问题 This time I need your help regarding the use of android navigation components with deeplink. I have been following this documentation and the connection between fragment and deeplink is working fine. The problem comes in regards to the activity that is receiving the deeplink.

问题 I am trying to use androidx navigation with bottom navigation view.So when i put fragment with android:name = "androidx.navigation.fragment.NavHostFragment" in xml file it gives me an error. I guess that xml doesn't see this library or this Fragment Here is xml file : <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout

问题 I'm struggle building a Navigation, like on the image below, with the Android Navigation Component. I need a "Login Flow", check if the user is logged in and then navigate to the main part of the app (also clearing the backstack). The main part contains a BottomNavigationView with three tabs. But if I click on a settings icon on the toolbar, I also want to display a fullscreen SettingsFragment. Did I need two NavHostFragments with separate navigation graphs? If yes, how can I combine them and

问题 I'm using Jetpack Navigation for deeplinks. I've added android:launchMode="singleTask" to my Activity. Deeplink is redirected correctly if the app wasn't opened before.
