Issue while creating a debug build ionic.

Comienza reproduciendo ionic cordova build android --debug e inspecciona el fallo reportado de :app:processDebugResources en el proyecto Android generado. La carga útil apunta a merged_manifests\debug\AndroidManifest.xml y al recurso xml/network_security_config ausente; se considera completado determinar si la CLI o el proyecto generado es responsable de ese fallo.
