If the menu item is not meant to navigate, handle with super.onOptionsItemSelected. Traditionally you would use an intent-filter and associate a URL with the activity you want to open. The click listener code would look like this: Each navigate() call has a not very exciting default transition associated with it, as seen below: The default transition, as well as other attributes associated with the call, can be overridden by including a set of NavOptions.

Open res/navigation/mobile_navigation.xml, and click the Design tab. But in some cases you need to have different back stack history for each tab in bottom navigation view like Instagram app. When you're finished, you'll have a deep link widget.
