Now your new project is created.

In Android there are two main types of files.
  • .java and
  • .xml
.java files contains the java codes and xml files contains the xml code. XML is used to design the layout of the android app.

By default a basic android activity contains a TextView with the text Hello World. We will discuss later what is TextView or what is activity. But right now just learn the basics of Android studio. 

To run the app
  • click on the run icon or press Ctrl+F10.
  • choose the device you are going to run your app on and click ok.

Congratulations you just created your first android app in android studio.
