Tabbed View BackButtton navigation to main page

My app Home page is a normal card view, from home page users are redirected to Tabbed view page.
I am tried to enable backbutton but it’s just between the tabs it’s not coming from tabbed view to the Home Page.
I want on click of backbutton, to come out to the previous page of the page from where user was navigated to tabbed view .
I saw lot of post but nothing help me.
Please give some suggestion as soon as possible .
