created issue #1

Feb 16, 2023 07:24AM

Jetpack Compose version: 1.4.0 alpha X (User is not very clear when it started)

Jetpack Compose component(s) used: Most of them

Android Studio Build: Girafe

Kotlin version: 1.8.10

Steps to Reproduce or Code Sample to Reproduce:

I don't know how to reproduce, I'm pretty sure he changed some settings on the device but can't find anything in Compose code to figure out what.

That user on his device Moto G Power (2021) have lost all velocity in scrolling / fling actions.
It touches all lazyRow/Column with or without snapFling.

See attached video.

He's the only one to report that, so I suppose this is something similar to compose animation respecting the Android dev settings about animation scale. But I can't figure out to what setting / parameter this could be related.

Status: Assigned (reopened)

A couple of questions:

1. Have you saw crash in real device or only in simulators?
2. Do you use dynamic feature for language ID?

to...@gmail.com <to...@gmail.com> #3Feb 17, 2023 11:06AM

Tested on Android 12 Emulator with custom executor, but cannot repro this issue.

Status: Won't Fix (Not Reproducible)

Second crash in the description is from a real device. Experienced it myself on two different Xiaomi phones, plus lots of crashes from users in the Google Play console.
Dynamic features are not used in the application.

As a wild guess, I have downgraded build tools from 31.0.0 to 30.0.3, compileSdk from 31 to 30, and moved all work with Language ID to the service in a separate process (just to be sure that crash can kill secondary process instead of main). This combination is in beta for 2 days by now and I don't see any SIGSEGV crashes.

to...@gmail.com <to...@gmail.com> #5Feb 17, 2023 11:30AM

Hmm, I feel the crash might be something related to separate/secondary process.

I also changed compileSdk and targetSDK to 31 but still cannot repro this issue.

On the contrary, there was no separate process before, when crashes started.

In the new build (with the aforementioned changes) I can see SIGSEGV crash, but only one instead of dozens and it has a bit different backtrace:

signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)
liblanguage_id_jni.so (offset 0x11e000)

FYI, ML Kit launched a new language ID SDK in the latest release, which uses a new language ID model. https://developers.google.com/ml-kit/release-notes#august_11_2021

Could you try the new SDK version(17.0.0) to check if you can still repro this native crash? Thanks!

jo...@google.com <jo...@google.com> #8Feb 17, 2023 12:35PM

Thank you, I'll try it and check.

Hello. I have similar experience.

I'm using mlkit-language 16.1.1
I didnot meet this error until using AGP 4.2
I can get this error since using AGP 7.0
This error raised on Release build only(minimized by R8)
This error raised without obfuscation.

Also I found there is a post which presents same issue on stackoverflow.

Could you also check if this is reproducible on 17.0.0 or 17.0.1? If yes, could you attach the full log that I can take a look? Thanks!

- You can see R8 debug mode on build log : https://scans.gradle.com/s/c6h5hy2nxod4u/console-log#L95

Also, I pushed to update MLKit Language Id version 17.0.1 on mlkit17_agp7 branch And here is gradle build scan

https://scans.gradle.com/s/ytaa2kkbp5vc4
- Here is version of com.google.mlkit:language-id

And here is crash log after apply 17.0.1
You can see that BuildId of liblanguage_id_l2c_jni.so was changed from 859ec0ec2000a39e6ae8ed42e1704f46 to be6e59455cc10135330c93acdebfc121

Hi,

Looks like we figured out the root cause in b/203573699

For temporary workarounds for the existing SDKs, you need to add this rule

-keep class com.google.mlkit.nl.languageid.internal.LanguageIdentificationJni { *; }

for language-id 16.1.1, and add this rule

-keep class com.google.mlkit.nl.languageid.internal.ThickLanguageIdentifier { *; }

for version language-id 17.0.0+ for the newer model.

We'll fix this issue in the upcoming release so that you'll not need these workarounds in the future release.

Thanks a lot for reporting this issue!

le...@google.com <le...@google.com> #16Feb 22, 2023 12:55PM

Added workarounds in Known issues section in public docs.

