Question No.2 Develop a Stopwatch App in Android Studio. It should have 3 features 1. Start 2. Stop 3. Reset Solution: Create a Stopwatch App using Android Studio The layout for Stopwatch includes: 

A TextView: showing how much time has passed



Three Buttons: 1. Start: To start the stopwatch 2. Stop: To stop the stopwatch 3. Reset: To reset the stopwatch to 00:00:00

Steps to create the Stopwatch: 

Create a new project for Stopwatch App



Add String resources



Update the Stopwatch layout code



Update the code for activity

Below are the steps one by one in detail: 1. Create a new project for Stopwatch App 

Create a new Android project for an application named “Stopwatch” with a company domain of “taimoorshan.org”, making the package name “org.taimoorshan.stopwatch”

Create a New project and select Empty Activity

Configure the project



The minimum SDK should be API 14 so it can run on almost all devices.



An empty activity called “StopwatchActivity” and a layout called “activity_stopwatch” will be created.

2. Add String resources We are going to use three String values in our stopwatch layout, one for the text value of each button. These values are String resources, so they need to be added to strings.xml. Add the String values below to your version of strings.xml: Srtings.xml

3. Update the Stopwatch layout code

Here is the XML for the layout. It describes a single text view that s used to display the

timer, and three buttons to control the stopwatch. Replace the XML currently in activity_stopwatch.xml with the XML shown here:
