In the next screen ,enter your application name.Here,I am going to enter it as “My Application”.

Then,enter your company name.The company name can be anything .Here,I am entering it as “mobile2computer.com”.

Select the type of device you are going to target i.e the device in which you are going to use the app.We are going to make the app for the mobile phone,so select the “Phone ad Tablet” checkbox and click “Next”.

Then,Select the type of activity you want.Here, we have to select “Empty Activity” for our app.

In the next screen Android Studio will ask about customizing the Activity.By default the Activity name will be “Mainactivity” and Layout name will be “activity_main”.If you wan to change it you can change it.Then,click on  “Finish”.

You will be shown a  box like below.The project is now building.

 

STEP 3: MAKING THE ANDROID APP

After the project is built you will be able to see the below screen.Then,click on “activity_main.xml”.

 

We can see the layout of the app and how would the app look.Our app would display “HelloWorld!”.To change the word you can follow the below steps.

Click on “Text” button at the bottom ,as shown in the below image.

 

Then you would be able to see the below screen.

If you want to change the “Hello World!” and use your own sentence ,then change the sentence as anything like “Hello Guys,Welcome to my app” in the TextView.
Enter, android:text=”Hello Guys,Welcome to my app”  instead of android:text=”Hello World!”



Then, click on “Design” in the bottom of the screen.As shown in the below image.

Now ,we can see that the wordings have been changed.

 

STEP 4:TESTING AND BUILDING THE APP

  For testing the app we are going to use our android phone.For that you should be a developer. Go to Settings -> About Phone ->Device Information.Then fast click “Build Number” several times.Now you will see a dialog box saying you are now a developer.
  To test the app on your Android smartphone:-
   
  Connect your Android Smartphone with PC or Laptop using the USB cable
  You will get the Below screen in your phone.Click on “USB Debugging (ADB)”
    Clicking on that will show the following pop up dialog box.Click “OK”
       You will be asked permission to “Allow USB debugging”  .Click “OK”
    Now the app will run o the phone and you will be able to see that on your computer screen too.Below is an image of the app we built and it’s running on our phone.
