Let’s Build a Simple Hello World App

Requirements

As blocky is a javascript library this helps us to create android apps directly from your web browser and thus you need:

• Browser
• Internet Connection

Note: Offline mode also exists.

Step by Step Implementation

Step 1: Go to MIT App Inventor’s creator and log in your using google account and click “start new project“

Step 2: Enter your project name and click “OK“

Step 3: Your empty project will look like this.

Step 4: Now drag and drop the “Button” and “Label” components from Palette.

Step 5: Click on the “Button” component which we dragged and then from right from “properties” change “Button Text” to “Click Me” similarly select “label” and change “label Text” to an empty string. 

Note: Label disappears because we changed its text to an empty string.

Step 6: That is enough for the Designer view now to switch to “Block” from the top right corner. Click on a component to access respective blocks and drag and drop the required one.

We will use simple logic. When the user clicks on the button app must change the label text to “Hello World!”

Our app is ready now we just need to export in. From the menu click “Build” and select whether you want to apk to be downloaded to the computer or generate a downloadable QR code with a link. Now simply install it on your device.

Output:

With the spread of smartphones, smartphone technology improved exponentially and thus smartphones occupied a huge part of the market. To meet the requirement of the user and seeing the wide-open market there came different operating systems like Android, iOS, etc but for the sake of this article, we gonna talk specifically about how Android Development changed and what it looks like today. Today for making an Android App you don’t need to learn any programming language. Little strange, right!. Yes, but, indeed, you don’t need to learn programming language but you just need to have problem-solving skills. I know that learning programming language teaches that but when we say you don’t need programming language it means you don’t need to learn syntax and semantics and the process is too visual that it doesn’t feel like coding when in reality you are doing exactly “coding”. And Yes we will learn to create a simple Android App from this article itself, so enjoy reading!
