Hi everyone, I have an exo player view in portrait mode and on click of expand button I want to transition my screen to landscape mode and show the exo player in the full screen. I am getting the following error when transitioning from portrait to landscape. Code and stacktrace in thread.

java.lang.IllegalStateException: pending composition has not been applied

Hi. Is it possible to compile compose code in my app and generate UI? (Using compose compiler in app level)

I saw that changes were tracked and requested invalidation through

Recompoer#runRecomposeAndApplyChanges

. This function tracks changes and requests invalidation in the while statement and remains suspended until new changes are made through

waitWorkAvailable()

in the while statement.

awaitWorkAvailable()

works with

suspendCancellableCoroutine

and assigns

Continuation

to

workContinuation

if there is no scheduled task. The

workContinuation

is resumed in the invokeOnCompletion of a Job called

effectJob

. Therefore, in order for

workContinuation

to resume,

effectJob

must be completed.

Recomposer#close

, which completes it, is used only in the

withRunningRecomposer

function, but

withRunningRecomposer

is not used. So where does

workContinuation

resume? I had the same concern a month ago, but I still haven’t solved it. (Job.cancel is also possible to call invokeOnComplete, but cancel is used only for lifecycle handling through Owner)

Is there any way to allow

ClickableText

to pass touches to underlying components? In the case that the user does not click on a specific text, I hope that

ClickableText

can pass the click event without consuming the click event, such as a clickable

Card

I learned Java and most of kotlin and I want to start my journey with compose, I also built basic apps using swing I want to build an app that works on browsers, desktop and mobile devices

What is a proper way to use CustomTabsIntent with side-effects? it may to be called during recomposition.

I'm trying to make UI for a media3 player but I'm not sure how to make the player variables like duration into states that cause recomposition

is there a straightforward way to track the decay of velocity when scrolling LazyColumn? what I’d like is a way to track the decay as follows when I fling on my LazyColumn and it starts scrolling. let’s say the total scroll time for this example will take 2500ms: • at 0ms elapsed, the velocity would be 100 • at 500ms elapsed, the velocity would be 75 • at 1000ms elapsed, the velocity would be 25 • at 2000ms elapsed, the velocity would be 10 • at 2500ms elapsed, the velocity would be 0 (all example data of course, I’m just trying to illustrate the value I’d like to be able to track)

Looking for suggestions!. I have a bottom bar and navigation drawer in my top level destinations. I have other screens which also needs toolbar. Should i have scaffold in those screens as well or just a column and a topbar and hide the scaffold if its not a top level destination. I remember i saw thread related to this somewhere but cannot re-collect now.

Will the baseline profile be more effective if I don’t turn off animations when collecting the profile?

Hello, how can I animate the content whenever the keyboard opens/hides? Compose version:

1.2.0-rc02

Using accompanist-navigation-material's

ModalBottomSheetLayout

and

NavGraphBuilder.bottomSheet

builder, is there a way I can monitor the visible height of the bottom sheet in question? I want to pin a button to the bottom of the sheet, but it seems the actual height of the

sheetContent

is larger than what's visible and is hidden «below the screen», so to speak.

I can add system bars padding via

systemBarsPadding()

, is there a way to get the height of the system bars in

dp

instead of applying the padding directly?

I'm getting

Exception during IR lowering

after updating from

1.2.0-beta03

to

1.2.0-rc0x

(Couldn't inline method call), is anyone facing the same problem?

I was looking through some Compose widgets, and couldn't find where they are literally drawing their contents, is there a good example some where? Does it boil down to a canvas object at some point?

Does the 1.2.0-rc02 release support Kotlin v1.7.0? I guess not

Good morning everybody, is there any news about Glance Widget? The last update is from Feb 23rd https://developer.android.com/jetpack/androidx/releases/glance

I came across an article a little while back which had some recommendations about which imports to exclude to help improve efficiency when developing in Compose. But.. I can’t find it. Anyone know what I’m talking about?

Internals: Why does compose not use java.lang.ThreadLocal on JVM, but a custom ThreadLocal implementation?

Question: Custom Modifier What’s the difference between these two approaches?

vs

Hello all, wondering if someone can help with some issues I am having with google map animation using the Google Compose Maps SDK. Code in comments.

Hello, how do I treat every new parameter as not equal with the previous one even if the instance is the same? I have a pulse component and for testing I just send consecutive

Up

objects but it just reflects the first one not others(see the first row). I set

neverEqualPolicy

but it doesn’t work, tho. What is your take for such cases? Thanks!

val state = remember { mutableStateOf(initial, neverEqualPolicy()) }

sealed class PerformancePulseUpdate : Serializable {
    object Up : PerformancePulseUpdate()
    object Down : PerformancePulseUpdate()
    object None : PerformancePulseUpdate()
}

@jw As per https://jakewharton.com/multiplatform-compose-and-gradle-module-metadata-abuse, have you written all your UI from scratch without any Compose UI compoent?

How would I go about creating a player screen that has a mini player variant? similar to youtube

I’m failing to implement a ContentViewed event inside my composable as I have the following requirements: • Should get triggered when the composable gets displayed • Should get triggered when you are navigating back to that composable (like opening a new compose screen and do a back press) • Should NOT get triggered on configuration changes (e.g. orientation)

@Composable
fun MyScreen(viewModel: MyViewModel = get()){
   val items by viewModel.itemsToDisplay.collectAsState(initial = emptyList())

   ItemList(items)

   // when the UI is displayed, the VM should track ContentViewed (only once)
   LaunchedEffectContentViewed { viewModel.trackContentViewed() }
}


@Composable
private fun LaunchedEffectContentViewed(track: () -> Unit) {
    val config = LocalConfiguration.current
    var initialOrientation by rememberSaveable { mutableStateOf(config.orientation) }
    val orientationChanged = initialOrientation != config.orientation 

    var wasExecuted by rememberSaveable { mutableStateOf(false) }
    LaunchedEffect(Unit) {
       if (!wasExecuted) {
         if (!orientationChanged) track() // only track when orientation change was not the reason for recomposition
         wasExecuted = true
       }

       if (orientationChanged) {
            initialOrientation = config.orientation // update initialOrientation with new one 
        }
    }
}

I’m quite sure I’m doing something wrong with my

remember*

calls and I hope some can explain me what I have to adapt to achieve my requirements? I also created a stackoverflow question for that.

Is there some general consensus on appending “size modifiers” - eg.

fillMaxWidth()

to the modifier passed to a composable?

@Composable
fun MyComponent(modifier: Modifier = Modifier) {
    Box(modifier = modifier.fillMaxWidth()) {
        // ...
    }
}

On one hand, it feels like it hurts reusability, on the other it can remove some duplication. WDYT? Valid usage, frowned upon, should be avoided?

I am using compose maps library to display clusters of markers. Now to display a custom info window adapter I want to use the compose. I have followed the documentation of interoperability of compose via ComposeView. but when I add the ComposeView inside the info window method I am getting this error of cannot locate window recomposer.

Cannot locate windowRecomposer; View androidx.compose.ui.platform.ComposeView{e560fcf V.E...... ......I. 0,0-0,0} is not attached to a window

clusterManager?.markerCollection?.setInfoWindowAdapter(object : InfoWindowAdapter {
    override fun getInfoContents(p0: Marker): View? {
        return null
    }

    override fun getInfoWindow(p0: Marker): View {
        val composeView = ComposeView(context).apply {
            setContent {
                Text("Hello World")
            }
        }
        return composeView
    }
})

So is there any way to use the compose function inside getInfoWindow()?
