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        }).then(function(response) {
9            console.log(response);
10        });
