created issue #1

Feb 3, 2019 01:59AM

Component used: Navigation
Version used: 1.0.0-alpha11
Devices/Android versions reproduced on: Nexus 5X API 27

I've implemented conditional navigation for my login flow as described in this SO post:

https://stackoverflow.com/questions/51582674/navigation-architecture-component-login-screen

Now everything appears to be working, however after being navigated to the login screen and successfully logging in then navigating back to the main screen, on rotation the app crashes with the error: "java.lang.IllegalStateException: unknown destination during restore".

I've created a SO post containing the full error and navgraph for my project:

https://stackoverflow.com/q/54496008/7648952

I've also reproduced the error in this sample app:

For a bit of further information it appears this crash started to occur in version 1.0.0-alpha08.

I still get this error using the lastest 1.0.0 release :

implementation 'android.arch.navigation:navigation-fragment-ktx:1.0.0'
implementation "android.arch.navigation:navigation-ui-ktx:1.0.0"

I'm using nested graphs.
