I'm getting the same error today

Any chance you could provide a way to repro this crash?

Andrey, could you verify if this is the same root cause as

I have a way to repro inside my app but not yet fully back to try to extract something I can share.
I just quickly tested latest SNAPSHOT (10683443) and now the error is different and requires a lot more scrolls to trigger.

And for my case, this is an 1.6 A3 issue, reverting to 1.6 A2 (And M3 to 1.2 A4) does fix this at 100%
mn...@google.com
I just quickly tested latest SNAPSHOT (10683443) and now the error is different and requires a lot more scrolls to trigger.
Thanks for verifying. The snapshot above contains our fix for placement that affected lookahead. Given that the issue is a lot more difficult to trigger, it's likely the result of the fix. The new stacktrace seems like a different issue.
Andrey, could you take a look at the stacktrace in
ut...@gmail.com
The original stacktrace which has "forceMeasureTheSubtree" in it is the one fixed by aosp/2698053 which should be a part of the next alpha. However the new one "LayoutNode should be attached to an owner" is something new and I don't have immediate ideas what it can be related to. We will need a way to reproduce it, maybe you can try to come up with a sample project?
ed...@gmail.com
Since it will still crash in A4 for my app, I'm reverting to A2 and a little out of delay so lack time this week to try to extract a repro that will probably be complicated as only crashing in a specific screen.
I can still add some logs / test things if you have idea to gain time on this. (Like what I could remove from that screen to pinpoint,...)
Description
Jetpack Compose component used:`semantics`
Android Studio Build:Android Studio Flamingo | 2022.2.1 Patch 2
Kotlin version: 1.8.21
Thank you so much for the travesalIndex/traversalGroup release! It has mostly worked as expected. The one issue I am seeing is when the parent has semantics(mergeDescendants = true) {}. I made an example:
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
TraveralTestTheme {
TraversalExample(
modifier = Modifier
.semantics(mergeDescendants = true) { }
.background(color = Color.Gray)
.fillMaxSize()
)
}
}
}
}
@Composable
fun TraversalExample(
modifier: Modifier = Modifier,
) {
Row(
horizontalArrangement = Arrangement.Center,
verticalAlignment = Alignment.CenterVertically,
modifier = modifier.semantics { isTraversalGroup = true },
){
Column {
Text(
text = "I should be announced first",
modifier = Modifier
.padding(16.dp)
.semantics { traversalIndex = 1f },
)
Text(
text = "I should be announced third",
modifier = Modifier
.padding(16.dp)
.semantics { traversalIndex = 3f },
)
}
Text(
text = "I should be announced second",
modifier = Modifier
.padding(16.dp)
.semantics { traversalIndex = 2f },
)
}
}
The announcement order is: 1,3,2.
The announced string is: "I should be announced first, I should be announced third, I should be announced second"
