DEVELOPMENT OF HELLO WORLD APPLICATION
AIM:
To designan android application to display Hello World
First stepis to create a simple Android Application using Android studio. When you click on
Android studio icon, it will show screen as shown below
You can start your application development by calling start a new android studio project. in a new
installationframe should ask Application name, package information and location of the project.−

3. 3 | P a g e I I I B . S c ( I T ) / 1 8 U I T S P 5
Configure the Hello World Project Details
We'llfinishcreating the project by configuring some details about its name, location, and the API
version it
Changethe name of the application. Change the default Project location toyour preferred
directory or just leave it as the default location.
On the minimum API level, ensure that API 15: Android 4.0.3 IceCreamSandwich is set as the
Minimum SDK. This ensures that your application runs on almost all devices.

4. 4 | P a g e I I I B . S c ( I T ) / 1 8 U I T S P 5
The next level of installation should contain selecting the activity to mobile, it specifies the default
layout for Applications.

5. 5 | P a g e I I I B . S c ( I T ) / 1 8 U I T S P 5
SOURCE CODE :
TheMain Activity File
Themain activity codeisa Java fileMainActivity.java. Thisis theactual application file which
ultimately gets converted to a Dalvik executable and runs your application
packagecom.example.helloworldapplication;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
TheLayout File
The activity_main.xml is a layout file available in res/layout directory, that is referenced by your
application when building its interface. You will modify this file very frequently to change the
layout of your application. For your "Hello World!" application,this file will have following content
related to default layout −
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:padding="@dimen/padding_medium"
android:text="@string/hello_world"
tools:context=".MainActivity" />

6. 6 | P a g e I I I B . S c ( I T ) / 1 8 U I T S P 5
I )Running app on Phone:
Connect your Phone toComputer
Plug in your device toyour computer with a USB cable. If you're developing on Windows, you might need
to install this universal ADB USB driver or find your specific USB driver for your device.
Enable USB Debugging
The next stepis to enable USB debugging soyour phone can interact with your computer in a developer mode.
The following steps are needed:
1. (Windows Only) Install this ADBDriver
2. Plug-inyour Android Device to Computer via USB
3. Open the "Settings" App on the Device
4. Scroll down to bottom to find "About phone" item
5. Scroll down to bottom to find "Build number" section
6. Tapon "Build Number" 7 times in quick succession
7. You should see the message "Youare now a developer!"
8. Go back to main "Settings" page
9. Scroll down bottom to find "Developer options" item
10. Turn on "USB Debugging" switch and hit "OK"
11. Unplug and re-plug the device
12. Dialog appears "Allow USB Debugging?"
13. Check"Always allow from this computer" and then hit "OK"

7. 7 | P a g e I I I B . S c ( I T ) / 1 8 U I T S P 5
Running your App
Now, we can launch apps from Android Studio onto our device:
1. Select one of your projects and click "Run" from the toolbar.
2. In the "Choose Device" window that appears,select the "Choose a running device" radio button, select the
device, and click OK.
II)Running app on Emulator(AVD)
To run the app from Android studio, open one of your project's activity files and click Run icon from the tool
bar. Android studio installs the app on your AVD and starts it and if everything is fine with your set-up and
application,it willdisplay following Emulator window −Once Gradle finishes building,Android Studio should install
the app on your connected device and start it.
