Hello all, in the tutorial for ionic 2 [ionic 2 tutorial](http://ionicframework.com/docs/v2/getting-started/tutorial) after clicking on an item the back button closes the app instead of going back to the list page I tried using platform `registerBackButtonAction` but it didn’t work. here is the code I tried ```auto import {Page, NavController, NavParams, Platform} from 'ionic-framework/ionic'; import {Inject} from 'angular2/core'; @Page({ templateUrl: 'build/pages/item-details/item-details.html' }) export class ItemDetailsPage { constructor(@Inject(NavController) nav, @Inject(NavParams) navParams, @Inject(Platform) platform) { this.nav = nav; // If we navigated to this page, we will have an item available as a nav param this.selectedItem = navParams.get('item'); this.platform = platform; console.log(this.platform); this.platform.registerBackButtonAction(function(){ },500); // this.platform.onHardwareBackButton(function(e){ // e.preventDefault(); // return true; // }); } } ``` ---

Hardware back button support is a feature we have not added yet. It’s on our road map ---

Is there any approximate timeline for this to be implemented in Ionic 2? At the moment, this makes using Ionic 2 for an Android app much less viable. ---

I think this should be the most basic feature and important. Android users are used to the back button, and will just stop using the app if it closes on pressing the back button. I am considering moving to ionic, and will not publish my app unless I am able to implement this. ---

This feature already exists in ionic V1. Since V2 is still beta, there’s still some features we need to work on. ---

Hi I’m a tad confused, why is there documentation for this: [http://ionicframework.com/docs/api/service/$ionicPlatform/#onHardwareBackButton](http://ionicframework.com/docs/api/service/%24ionicPlatform/#onHardwareBackButton) Are you saying this will not work yet? Thanks ---

@nebrekab So that doc that you have linked to is for Ionic V1. We’re talking about Ionic V2 ---

Or you could watch for the document event for back button and use it as you need, for example here’s mine from the `init()` method in the `app.ts` file inside `platform.ready().then(() => {...})`: ```auto // ------------ Double back button press to exit--------------- document.addEventListener('backbutton', () => { if (this.nav.canGoBack()) { this.nav.pop() return; } if(!this.backPressed) { this.backPressed = true window.plugins.toast.show('Presiona el boton atras de nuevo para cerrar', 'short', 'bottom') setTimeout(() => this.backPressed = false, 2000) return; } // this.platform.exitApp() navigator.app.exitApp() }, false); ``` ---

Ah! A subtle but important detail 🙂 Thanks for the reply. I’ll keep an eye on this, for the time being @Daveshirman fix worked. ---

His fix relies on alert while mine in toast notifications, both are valid options, it depends how you want the back button to work. ---

Hi, I have the same problem, i use ionic 2 beta 8 and here is my code: ``` this.platform.ready().then(() => { this.hideSplashScreen(); this.platform.registerBackButtonAction(function(event){ let nav=this.app.getComponent('nav'); if (nav.canGoBack()) {nav.pop();} else {this.confirmExitApp(nav);} },101); // Okay, so the platform is ready and our plugins are available. // Here you can do any higher level native things you might need. StatusBar.styleDefault(); }); ``` i tried on real device and the hardware back is disabled, it does nothing. Any help please. I googled a lot for any example of use of registerBackButtonAction in ionic 2 but no result ---

HI, I’m tring to override the backbutton with: ``` this.platform.registerBackButtonAction(this.goBack); goBack() { this.app.getRootNav().setRoot(Main); } ``` But I always get: `Uncaught TypeError: Cannot read property 'getRootNav' of undefined` Anyone has seen and solved this? Thanks ---

Maybe the app isn’t yet ready? Does it help to test the platform first? For the record, to override the back button I did the following, works fine for me: ``` onPageWillEnter() { this.platform.ready().then(() => { this.unregisterCustomBackActionFunction = this.platform.registerBackButtonAction(() => { // The special stuff I want to do and where I want to go }); }); } ``` and then later, before leaving my view, to set back the back action to her default behavior ``` this.unregisterCustomBackActionFunction(); ``` [Next page](https://forum.ionicframework.com/t/android-hardware-back-button-in-ionic/44522.md?page=2)
