Android N java.security.cert.CertPathValidatorException: Trust anchor for certification path not found

In my application i use a self signed certificate to connect over https. The application works perfectly fine when the compilesdk is set to < 24, however when the compilesdk is set to 24 my application fails to connect to the server over https and throws the following exception:

I followed the steps mentioned here https://developer.android.com/preview/features/security-config.html, however my app still fails to connect to the server over https. My network_security_config.xml is as below:

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config>
        <domain includeSubdomains="true">test.abc.com</domain>
        <trust-anchors>
            <certificates src="@raw/ca_norton"/>
        </trust-anchors>
    </domain-config>
</network-security-config>

In my AndroidManifest.xml included the following under the application tag 

 <meta-data android:name="android.security.net.config"
            android:resource="@xml/network_security_config" />

ca_norton.crt is also copied into the raw folder. Am i missing something here? Thanks in advance.

The correct way to specify a Network Security Config in your manifest is:

<?xml version="1.0" encoding="utf-8"?>
<manifest ... >
    <application android:networkSecurityConfig="@xml/network_security_config"
           ... >
    ...
    </application>
</manifest>

See https://developer.android.com/preview/features/security-config.html#manifest. The meta-data approach was only present in the early N previews and is no longer supported.
