Studio user interface.
 
Android Studio User Interface

At the top of the user interface of Android studio, you can see a thin horizontal bar consisting of the labels of drop-down menus.This thin horizontal bar is called Menu Bar.
In Menu Bar we can find the majority of Android Studio’s essential functions and settings such as opening a project, editing tools (cut, copy, paste), running an application, exiting the program and several other functionalities.
 
B – Navigation Bar

It actually shows the path of the current file that we are working on.
The cool thing about the Navigation bar is when you click on any one of the directories its going to show you all the contents of that directory.

At the right side of the Navigation bar, we can see a horizontal bar with clickable icons that performs specific functions.This horizontal bar is known as Toolbar.
A toolbar is shortcuts of more commonly used features of the program.
They are intended to provide instant access to the user’s commonly used functions.