So I guess we can thank the nice Canadian user who took a lot of time on this. (And me at the same time maybe)

I mostly reversed the pageToken for the snapshot list and did the dichotomy search.

The PR causing issue on his device (and his wife that have the exact same device) is https://android-review.googlesource.com/c/platform/frameworks/support/+/2323493 Sad no one was able to remember that one since it's clearly stated as change to velocity tracker.

As a reminder he have no issue on any other non Compose app on his device, so the platform way works there.

le...@google.com <le...@google.com> #19Feb 23, 2023 10:29AM

Hey, the change you linked was published on 1.4.0-alpha04 and you previously mentioned that the issue was between alpha02 and alpha03?

That change didn't raise any signals internally and externally (apart from your user's device) since it is a parity change with platform, but since you're saying they didn't have issues with other apps I'm going to try and get a hold of a similar device so I can try to reproduce the issue. In the meantime could you give me a barebones structure for one of the screens where the issue is happening so I can create a sample app that is close enough to yours to test when I get the device?

Thanks.

to...@gmail.com <to...@gmail.com> #20Feb 23, 2023 10:53AM

Yes the user mixed the APKs during the first tests as I sent him all of them at once.

Improved the process later with version display so he could not repeat the mistake.

I'm joining Layout inspector export (From Girafe A6) for one of the screen should give you everything and details.

The user report the exact same behavior on his wife phone (same device) with no other issues in any other apps.

Since he already passed a couple of hours on this, he agreed to run other test builds if you need to logs things if you know what. I'd really like this to be fixed in final 1.4 and stop chasing bugs and alphas. 1 year of doing this was exhausting I'd like some rest now that most of the other issues are fixed :)

Bump, RC is tagged :(

As I said I can do whatever debugging is necessary with the help of the user and would appreciate a way to move forward if you can't get the device.

to...@gmail.com <to...@gmail.com> #22Mar 9, 2023 09:02AM

Really love the communication and the feeling that external devs are important and partners as all the communications says ;)

Can you check https://android-review.googlesource.com/c/platform/frameworks/support/+/2475105 and see if that change would also be applied to the velocity tracker here?

If not can you check if that could be the cause, since from the bugs it's rare and touched the same kind of devices.

le...@google.com <le...@google.com> #23Mar 10, 2023 10:43AM

Hi, we still don't have updates on this, still trying to get a hold of a similar device. Since this only happens with a single device model it's a bit tricky to reproduce. I talked with the team internally and it seems that any sort of additional debugging to actually find the issue would need to be done on the device.

The code change in https://android-review.googlesource.com/c/platform/frameworks/support/+/2475105 is used by the pointer input system that in the end generates events that will be added to VelocityTracker, so they might change the events that will be added to the tracker.

If not can you check if that could be the cause, since from the bugs it's rare and touched the same kind of devices.

Maybe the device is generating bad MotionEvents and that in turn can cause the scroll to not get the proper events to generate an accurate fling, but without a device to test it it would hard for us to know.

In the meantime, we can take a look at both the events that the pointer input system receives and the MotionEvents generated by the specific device vs a device where it works properly? Maybe that could give an insight on what type of events Compose is receiving.

For looking into the pointer input system events generated to a given composable you can do something like:

    LazyColumn(modifier = Modifier.pointerInput(Unit) {
       coroutineScope {
        awaitEachGesture {
            while (isActive){
                awaitPointerEvent(pass = PointerEventPass.Initial).changes.forEach{
                    println("$it")
                }
            }
        }
       }
    })

For looking into MotionEvents you can log inside dispatchTouchEvent of your root activity.

Let us know what you find out.

Thanks.

Thanks, since I don't really know what I'm looking for I attached the logs from the user.

And a simple fling from my device (P6 Pro):

So after a lot of pain due to java.lang.NoSuchMethodError: No static method AnimatedContent(Ljava/lang/Object;Landroidx/compose/ui/Modifier;Lkotlin/jvm/functions/Function1;Landroidx/compose/ui/Alignment;Lkotlin/jvm/functions/Function4;Landroidx/compose/runtime/Composer;II)V in class Landroidx/compose/animation/AnimatedContentKt; in 1.5 I made him test snapshot 9725230 and the issue is still present.

