Creating a complete Kodular extension with source code and example

Creating a complete Kodular extension with source code and example would be too extensive for a single response. However, I can give you a simplified example of a Kodular extension to get you started. In this example, I’ll create a simple extension that generates a random number within a specified range.

Step 1: Set Up Your Development Environment

You’ll need a Java development environment (e.g., Android Studio) to create your Kodular extension.

Step 2: Create a Java Class

Create a new Java class that will define your extension. Let’s call it RandomNumberExtension.

				
					package com.example.randomnumberextension;

import com.google.appinventor.components.annotations.SimpleFunction;
import com.google.appinventor.components.annotations.SimpleObject;

import java.util.Random;

@SimpleObject(external = true)
public class RandomNumberExtension {

    @SimpleFunction(description = "Generate a random number between the specified range.")
    public int GenerateRandomNumber(int min, int max) {
        Random random = new Random();
        return random.nextInt(max - min + 1) + min;
    }
}

In this code, we’ve defined a class RandomNumberExtension with a method GenerateRandomNumber that takes a minimum and maximum value as parameters and returns a random number within that range.

Step 3: Build Your Extension

Build your extension as a .jar file using your Java development environment.

Step 4: Package Your Extension

Create a .aix file (Kodular extension file). You can use the Kodular Extension Builder tool to help you create this file. Be sure to specify the extension’s name, version, and description in the builder tool.

Step 5: Upload Your Extension to Kodular

Log in to your Kodular account.
Go to the “My Extensions” section.
Click on the “Upload Extension” button.
Provide the .aix file you created and fill in the required information about your extension.

Step 6: Use Your Extension in a Kodular Project

In your Kodular project:

Open the “Extension” section.
Add your uploaded extension to your project.

Step 7: Program Your App

Use the blocks provided by your extension in your Kodular app. For this example, you can use the “GenerateRandomNumber” function from your extension.

Step 8: Build and Test Your App

Build and test your Kodular app with the custom extension.

Please note that this is a simplified example for educational purposes. Real-world extensions can be more complex and may require additional considerations. You can adapt this example to your specific needs and explore the official Kodular documentation and forums for more advanced extension development.
