Component code:

1<aura:component implements="flexipage:availableForAllPageTypes" access="global" >
2    <lightning:workspaceAPI aura:id="workspace" />	
3    <aura:handler event="lightning:tabFocused" action="{! c.onTabFocused }"/> 
4</aura:component>

Controller code:

1({
2    onTabFocused : function(component, event, helper) {
3        console.log("Tab Focused"); 
4        var focusedTabId = event.getParam('currentTabId'); 
5            var workspaceAPI = component.find("workspace"); 
6        workspaceAPI.getTabInfo({
7            tabId : focusedTabId, 
8            callback : function(error, response){
9            	console.log(response);    
10            }
11        }); 
12    }
