Handling Push Notifications when app is open

In Ionic 2, I’m trying to handle an event when the user is currently in the application so that I can pop an alert message and navigate to a different view. In my App constructor, I have the following code:

export class MyApp {
  private rootPage: any;

  constructor(private platform: Platform, private app: App, private push: Push) {
    if (UserService.isLoggedIn()) { this.rootPage = PickupPage; }
    else { this.rootPage = LoginPage; }

    console.log('We are here! We are here! We are here!');
    platform.ready().then(() => {
      // Okay, so the platform is ready and our plugins are available.
      // Here you can do any higher level native things you might need.
      console.log('Registering notifications handler');
      this.push.rx.notification().subscribe(msg => {
        alert(msg.title);
        console.log('Got something!');
        console.dir(msg);
      });
      StatusBar.styleDefault();
    });
  }
}

When I send a notification, on Android I get the notification coming up in the pull down bar on Android, but no console or alert inside the app and on iOS I just get nothing. No console message or alert and no notification in the notification center.

If you follow this tutorial, it will show alert popup when app is open to let use view or ignore the notification.

Thank you. Before I run through the tutorial, I’m trying to understand why the documentation for cloud push notifications flat out doesn’t work (http://docs.ionic.io/services/push/#handling-notifications). On that doc they don’t mention using the IonicNative Push object at all.

Edit

Okay. It seems like it does work, so long as I pass senderID in my cloudSettings config under the android object instead of just under the push object:

const cloudSettings: CloudSettings = {
  'core': { 'app_id': '***' },
  'push': {
    'sender_id': '***',
    'pluginConfig': {
      'ios': { 'badge': true, 'sound': true },
      'android': { 'senderID': '***', 'iconColor': '#d1b561' }
    }
  }
}

It also seems like cloudSettings is very sensitive and doesn’t like to pickup changes after the app is installed on a device.

Edit 2

Okay, I think I have a better understanding of things. So it seems that push notifications work only after I call push.register().then(...), which currently my app calls after login. When I add the following code to the app constructor, things seem to work:

this.push.register().then((token: PushToken) => {
  return this.push.saveToken(token)
});
```

Now the part that I'm not 100% sure on how to do things properly. When the user logs into my app, which is not driven by Ionic Auth, I want to save the token to my user session on the server. Would I use something like the following code:

```
this.push.register().then((token: PushToken) => {
  return this.push.saveToken(token)
}).then((token: PushToken) => {
  return this.userService.addDeviceToken(token);
});
```
Or is there a way to just access the already registered token?
