How to navigate from Service to a Navigation Fragment using probably Pending Intent?

Question

I'm trying to open a fragment with args from my notification. Actually, in my case, I have Audio Player running with Foreground Service with Notification and now I want to navigate to my fragment for that specific Audio by passing Audio Id when a user clicks to the Notification.

You can open your activity with PendingIntent then open your fragment via handling the Intent inside of your activity.

or this answer from similar topic

NavDeepLinkBuilder:

val pendingIntent = NavDeepLinkBuilder(context)
                     .setComponentName(YourActivity::class.java)
                     .setGraph(R.navigation.your_nav_graph)
                     .setDestination(R.id.your_destination)
                     .setArguments(bundle)
                     .createPendingIntent()

//then

notificationBuilder.setContentIntent(pendingIntent)

this is clumsy when having much navigation. Didn't Navigation Architecture guys make any Utils for this? I mean handling Navigation with Intent easier. – Deflate

I used NavDeepLinkBuilder within my service and pass the service context and It didn't work can you tell how you used NavDeepLinkBuilder in your foreground service. – Teel

When targeting the new Android S, you have to use .createTaskStackBuilder() .getPendingIntent(0, FLAG_IMMUTABLE) instead of .createPendingIntent() otherwise your app will crash due to the new Pending Intent restrictions. – Arliearliene

How do you create a bundle to pass as an argument? How do you get data from notifications? – Beltran
