Navigating navigation

The Navigation Architecture Component serves as a framework for navigating within your app. Ian covers how Navigation 2.2 and 2.3’s improvements in deep linking, APIs for returning a result, new support for testing Navigation, and integration with dynamic feature modules can make some common tasks and some tricky cases much easier to handle.

I'm facing issue in back transition when I implement shared transition in navigation component

[@technics6215]

Great. Can you now make SDK that can work without 50 new APIs, libraries and other stuff that will be deprecated and reinvented again after 3 years? Instead of making something useful at this moment I'm trying to learn another overcomplicated feature where I have to learn new rules and spells.

[@marlonlom]

This is the reason of navigating the 11 weeks of android 11 videos playlist :D

When support for saving backstack in bottom nav?

[@pxnx]

isn't that supported already?

[@plan2t]

I know that supported already, too

[@is0658]

@@plan2t they didn't? You could setupWithbottomNav but it wouldn't save fragment states and back stack. Ofc it's not hard to implement by yourself but I think it's time to make official support since it's a very common case..

[@RhexGomez]

Hopefully in the next vid you can discuss some best practices for Nav Arch with Dynamic Feature Module as well.

OMG so many good contents... loving it. :)

Error can't find current navigation node all the time!

Play at 1.25 speed OR 1.5.

[@devhypercoder6772]

2x speed....

Love these vids. Keep em comin!

I wish software developers would learn that just changing user interfaces doesn't mean improving user interfaces. My wife just got a new phone with version 11 and she can't figure out basic navigation on the infernal thing.

[@6june87]

Great video. By the way, are there any good material about using this framework on multi module projects? Is deep linking the PROPER way of handling this? And, it seems that navigating to the next fragment destroys the former fragment, and recreates it when pressing the back button. But, the viewModel initiated from the fragment seems to be alive. How long does this viewModel survive? Are there anything I can do to preserve data of the viewModel when my device runs out of memory(such as leaving it on the background for a long long time)?

[@pxnx]

neat talk Ian👍🏼

[@xpopcornx1747]

Like I said in the what's new in Jetpack video which nobody replied to, setting the result in Navigation is a huge mess. Rarely do you only want to set one property. Usually there is a bunch of variables you want to set when navigating back. Going by the example in the video you would need an observer for each of them and they have no guarantee about what order they will be executed in or at all. When returning from a page with information you obviously want to handle all of the data at the same time, not have an observer trigger for each.

[@DarekDeo]

You could create 1 data class to pass all the params in it. 1 observable for such result is fine.

[@odifek]

Just add all the data in a single parcelable data class

[@TekEffekt]

How would you pass back the result before Navigation? I’m not aware of extras that can be passed to a previous activity.

[@6june87]

Instead of using the new onActivityResult stuff, will using it via a livedata inside a shared global viewModel (the activity scope stuff) do something similar?

[@arnabkundu9410]

Does the navigation graph support the theme? If yes please tell me how can I enable it. I have multiple themes in my android application. But Now in navigation_graph, I am not getting theme changing opposition as we have in layout. Which should be a straight forward requirement from any client perspective. Thanks in advance. Arnab

Hi , anyone know how to show badge count on launcher icon of android app? I want to show message count like whatsapp, fb etc. But most of the devices doesn't support the library I got from github. Is there a reliable solution for this? Please help😕

[@indiemakerpodcast]

You have to create notification to show a batch without any library. I am using firebase push notifications and it automatically show batch on my app

[@deepuraju5272]

@@indiemakerpodcast while using notification, it shows the count of notifications. Can we customize that count? And when the notification is cleared or app remove from recents , this count will disappear. Did you get these issues?

[@6june87]

As far as I know, you can change the value via mCompatBuilder.setNumber(badgeInt). But from android oreo, if the user wipes the notification away, the badge of the launcher icon will vanish. I remember that from oreo, the kind of libraries you found started not to work.
