Step 4- Now after deleting the code you create more activities, you have two options for creating an activity. The first one is the previous method and the second is that you click on the class file and press Ctrl C and then Ctrl V and then change the activity name and  you simplt make the layout section also.

Step 6- Now in Home activity we add two buttons in layout and set the name. We have two options; first, we create a button with code and second, we drag and drop, but this is not a good practice. Now I am showing code as well as button.
