What is the recommended way of drawing text inside a 

Canvas

 composable since there is no 

drawText

 method. I have a requirement where I rotate the canvas and draw some lines with some text. I'm currently using 

drawContext.canvas.nativeCanvas.drawText

Hi! When using compose in a multi-module project do I have to specify

composeOptions

+

useIR = true

+

buildFeatures.compose = true

for each module or is it enough to specify all (or some) of these in the

:app

module? Setup instructions have only app module example (which unfortunately is true for many examples in docs: they assume a single app-module structure)

Hey, I'm trying out Ktor's WebSocket client library. It returns incoming messages from a web socket as a

SharedFlow

- I'm trying to figure out how to keep the web socket session (

DefaultClientWebSocketSession

) running in the background so that I can collect the

SharedFlow

messages and display them on screen as they stream in into a

LazyColumn

or similar. I'm not sure how to fit this into Compose's state tools. I tried using

coroutineScope.launch{}

with

rememberCoroutineScope()

but it seems like the web socket session would stop as soon as the coroutine scope ended.

hey! I’m playing with BottomNavigation and Jetpack Navigation and I did an sample based on @Afzal Najam post ( thanks man🙏 https://afzaln.com/multiple-navigation-graphs-with-jetpack-compose-navigation/) Here’s my code: https://gist.github.com/nglauber/5061cbbafd63488131380b09c8943ad7 I have two questions: 1. When the second tab is selected and displaying its root content, is there a way to display the first tab when the user presses the system back key? 2. Could someone point out where can I find a way to save the

LazyColumn

scroll position? In my sample, the first tab is a list.

drawLine(
    brush = SolidColor(Color.Red),
    cap = StrokeCap.Round,
    strokeWidth = 8.dp.toPx(),
    start = middle,
    end = Offset(midX, 16.dp.toPx())
)

Can anyone help me with this, when we draw a line using the above code,

end

mean we ending that line at some position, But with

Offset(X,Y)

Y having

16.dp.toPx()

what does this mean? I am increasing Y offset like

100.dp.toPx()

, line is becoming short in length Why?

Does anyone talk about the performance of Jetpack Compose? I have tried various samples e.g JetNews and the scrolling, behavior and transitions of different elements does not match native elements like RecyclerView. Is this expected because compose is not fully native?

What is the latest compose version? I was using alpha09, but Android Studio mentioned that SNAPSHOT was available. Can’t find any release notes, and isn’t SNAPSHOT before alpha?

Is there an option in AS Canary to automatically refresh Compose previews?

In the past convention was to put

Modifier

as a first parameter of a

composable

. Did it change? Am seeing more and more samples, including Google ones, with

Modifier

as the last parameter. Where it "should be" put?

Hi, can someone help me? How can I set the cursor position in a text field? The equivalent of

editText.setSelection(position)

with the classic android view system. thanks

My first screen that I did in compose! The entire fragment is only ~70 lines long, but I don't think it's idiomatic. Can anyway take some time to critique? https://gist.github.com/ColtonIdle/85db918c763076cbb147b722e6807007

Question about

mutableState

and

State

: in the "Using State in Jetpack Compose" codelab, it says:

State<T> is intended to be used by Compose.

Application state that's used outside of Compose should not use State<T> to hold the state.

Why is this? Is

State

being discarded along with the compose-recompose lifecycle or something? Does anyone know the lifecycle of

State

?

Having issues with Compose

TextField

sometimes opening keyboard properly when I click on the textfield, and sometimes not. Is anyone else seeing these issues? Working thru "Using State in Jetpack Compose" codelab

Hello everyone,im trying detect swipe direction in compose.Im using draggable modifier for this.But draggable allows only one direction to detect(Vertical or Horizontal).I want to detect swipe for all direction(left,right,up,down).May anyone help me how can i do this?Thanks.

If one of the items in a Row is using

fillMaxHeight

and one of the item's height is conditionally dependent upon some state, don't we have any other option than writing a custom layout to get wrapContent behaviour? Currently

fillMaxHeight

makes the row fill the entire height but what I meant was the maximum height of an item in given row

How can we add a custom scroller to

LazyColumn

?

Is there any rule for posting? Big chunks of codes and error logs are irritating. We could use gist or something else

Is it possible to use compose for Custom Snackbar Layout which to be used with lagacy xml based Fragment?

When to use

ScrollableColumn

vs

LazyColumn

? Is it equivalent to RecyclerView vs ListView?

hey guys, can you help me with this simple question: How can I check for “preview” state inside composable? Can I know when the view is rendering in preview environment?

What would be the best way of linking a broadcast receiver to a Composable? At first I thought the best idea would be to use a live data / android viewmodel scenario, but this does not seem to work (unless I am doing it wrong): my values are always null on arrival. I also tried to simply pass the broadcast receiver data into a function and send that to my Composable. My values are updated when I use the function (using a Toast message) outside the Composable, but not when I pass the values to the Composable. Any ideas?

What is considered the best way to connect a ViewModel to a Composable? Using a "mutable"

StateFlow

or

LiveData

that is "collected as state" and receive new values directly (e.g.,

onChanged = { vm.stateFlow.value = it }

or creating a "local remembered state" and passing it back only when necessary (e.g.,

onClick = { vm.onClick(myRememberedState.value) }

). 🤔

I'm tryna use Jetpack Compose with latest 1.0.0-alpha09 version and I can't find @Preview. Did they delete it?

The usage of

android:configChanges

with some flags (

orientation

for example) will be the standard in the future? I think that Compose can manage better the responsibility. In case of an affirmative reply, extending the ViewModel should be useless?

When I try to preview a composable I get Render problems, but I can't figure out what the problem is about:

@Preview
@Composable
fun TestPreview() {
    Text("Hello World!")
}

I'm on alpha09 with latest IDE.

Hello, I'm getting started with compose and was looking at

LazyColumn

and

LazyColumnFor

when should one or the other be used? I see that

LazyColumnFor

calls

LazyColumn

internally

Has anyone gotten compose to work in an application with proguard? Looks like my app wont launch anymore due to enabling compose. I'm not 100% sure it's composes fault yet, but it's the most glaring change so far.

Is there a known issue with using TextOverflow.Ellipsis and TextAlign.Center together with the text sometimes getting cut off? I tried searching for a related issue but didn't find one, so wanted to check if anyone else has ran into the same thing.

https://twitter.com/tikurahul/status/1346562479204126720 I see compose compiler is taking contributions on github and after digging into the repo, it seems that compose is also hosted there? Or am I interpreting it wrong and it's on the compose compiler?
