Minimize android app from initial screen not working

[vishnuc]

I have two scenes like below

render() {
    return <Router> 
      <Scene key="root">
 	      <Scene key="Feed" component={Feed}   initial={true}  hideNavBar={true} />
 	      <Scene key="Refer"   headerTitle={Refer} gesturesEnabled={true} hideNavBar={true} component={Refer}   />
        </Scene>
    </Router>;
  }
}

When I am in Refer page and When I press back button , Its working fine and navigating to Feed page , I want app to minimize if I press back again in Feed page , but its not working
