[Android Showcase App] Push notification messages are not stored in the App

What
Very small issues but would be very nice to have them fixed for better user experience:

1. If the push notification (PN) is received when the Showcase App is running in background, after clicking on the notification, the home page of the showcase app is shown instead of the page with push messages. Switching to Push section of the App shows empty list of push notifications
2. PN is shown in the list of PN only if the current page is Push. After switching to a different section of App and back to Push section the list is empty again.
3. This is debatable but if the App is in the foreground, receiving push message should switch the current page to the Push section to show the list of push notification messages.
