This method is called by certificate provider to asynchronously report the result for the getCertificate method. onGetCertificateSuccess is called after the certificate provider successfully obtains the x509KeyManager object. This method is only used in the SAP Mobile Platform registration case, where getCertificate is called.

This method is called by the certificate provider to asynchronously report the result for the getCertificate method. onGetCertificateFailure is called when the certificate provider fails to get the certificate. This method is only used in the SAP Mobile Platform registration case, where getCertificate is called.

In the non-SAP Mobile Platform case, the initialize method is the main method called by the Logon plugin to asynchronously get the client certificate from the certificate provider (in the SAP Mobile Platform case, this method is not called and the getCertificate method is called instead).

In the SAP Mobile Platform registration case, the getCertificate method is the main method called by the Logon plugin to asynchronously get the client certificate from the certificate provider (in the non-SAP Mobile Platform case, this method is not called and the initialize method is called instead). The provided certificate is used to authenticate the client with the server. For Android, the method expects the certificate provider to provide an X509KeyManager object by calling the onGetCertificateSuccess method on the provided CertificateProviderListener callback object.

The synchronous method to return the cached certificate from the certificate provider. The certificate provider can cache the certificate once it successfully retrieves or generates it. If there is no cached certificate, null can be returned.

This function is called when the certificate provided by the provider no longer works to authenticate against the server (for example, if the certificate is expired). This function clears the cached certificate if there is one.

The setParameters method is is not required to do anything. This function is called with the Android Activity object, so that the provider can show UI if it needs to.
