The "ERR_UNKNOWN_URL_SCHEME" error typically occurs when a web page tries to open a URL with a scheme that is not supported by the WebView component in Android apps. In this case, the "whatsapp://" scheme is likely not recognized.
To resolve this issue, you can try using the "intent://" scheme instead of "whatsapp://". Here's an example of how you might modify your link:
```html
<a href="intent://send?text=https%3A%2F%2Fekemart.in%2Fproduct-detail.php%3Fproid%3D59%26shopid%3D38#Intent;scheme=whatsapp;package=com.whatsapp;end">Share on WhatsApp</a>
```
This intent-based link should open the WhatsApp app and prompt the user to share the given text. Ensure that the user has WhatsApp installed on their device for this to work.
Make sure to test this thoroughly to ensure compatibility across different devices and WhatsApp versions.
