Addition

The document contains an XML layout file for an Android application with a vertical LinearLayout that includes two TextViews for input labels, two EditTexts for number inputs, and a Button for performing addition. The accompanying Java file defines a MainActivity class that handles user input, performs the addition of the two numbers, and displays the result in a third EditText. The application is designed to take two numbers from the user and output their sum when the button is clicked.
