Quotes Generator App Using MIT App Inventor 2

Introduction

In this tutorial, you will learn how to create a motivational quotes generator app using MIT App Inventor 2, leveraging a free API for generating quotes. This step-by-step guide will walk you through the necessary components to build your app effectively.

Step 1: Setting Up Your Project

1. Start a New Project:

   • Open MIT App Inventor and click on "Start new project."
   • Name your project "Quotes."

2. Designing the User Interface:

   • Add one Level component for your main layout.
   • Inside this Level, add a Vertical Arrangement.
   • Place a Button within the Vertical Arrangement for fetching quotes.
   • Add a Label (hidden initially) to display the motivational quotes.

3. Customizing Design Elements:

   • Change the Button text to "Get Quote."
   • Adjust the Button's background color and text size to make it visually appealing.
   • Set the Label to display "Motivational Quotes" with a larger font size and bold style.
   • Align all elements to the center of the screen and adjust the Label's background color to be semi-transparent.

Step 2: Integrating the API

1. Using the Quotes API:

   • Utilize the free quotes API at https://type.fit/api/quotes. This API contains a vast collection of motivational quotes that will be fetched by your app.
   • In MIT App Inventor, navigate to the left sidebar, find the 'Connectivity' section, and drag the Web component into your project.

2. Setting Up API Calls:

   • On the Button click event, set the Web component to call the quotes API. Make sure to paste the URL into the Web component's properties.
   • Use the "Get" method after setting the URL so that the app fetches data from the API.

3. Handling the API Response:

   • Create a global variable named 'response' to store your fetched quotes.
   • Use the "JSON Text Decode" block to convert the response from the API into a dictionary format.
   • Extract a random quote from the list of quotes returned. To do this, set the Label text to show the value corresponding to the "text" key.

4. Implementing Random Selection:

   • Create a block to select a random item from the response list, ensuring that you define the range correctly (e.g., 1 to 200) to avoid errors.

Step 3: Testing Your App

• After finishing the setup, use the emulator to check your app's functionality. Click the "Get Quote" button to see a new motivational quote display each time.

With the completion of these steps, you have successfully created a motivational quotes generator app using MIT App Inventor 2!
