I have written code in apex class ,I want to check the url belongs to classic or Lightining

string UrlDomainName  = URL.getSalesforceBaseUrl().getHost();
               // classic code
                // lightining code

what i have to write instead of classic view for finding classic url,please anyone help me to rectify this issue


URL checking is not ideal way of detecting user's current mode. There is a better way.


This method returns a string from the following list.

Theme1—Obsolete Salesforce theme

Theme2—Salesforce Classic 2005 user interface theme

Theme3—Salesforce Classic 2010 user interface theme

Theme4d—Modern “Lightning Experience” Salesforce theme

Theme4t—Salesforce mobile app theme

Theme4u—Lightning Console theme

PortalDefault—Salesforce Customer Portal theme

Webstore—Salesforce AppExchange theme

Theme3 should be classic and Theme4d is for LEX. More details here.

if(UserInfo.getUiThemeDisplayed() == 'Theme3')
//classic code
else if(UserInfo.getUiThemeDisplayed() == 'Theme4d')
// LEX code
