Use this link . It shows a similar error. The solution is to add a network_security_config.xml file and update your manifest file.

newtwork_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
        <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">api.example.com(to be adjusted)</domain>
        </domain-config>
</network-security-config>

If this doesn't work, consider changing the url from "http" to "https".
