AppTest1 - Simple Calculator
Application description
AppTest1 is a simple yet functional Android application that allows users to perform basic mathematical operations. In its current version, the app focuses on the operation of adding two integers, offering an intuitive and accessible user interface.
Functionality
The application features a clean and minimalist interface, designed following Material Design guidelines. Upon startup, the user is greeted with a welcome message that introduces the app. The main screen includes three input fields:

A field to enter the first number
A field to enter the second number
A field to display the result

Between the first and second fields there is a "+" symbol which indicates the operation that will be performed. In the center of the screen is a "Sum" button which, when pressed, activates the main functionality of the app.
How to use it
Using AppTest1 is extremely simple:

Enter an integer in the first field
Enter another integer in the second field
Press the "Sum" button
Immediately display the result in the lower field

The app also includes error handling features: if one or both fields are left blank, or if non-numeric characters are entered, the app will display a message prompting the user to enter valid numbers.
