Can you attach a sample project that reproduces your issue?

I'm experiencing this issue in a commercial non-open source project so I'd have to provide extracted code fragments. The menu file for instance looks similar to this:
<menu>
<item
android:id="@+id/destination_one" />
<item
android:id="@+id/destination_two" />
<item
android:id="@+id/destination_three" />
<item
android:id="@+id/destination_four" />
</menu>
The menu item ids match the top level destination ids as for instance destination_one as required by the NavigationUI library.
The xml layout file of the main activity (there is only one activity) looks pretty much like this:
<androidx.coordinatorlayout.widget.CoordinatorLayout>
<androidx.constraintlayout.widget.ConstraintLayout>
<androidx.fragment.app.FragmentContainerView
android:id="@+id/navigation_host_fragment"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="0dp"
app:defaultNavHost="true"
app:layout_constraintBottom_toTopOf="@id/bottom_navigation"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:navGraph="@navigation/main_navigation" />
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="@+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@id/navigation_host_fragment"
app:menu="@menu/main_menu" />
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
The main_navigation
is the first navigation graph I posted in the original post. The behavior I described above only affects the first bottomNavigation item which corresponds to the top level navGraph's startDestination.

Yeah, what we're looking for is a full project (i.e., take a brand new project in Android Studio, put your few bits of code in, and make sure your problem reproduces) as there are a lot of little pieces that can make a difference here.
jb...@google.com <jb...@google.com> #5
Of course the logic of my project is more sophisticated but this reproduces the issue quite well. If you click the first BottomNavigation item N times you need N+1 system back navigation triggers to leave the app.

So first, we plan to get rid of these APIs in the future. The only behavior for NavigationUI will be to always save and restore the state of the back stack. Luckily, NavigationUI is purposely built only on publicly available APIs so you could always copy our code and make your custom adjustments for whatever your desired behavior is.
The source of the bug is
We need to add a fix to ensure we take into account the proper destination on our side, but as I mentioned those APIs will go away in the future. So if you wanted to proactively create your own API, you could make your API navigate directly to the start destination instead of the graph. That would allow you to not wait on our release and ensure you always have your desired behavior going forward.
jb...@google.com <jb...@google.com> #7
Thanks a lot for your help! I basically removed the first embedded graph by moving the code directly into the topmost navGraph and as you said, navigate directly to the start destination. As far as I can tell, it seems to work now.

Fix BottomNavView launchSingleTop with NavGraph
NavController previously did not apply launchSingleTop when user repeatedly navigates to the starting destination of a Menu when this starting destination is a NavGraph. This results in the destination being added mulitple times to backstack.
Now NavController checks if the destination is a NavGraph and if so, adds all destinations from the node to its final startDestination (i.e. nested nav graphs) to singleTop.
NavController backstack and Navigator backstacks entries are replaced accordingly upon singleTop navigations.
Test: ./gradlew navigation:navigation-runtime:cC
Bug: 253256629
Relnote: singleTop now works with NavGraph such that if the top destination of the backstack is a NavGraph's startDestination, all destinations starting from original destination to its startDestination will only be added to the top of the backstack once.

Hi, I added a sample project.
I also confirm that by manually importing
kotlinx-serialization-json (version 1.7.3 as an example), the compilation ends successfully.
in this project i am using 2.8.4, but it still reproduces.
The problem is definitely on the overload of the setStartDestination method which uses the generic T method, instead of the specific int

Fix wrong setStartDestination overload in Java

Fix wrong setStartDestination overload in Java
Java compiler links to the wrong NavGraph.setStartDestination overload which takes a `startDestination: T` instead of the correct `startDestination: Int`.
The overload that takes `T` is part of the Navigation SafeArgs features for kotlin users, so we hide this overload from Java sources with @JvmSynthetic.
This annotation is binary compatible. https://kotlinlang.org/api/core/kotlin-stdlib/kotlin.jvm/-jvm-synthetic/
Test: manual testing
Bug: 364634035
Relnote: "The kotlin-specific NavGraph.setStartDestination overload for type safety is hidden from Java sources."

Fixed and available in navigation-2.9.0-alpha04
da...@gmail.com <da...@gmail.com> #17
I have tried this fix by using navigation-2.9.0-alpha03
and removed the temp fix of implementation 'org.jetbrains.kotlinx:kotlinx-serialization-json:1.7.3'
however the same error has returned during build:
"class file for kotlinx.serialization.KSerializer not found"
The build is successful when retaining implementation 'org.jetbrains.kotlinx:kotlinx-serialization-json:1.7.3'
Is this expected, or is there perhaps something else I'm not doing?

Description
Version used: 2.8.0
Devices/Android versions reproduced on: Android 11
Previous working version: 2.7.7
Using Navigation 2.7.7 all works fine but when updating to 2.8.0 I get "error: cannot access KSerializer" ("class file for kotlinx.serialization.KSerializer not found") at this line:
- navGraph.(HERE IS THE MARKED POINT)setStartDestination(R.id.nav_permissions)
during "Task :app:compileDebugJavaWithJavac".
This piece of code placed in a MainActivity.onCreate() method:
- NavGraph navGraph = navController.getGraph();
- navGraph.setStartDestination(R.id.nav_permissions)
Those are my TOML libraries versions used in this project:
annotation = "1.8.2"
appcompat = "1.7.0"
constraintlayout = "2.1.4"
flexbox = "3.0.0"
gradle_plugin = "8.6.0"
kotlin = "1.9.24"
livedata = "2.8.5"
material = "1.12.0"
navigation = "2.8.0" (<-- returning to 2.7.7 solves this issue)
preference = "1.2.1"
sdk_compile = "34"
sdk_target = "33"
volley = "1.2.1"
Unfortunately the project is very big and I'm unable to cleanup to create a simple sample project for replicate this error.
I hope it would be enough those info.....
