    If you are running in localhost you should use http://10.0.2.2:8080/ as a base url, you need to specify the port, otherwise it won’t work.

    Can you do simple test in your emulator.
    From your emulator.
    Can you open your browser. After that, open your URL. (10.0.2.2)
    If everything good.
    Then you need to setup network_config in your android manifest.
    Please check https://developer.android.com/training/articles/security-config

    <?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">10.0.2.2</domain>
    </domain-config>
    <base-config cleartextTrafficPermitted="false" />
</network-security-config>
