Jetpack Navigation Deep Link with wrong ActionBar button

Question

When I open my application from the launcher icon, all the Navigation and ActionBar button works fine. But when I access the application from an explicit deep link, my ActionBar gets confused.

My main navigation is:

-> [TaskListFragment] -> [TaskDetailFragment]

When opening by the launcher icon, the back button shows correctly:

In my app, you can create an alarm for each task, so when the alarm rings and the user clicks on the notification, the flow is:

-> [TaskDetailFragment]

Then, it shows the wrong button: Clicking in the drawer icon, it returns to [TaskListFragment]. The behavior is correct, but the ActionBar icon is not.

This is how I'm creating the deep link:

NavDeepLinkBuilder(context)
            .setGraph(R.navigation.nav_graph)
            .setDestination(R.id.taskDetailFragment)
            .setArguments(arguments)
            .createPendingIntent()

Here is the complete code on GitHub.

MainActivity with all the Navigation boilerplate.

And my Navigation Graph.

I also tried several base implementation, such as Google's Sunflower and Architecture Components Sample without success.

Answer 1

I opened an Issue Tracker once I thought this was a bug in the library.

Actually the issue is that I'm using a ActionBarDrawerToggle to do a custom Drawer animation and based on the developer that replied to the issue:

"[...] the Navigation documentation suggests not using ActionBarDrawerToggle at all, as transitions are handled for you"

And in the Navigation docs:

Note: When using NavigationUI, the top app bar helpers automatically transition between the drawer icon and the Up icon as the current destination changes. You don't need to use ActionBarDrawerToggle.

Once I need the ActionBarDrawerToggle for the custom animation, I can't remove it. To fix the issue, I need to call my Drawer setup first with the ActionBarDrawerToggle definition and then call the Navigation setup methods, like NavigationUI.setupActionBarWithNavController().

TL;DR

If you are using ActionBarDrawerToggle with Jetpack Navigation make sure that you set the ActionBarDrawerToggle before call the Navigation methods.
