The Log Record APIs allow you to customize aspects of logging.
Log records are automatically created when an operation replay fails in the SAP Mobile Server. If an operation replay succeeds, there is no LogRecord created by default (note that an SAP default result checker may write a log record even when the SAP operation succeeds). To get the confirmation when an operation replay succeeds, register a CallbackHandler and implement the CallbackHandler.onReplaySuccess method.