Attached same logs in case that other PR did change the events received.

Bump?

le...@google.com <le...@google.com> #28Apr 6, 2023 01:55PM

Hey, I took some time looking into the logs, the classification is not really a problem, even though it's different. In my own device the classification is None and I don't see the problem.

Something that caught my attention was that in one of the log files you sent I see a number of Cancel events in the middle of Move events. This might indicate that Motorola's implementation of the Root View is somehow canceling the move events. Any cancelation in the motion events will cause the inner draggable to emit a velocity of 0 to the fling system, which might explain the hiccups your user is seeing.

I'm assuming these events come from the Root Activity in your app and no compose hierarchy is outside of it, this is important because these events will have come straight from the system instead of another compose hierarchy that might send cancel events. If this assumption is correct and you'd like to confirm you might add markers to the logs to indicate the start/end of the flings. You can do this from a NestedScrollConnection around one of your lists. You can emit a log onPreScroll and another onPostFling, this should capture the whole range of a drag+fling movement. If in the middle of the movement you see a MotionEvent action cancel, then this indicates that the system is canceling the movement. The ideal log should be a down event followed by a series of move events and finally an up event.

If this is a device issue, you may ask the user if there has been a system update which might explain why they've only started seeing this recently.

In any case, let us know what you find out. Thanks.

to...@gmail.com <to...@gmail.com> #29Apr 6, 2023 02:57PM

If this is a device issue, you may ask the user if there has been a system update which might explain why they've only started seeing this recently.

That's the first thing I asked him when he report the issue, before doing all the investigation.

This is not hardware as 2 devices does this He have 0 issues on any other applications (But not sure he have other recent compose apps). Reverting to the commit just before that patch does fix the issue for those devices.

The app activity is just a single setContent{} there's no views or anything else and yes I added the logs there as requested.

I can add more logs to see the start and end but I suppose this would just confirm the cancel events, not the source if it happens outside of Compose.

Is there any change to have a workaround or something I can as an hack like filtering / rewriting the wrong events? I suppose a call or a system dialog during a drag would trigger a valid cancel event too?

Hi, we're still waiting for the device. In the meantime, we're addressing some fixes in our velocity tracker that may help you as well. We received a report of a case similar to yours (a single device, this time a watch). They reported that using our fix resolved the problem for them, so it might solve for your as well.

The fix is still being tested, so it hasn't landed as the default behavior, but you can still access it by flipping this flag to true: https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/ui/ui/src/commonMain/kotlin/androidx/compose/ui/input/pointer/util/VelocityTracker.kt;l=688?q=VelocityTracker.kt

Hi, we just received the device. Could you provide an apk with a version of the app where the issue is happening? I tried using a simple LazyColum/LazyGrid, but they scroll fine. Thanks!

to...@gmail.com <to...@gmail.com> #34Jun 2, 2023 11:21AM

Can't build an APK right now you can install from https://play.google.com/store/apps/details?id=app.symfonik.music.player else I'll build tonight.

le...@google.com <le...@google.com> #35Jun 5, 2023 09:35AM

Hi, thanks I was able to reproduce the issue using your PlayStore version. Using a simple LazyColum/LazyGrid doesn't have the same problem, so this means that there's some specific setup on your screen that may be causing this issue. Is there anything else you can tell us about those screens? From using your app it seems you have some pointer input interactions in the list items? In any case, I'll try to check if there's something different about this device's motion events.

to...@gmail.com <to...@gmail.com> #36Jun 5, 2023 10:33AM

https://issuetracker.google.com/issues/269487059#comment20 have a complete layout inspector export that should show most of the things no ?

From the user report this touches everything that is scrollable.

