Hi everyone! 
I’m super excited to share my first extension with you all — the InternetChecker. 
It helps you detect real-time internet connectivity in your app. Hope it helps in your projects! 
What It Does
This extension lets you:
Detect if the device has active internet access (not just if it’s connected to Wi-Fi or mobile).
Check whether Wi-Fi or Mobile Data is turned on or off.
Emit separate success and failure events depending on the result.
How It Works
This extension checks internet access by making a connection to:
https://clients3.google.com/generate_204
This is a lightweight, fast-loading URL that Google uses to verify internet connectivity (similar to how Android detects captive portals). If the response code is 204 (No Content), it confirms there’s actual internet access — not just a connection to a router.

Android Compatibility
This extension uses basic Java 7 and Android APIs to ensure maximum compatibility. It has been tested on:
- Android 7 (Nougat)
- Android 8 (Oreo)
- Android 9 (Pie)
It has not yet been fully tested on Android 10+ (API 29 and above), so there may be behavior differences due to newer Android network security policies.
Feel free to report any issues you experience — I’ll be happy to improve it! 
Important Notes
No source code provided at this time.- Designed as a single component — simple to import and start using.
You can pair this with a Clock component to perform periodic checks every few seconds or minutes.
Thank You!
This is my first extension and I’m truly grateful for your support. 
I hope it’s helpful in your apps, and I’m looking forward to your feedback and suggestions!
