CertificateStatusListener (Avaya Client Services API Reference (Android))

```
public interface CertificateStatusListener
```
Certificate status listener interface is implemented by the client applications wishing to be notified about the certificate's status.
Client applications can register multiple status listeners by calling CertificateManager.addCertificateStatusListener(CertificateStatusListener). The listeners would be notified via onCertificateExpiryNotification(X509Certificate, int). The callback method onCertificateExpiryNotification(X509Certificate, int) notifies the expiration details only for the client identity certificate. Client application can configure such notification commencement period by calling SecurityPolicyConfiguration.setCertificateRenewalValue(int).

If client application does not wish to be notified any longer they can remove the listener by calling CertificateManager.removeCertificateStatusListener(CertificateStatusListener) or choose not to register the listener.
