method 1 :This method works for all domains also with Android 9. Add this property to your Manifest like this:

 <application
    ...
   android:usesCleartextTraffic="true"
    ...>
 </application>

method 2.1 : Add @xml/network_security_config into your resources:

    <?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">www.rcub.ac.in/</domain>
    </domain-config>
</network-security-config>

2.2 : Add this security config to your Manifest like this:

<application
    ...
    android:networkSecurityConfig="@xml/network_security_config"
    ...>

    ...
</application>
