User identifier
User identifier can be specified by calling:
Smartlook.setUserIdentifier(String key);
Identifiers can be found in the Dashboard and are very useful for finding specific user’s recordings.
User properties
Additional custom properties can be added by calling:
Smartlook.setUserIdentifier('user_id', { "property_key" : "property_value"});
These properties can be seen in the Dashboard at Visitor details.
