LiveCode Builder • Creating an extension library with ChatGPT

$

Having the need to list, on a Android device, the names (SSIDs) of available WiFi (all), I decided to give it a try to build it with the help of ChatGPT.
Amazingly, I got back a lot of stuff that seemed like a complete set of instructions for using Livecode builder.
PS: Then I've got stuck on Step 4

This was my question to chatGPT:
Please write the code, to create a Livecode script builder extension for Livecode.
The LCB extension should be used on Android 10 or android 11, in order to return a list of all the available WiFi names (SSID's) on the device which runs the Livecode standalone. The list of wifi names must include both those to which you have already been connected and those that have not. The extension should include all the code to make it working and all its Livecode dictionary entries, which explain how to use it.
An this was the answer:
To create a LiveCode Builder (LCB) extension that returns a list of all available WiFi SSIDs on an Android device, we need to write a combination of LCB and Java code. The LCB code will call the Java methods, which interact with Android APIs to fetch the WiFi SSIDs. Here's a step-by-step guide:

Step 1: Create the Project Structure
Create Project Directory:
Create a directory named WiFiExtension.

Create Directory Structure:
Inside WiFiExtension, create the following subdirectories:

android
resources
Step 2: Write the Java Code
Inside the android directory, create a file named WiFiHelper.java with the following content:

CODE:

package com.example.wifiextension;import android.content.Context;import android.net.wifi.WifiManager;import android.net.wifi.ScanResult;import java.util.List;import java.util.ArrayList;public class WiFiHelper {    private WifiManager wifiManager;    public WiFiHelper(Context context) {        this.wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);    }    public String[] getAvailableSSIDs() {        List<ScanResult> scanResults = wifiManager.getScanResults();        List<String> ssidList = new ArrayList<>();        for (ScanResult scanResult : scanResults) {            if (scanResult.SSID != null && !scanResult.SSID.isEmpty()) {                ssidList.add(scanResult.SSID);            }        }        return ssidList.toArray(new String[0]);    }}
Step 3: Write the LiveCode Builder (LCB) Code
In the WiFiExtension directory, create a file named WiFiExtension.lcb with the following content:

CODE:

module WiFiExtensionuse com.livecode.foreignuse com.livecode.systemuse com.livecode.mobileprivate variable mWiFiHelper as optional javalibrarymetadata title is "WiFiExtension"metadata author is "Your Name"metadata version is "1.0"metadata platform is "android"metadata description is "A LiveCode extension to fetch available WiFi SSIDs."public handler Initialize    if the environment is not "android" then        log "WiFiExtension can only be used on Android."        exit to top    end if    if mWiFiHelper is empty then        put foreign library "com.example.wifiextension.WiFiHelper" into mWiFiHelper        put the result into mWiFiHelper        if mWiFiHelper is empty then            log "Failed to load WiFiHelper library."            exit to top        end if    end ifend handlerpublic handler GetAvailableSSIDs() returns list    variable context as object    put mobileGetContext() into context        variable wifiHelper as object    put mWiFiHelper.create(context) into wifiHelper        variable ssids as list    put wifiHelper.getAvailableSSIDs() into ssids        return ssidsend handlerend module
Step 4: Compile the Java Code
Set up the Android SDK: Make sure you have the Android SDK installed and configured.

Compile the Java Code:
Navigate to the WiFiExtension/android directory and compile the WiFiHelper.java file to generate the WiFiHelper.class file.

Create a JAR file:

CODE:

jar cf WiFiHelper.jar com/example/wifiextension/WiFiHelper.class
Step 5: Package the Extension
Copy the JAR File:
Copy the WiFiHelper.jar file to the WiFiExtension/resources directory.

Create Extension Manifest:
In the WiFiExtension directory, create a file named WiFiExtension.lce with the following content:

CODE:

<widget name="WiFiExtension"        version="1.0"        license="MIT"        platforms="android"        author="Your Name"        description="A LiveCode extension to fetch available WiFi SSIDs.">    <libraries>        <library src="resources/WiFiHelper.jar" platform="android" />    </libraries>    <components>        <component name="WiFiExtension" />    </components></widget>
Step 6: Load and Use the Extension in LiveCode
What follows is how to use the LC Extension manager, with I knew.

Ok, the problem is that I have no idea how and if I can compile Java code (I am on OSX Sonoma, LC10).
I follow all the instructions but when I type on the terminal:

CODE:

javac com/example/wifiextension/WiFiHelper.java
even if the file is there I get back what follows, which I don't understand.
Any help would be appreciated.
Thanks
