Android Service Implementation Guide

This document provides code for a service demo application in Android Studio. The application contains an activity layout with buttons to start and stop a service. The MainActivity class handles button clicks to start and stop the MyService class. The MyService class extends the Service class and implements methods to start the service and display a toast notification, and stop the service and display a toast notification. The goal is to demonstrate how to create and use a service in Android.
