How to implement SSL certificate connection in your project to ensure a secure connection?

To connect an SSL certificate in an Android project, HTTPS connection to a server already configured for SSL is usually used. It is important to ensure that all network requests go through HTTPS in the app. If you need to use a self-signed or custom certificate, you can add it to res/raw and configure the Network Security Config.

Example of configuring Network Security Config for a custom certificate:

<!-- res/xml/network_security_config.xml -->
<network-security-config>
    <domain-config>
        <domain includeSubdomains="true">example.com</domain>
        <trust-anchors>
            <certificates src="raw/my_cert" />
        </trust-anchors>
    </domain-config>
</network-security-config>

And connect it in the manifest:

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

Thus, the application will trust the specified certificate when establishing a secure connection.
