NetworkSecurityConfig: No Network Security Config specified, using platform default

The Network Security Configuration feature lets apps customize their network security settings in a safe, declarative configuration file without modifying app code. These settings can be configured for specific domains and for a specific app. The key capabilities of this feature are as follows:

• Custom trust anchors: Customize which Certificate Authorities (CA) are trusted for an app’s secure connections. For example, trusting particular self-signed certificates or restricting the set of public CAs that the app trusts.
• Debug-only overrides: Safely debug secure connections in an app without added risk to the installed base.
• Cleartext traffic opt-out: Protect apps from accidental usage of cleartext traffic.
• Certificate pinning: Restrict an app’s secure connection to particular certificates.