The only thing I can think of that touches most of the screens would be the nestedScroll. (The container may change)

    Box(
        modifier = Modifier
            .fillMaxSize()
            .nestedScroll(topButtonBarState.nestedScrollConnection),
    )


    val nestedScrollConnection = remember<NestedScrollConnection> {
        object : NestedScrollConnection {
            override fun onPreScroll(available: Offset, source: NestedScrollSource): Offset {
                val delta = available.y
                val newOffset = topBarOffsetPx.floatValue + delta
                topBarOffsetPx.floatValue = newOffset.coerceIn(-topBarScrollDistancePx, 0f)
                return Offset.Zero
            }
        }
    }

Ho and yes most of the images can be long press to drag and drop:

So just got another strange report today tied to the drag and drop posted above. Maybe it's linked as it seems there's also some wrong cancel events.

2023-06-06 01:26:42.504 Verbose/Logger: Information: XQ-CQ62/XQ-CQ62/33/13/XQ-CQ62/Sony/ 2023-06-06 01:26:42.505 Verbose/Logger: Information: 5.4.0 (1008[arm64-v8a,armeabi-v7a,armeabi]) - DisplayMetrics{density=2.8125, width=1080, height=2452, scaledDensity=2.8125, xdpi=449.704, ydpi=450.76} - FS:1.0 - AS:1.0

See video but the drag is randomly cancelled.

Hum still no 1.6 release. Is there an ETA? (Like for next release day in 15) or is there some blocker due to U support and it will be longer?

I'd like to avoid playing with snapshots again to avoid too many side effects, but I'd still like to move on with the test :(

Hi, not wanting to hijack this bugreport, but I have something similar going on an Android 7.1.1 device.
From my logging with NestedScrollConnection, I see that in my case the onPreFling almost always has a zero available Velocity. If anybody has any idea on what could cause this?

to...@gmail.com <to...@gmail.com> #40Jun 22, 2023 04:06PM

So the first issue seems fixed in 1.6 A1 and VelocityTrackerAddPointsFix set to true just after SetContent.

Is there known issues with this for the option to be disabled by default even if it's announced to be forced in RC?

Waiting for feedback about the second drag and drop issue.

to...@gmail.com <to...@gmail.com> #41Jun 22, 2023 06:04PM

And got the confirmation that it fixes the other user drag and drop bug too.

Would love to have details about known issue / reasons it's off in A1 before putting that to open beta.

le...@google.com <le...@google.com> #42Jun 23, 2023 08:19AM

Hey, I'm glad it fixes your issues. We will be conducting some experiments with the fix before landing it in full in the upcoming releases, that's why it's still turned off by default. The idea is to better understand the uses of our velocity tracker for further improvements. The final goal is that the flag will be removed and the final behavior will be with the fix.

to...@gmail.com <to...@gmail.com> #43Jun 23, 2023 08:22AM

So there's no currently known blockers, just lack of tests and I can try in open beta and report back here? The open beta on that app is limited to 4K users but if I fix 2 users and break 3998 it won't be fun :)

le...@google.com <le...@google.com> #44Jun 23, 2023 08:29AM

Aw, we do have tests in place. For context, this is a fix to the existing behavior that should approximate Compose velocities to the velocity calculation used by the platform. You should be safe and we will do a similar experiment on our side (that's why we're not turning it to true by default, we'd like to be extra sure the behavior is what we wanted it do be), but if you want to be even safer and you have the means I'd suggest you control the switching on/off of the flag using some remote config.

to...@gmail.com <to...@gmail.com> #45Jun 23, 2023 08:34AM

That app have some targets providers that are full FOSS and their users don't like firebase/google trackers and want full offline functions so no remote config for that one.

I can add a temporary setting for the users to disable the feature if it's broken for them. Does changing the value instantly toggle the behavior or should I restart the app?

le...@google.com <le...@google.com> #46Jun 23, 2023 08:35AM

It should be instant, since it's backed by state it will cause a recomposition.

to...@gmail.com <to...@gmail.com> #47Jun 23, 2023 08:38AM

Ok perfect I'll do that then. Should we keep this issue opened and I report related issues here (if some occurs) or close and open new ones if needed?

le...@google.com <le...@google.com> #48Jun 23, 2023 08:39AM

Yeah, I'll keep it open at least until we land the fix in full, and even then if your issue isn't fully fixed I'll keep it open :)

Hi wbervoets@gmail.com, could you open up another ticket so we can continue this conversation there? I'd need to go through your setup to better understand how your hierarchy looks like to say if this actually the same issue or something different.

