created issue #1

May 21, 2024 08:41AM

Component used: Navigation

Version used: 2.8.0-beta01

Devices/Android versions reproduced on: 24-33

Tested on emulators with android 24 and 33, and on a real device with android 24

To trigger system initiated process death, I set the background processes limit to 0

The following exception is thrown upon reopening the application: java.lang.IllegalStateException: Restoring the Navigation back stack failed: destination 161177858 cannot be found from the current destination ComposeNavGraph(0x0) startDestination={Destination(0x8431a13) route=com.myk00l.test.B}

            NavHost(navController=navController, startDestination = B) {

I've tested the app's behaviour using typed navigation. I've also discovered that it crashes after the death process when reopening the app. I tested this on API 33 and API 30 emulators.

You can find the source code at the following URL: https://github.com/hellosagar/PlayInfo/

To replicate the issue:

Clone the repository
Run the app
It will display a screen with 3 EditText fields; enter random values in each field
Simulate a system crash
Open the app, and it will crash with the following stack trace.

I've also created an issue with a video attached - https://github.com/hellosagar/PlayInfo/issues/14

Yes can also reproduce in my app! App in background, get process killed, reopen it and it crashes.

Lib version: 2.8.0-beta02
Os version: all
Language: all

Please fix it quickly as typed navigation is really something needed. Thanks guys you rock <3

Fix crash when resume after process death

RestoreState crashes when resuming after process death because the destination ID which is based on serializer hashcode() is different after process death.

Update the hash algorithm that safe args

destination.id is based on.

Test: manual test by killing process in emulator
Test: ./gradlew navigation:navigation-common:cC
Test: ./graldew navigation:navigation-runtime:cC
Bug: 341801005
Relnote: "Fixed crash from restore state when resuming the app after process death."

Marked as fixed.

Fixed internally and will be available in navigation-2.8.0-rc01

jo...@hella.info <jo...@hella.info> #10Jun 26, 2024 12:09AM

I have a lot of code like this:
```
val entry by navController.currentBackStackEntryAsState()
when (entry?.destination?.id) {
ScreenA.serializer().hashCode() -> R.string.example
...
}
```
Just to describe the current screen in a top bar. I used to do this with the `route` instead of the `id, and i have searched for quite a while for an alternative with type safe navigation and found this possibility.
I think this commit will break my code, right? And if so, what would be the correct way to determine the current type safe navigation route i am on?

cl...@google.com <cl...@google.com> #11Jun 26, 2024 01:03AM

comment#10 you'll want to use the hasRoute api. If you have further questions, please file a separate bug.

I am using version 2.8.0 and still get this error when the app has been in the background for a few hours when I reopen it. There is a hint in the previous comment that there are more parts to address. Is there anything more planned regarding this issue?

Please file a separate bug with a minimal sample project that reproduces your issue.
