As we are creating a basic application I choose Empty activity as my template.Then click Finish.Then a Project  will be created . This may take couple of minitues based on the PC you are using. Click the project tab which I have highlighted in the left corner to get the whole project. Then go through each and every component in it. Go to app>src>main>res>layout>activity_main.xml to get the w...