Ok so it seems the new pointer fix does have side effects on fling. The native Compose one or the Chris banes Snapper.

I'm yet to build a repro and fully understand what's going on but on a LazyColumn with a small width and val flingBehavior = rememberSnapperFlingBehavior(listState, snapOffsetForItem = SnapOffsets.Start) (Snapper version) then in some cases when you fling and end the fling gesture outside of the column the fling goes crazy.

When it happens typically, you fling up the lazycolumn start to scroll down as expected then quickly scroll up ultra fast up to the first item of the list.

Disabling VelocityTrackerAddPointsFix restore proper behavior. This only occurs when the fling ends outside of the box of the column so no issue on full screen lazy column.

Ok so no there other things broken with that option enabled :(

See attached videos OK is with that option off and NOK is with the option ON. As you can see the flings trigger erratic NestedScrollConnection data.

For that screen the NestedScrollConnection is :

internal class EnterAlwaysNestedScrollConnection(
    private val offsetY: MutableState<Int>,
    private val toolbarState: CollapsingToolbarState,
    private val flingBehavior: FlingBehavior,
) : NestedScrollConnection {
    private val scrollDelegate = ScrollDelegate(offsetY)

    override fun onPreScroll(available: Offset, source: NestedScrollSource): Offset {
        val dy = available.y

        val toolbar = toolbarState.height.toFloat()
        val offset = offsetY.value.toFloat()

        val consume = if (dy < 0) {
            val toolbarConsumption = toolbarState.dispatchRawDelta(dy)
            val remaining = dy - toolbarConsumption
            val offsetConsumption = remaining.coerceAtLeast(-toolbar - offset)
            scrollDelegate.doScroll(offsetConsumption)

            toolbarConsumption + offsetConsumption
        } else {
            val offsetConsumption = dy.coerceAtMost(-offset)
            scrollDelegate.doScroll(offsetConsumption)
            val toolbarConsumption = toolbarState.dispatchRawDelta(dy - offsetConsumption)
            offsetConsumption + toolbarConsumption
        }

        return Offset(0f, consume)
    }

    override suspend fun onPreFling(available: Velocity): Velocity {
        val left = if (available.y > 0) {
            toolbarState.fling(flingBehavior, available.y)
        } else {
            available.y
        }

        return Velocity(x = 0f, y = available.y - left)
    }
}

Thanks to Scaleway I've lost a tons of time in urgent servers migrations that I need to recover so won't be able to build a smaller repro project for now. But can provide details or anything useful to help fix those as the cure seems worse than the decease.

Thanks for reporting this, I'll go back to trying to get a fix for the issue.

Were you able to reproduce? I might be able to schedule a couple of hours on trying to repro end of next week if not.

Hey, yeah, I have a possible fix, trying to get it landed before the next release. Thanks!

to...@gmail.com <to...@gmail.com> #57Jul 6, 2023 03:15PM

Ok thanks.

On my side I'll go in prod next week with 1.6 A1 and VelocityTrackerAddPointsFix on, but auto disabled on the bugged parts of the app and that user can opt out.

This might brings more reports, but so far after a week and +/- 2K users having that version active in the beta no other issues reported.

Use previous event when no historical is available in VT.

The calculation was redundant when adding events to the VT when there was no historical data. If there's no historical delta, we should use the previous event data to calculate the delta and add it to the reference offset.

So quickly tested alpha 02 and #52 is fixed.

But #53 is still completely broken.

The workaround I use on that screen:


            DisposableEffect(Unit) {
                val saved = VelocityTrackerAddPointsFix
                VelocityTrackerAddPointsFix = false
                onDispose {
                    VelocityTrackerAddPointsFix = saved
                }
            }

The good news is that I did not get any other report of any other issue. So if we can figure out #53 I guess this will be good.

le...@google.com <le...@google.com> #60Jul 30, 2023 06:05PM

That's odd, the fix I landed on #58 was addressed because of your report #53, the normal flings on a list stopped working properly when VelocityTrackerAddPointsFix was true. With #58 this should be fixed + the original. I'll need to check it again in this case.

to...@gmail.com <to...@gmail.com> #61Jul 30, 2023 06:11PM

The flings are the #52 and are fixed.

