Component used: Room auto migration Version used: 2.4.0-alpha02 Devices/Android versions reproduced on: Samsung xcover 4s / android 10

This problem occur when I have add a new column in a entity. Auto migration add this columns for the entity, but it is not pass to the entity where the object entity is embedded.

For make this error try to make auto migration when you add a new columns to a embedded entity.

This error not occur because I have no change my db version.

Reassigned to el...@google.com.

Yeah, it is our API issue. It is very unclear to developer that this will happen. Should we pass lifecycle as parameter?

IMO it is complicated issue/feature.

I see three possible use case scenarios:
1. Single actionBar/toolbar per activity. NavigationUI.setupWithNavController works fine.
2. Every fragment has its own toolbar. NavigationUI.setupWithNavController leaks views. And managing back arrow inside Toolbar is not necessary since it it not going to change.
3. Same toolbar used only for some fragments. Such case can occur when parent fragment has back stack with childFragmenManager.

I am not sure how to solve this best. If SDK user will pass fragmentLifecycle instead of viewLifeCycle then view is still be leaked for some time.

I decided not to use these methods at all because in my case (2nd) it is needed to update Toolbar only once - after Toolbar view create.

Use WeakReferences in NavigationUI

Avoid storing a strong reference to views
(such as a Toolbar within a Fragment) in
OnNavigatedListeners created by
NavigationUI.

NavigationUI makes an effort to clean up
after itself by removing the
OnNavigatedListener if one of its
WeakReferences was garbage collected.

Sorry I don't understand your request ! What do you means about that ?

Hi - I believe

comment #6

was a spam post, you can ignore it!

el...@google.com <el...@google.com> #9Jul 21, 2021 03:47PM

Sorry - one more follow up question - could you clarify what you mean by "This error not occur because I have no change my db version."? I'm working on reproducing the error and want to have the full backstory.

ba...@lamelcolor.ch <ba...@lamelcolor.ch> #10Jul 22, 2021 05:14AM

It is to say it's not a error by oversight.

el...@google.com <el...@google.com> #11Nov 4, 2021 10:54PM

Could you share the AutoMigration implementation that is getting generated? It should be located somewhere in the /build/generated/ap_generated_sources/ directory.

Resolving Auto-Migration error when a new column is added to an embedded Entity between versions.

This fix is particularly for the issue when the nullability of a column that is in an embedded entity is misinterpreted, generating an auto migration with missing default values.