The #53 is about values sent to NestedScrollConnection

I'm on kid duty this week but can try to debug / log stuff in my app if you can't repro. I did 0 checks on that part so no idea if the issue is the onPreFling or onPreScroll

Just tell me what you need.

to...@gmail.com <to...@gmail.com> #62Aug 4, 2023 03:24PM

Some quick logs:

As you can see there's some inversion in the onPreScroll values and a complete reduce of the values too.

It happens after the onPreFling

That code is a quoted earlier:

    override suspend fun onPreFling(available: Velocity): Velocity {
        val left = if (available.y > 0) {
            toolbarState.fling(flingBehavior, available.y)
        } else {
            // If velocity < 0, the main content should have a remaining scroll space
            // so the scroll resumes to the onPreScroll(..., Fling) phase. Hence we do
            // not need to process it at onPostFling() manually.
            available.y
        }

        return Velocity(x = 0f, y = available.y - left)
    }

The state fling function is :

    suspend fun fling(flingBehavior: FlingBehavior, velocity: Float): Float {
        var left = velocity
        scroll {
            with(flingBehavior) {
                left = performFling(left)
            }
        }

        return left
    }

I do not change fling or snap in that screen so it's probably using DefaultFlingBehavior, not sure what is happening there but I hope you do :)

Fix VelocityTracker test flakiness: VelocityTrackingParityTest

The historical events were being transformed twice and that influenced how the reference point was used in the tracker. Removed the historical transformation. Added a new test to check the parity between lists: flinging a similar list in both Views and Compose should get us to a similar item position.

Fixes: 293188485
Bug: 269487059
Test: Previous Tests Should pass and added new tests.

Ok so back from holidays and tested with a recent snapshot 10683443 that contains this and it's still broken for #62 #53

BTW I also got a new strange crash with that snapshot : https://issuetracker.google.com/issues/295745063#comment14 that is touch related, maybe you have an idea.

Hey, I'm looking into 53 now, I'll let you know if something's up. From what I understand in your logs in 62, "Not Working" happens when you activate the flag and "Working" when you disable it, right?

Yes exactly.

to...@gmail.com <to...@gmail.com> #67Aug 31, 2023 02:35PM

Are you able to reproduce with the given code or need more?

le...@google.com <le...@google.com> #68Aug 31, 2023 03:57PM

Hey, yeah, I'm working on a fix for everything :D I'll update here once it lands.

le...@google.com <le...@google.com> #69Sep 4, 2023 11:59AM

Hey, I submitted a fix for this last Friday so if you want to have a look before the next release I think you can just use a recent snapshot. The fix is still behind the same flag though. Let me know how it goes :)

to...@gmail.com <to...@gmail.com> #70Sep 4, 2023 02:04PM

Works with 10758292, and could not find regressions in the other parts of the app :)

That was a long running issue thanks for all the fixes.

Completely unrelated but do you think you can help me have https://issuetracker.google.com/issues/297231233 moved to higher priority and maybe someone available? This is highly impacting issue with a simple repro I was able to make for once.

to...@gmail.com <to...@gmail.com> #71Oct 22, 2023 01:58PM

So I do not have a Samsung device but it seems on some device Samsung allows apps to run in popup windows.

When in that mode the app does not receive any input at all. Even when leaving that mode does not restore touches. Only kill app and restart.

No idea what to log if you can't reproduce. But will again need you here.

Edit: Seems this also happens with Lineage OS that offers the same feature. (But can't reproduce on pixels with freeform dev option enabled)

Flipping the VT bug fix flag

Now VelocityTracker will have the bug fix by default.

Relnote: VelocityTracker will now have the fix for adding points on by default. The fix can still be turned off by setting VelocityTrackerAddPointsFix to false if there's any issues.
