How to use AS stable with Compose: https://marcellogalhardo.dev/posts/2021/03/30/using-compose-beta-on-as-4-1/ I haven't tried it yet, but it would be nice to get a blessing/official documentation on how to do this. A lot of people I've spoken too have said that they want to adopt compose, but don't want to force canary or AGP 7 if they don't have to.

Can I query a composable for its height and width dimensions? The use case is downloading an image in a specific size (to save bandwidth). In standard Android I would do something like

view.onLayoutDone { view ->
  downloadImageWith(view.width, view.height)
}

Extremely simplified of course, but you get the idea.

Is it possible to use only one activity and

@Composable

functions? Do I have do use fragments?

Is there a way to tell a

Row

to invert the order it lays out its content? (e.g. LTR instead of RTL)

I wrote a start screen, and then used the delay method to launch the main screen, but I found a problem, as long as I write navController.navigate after the delay method, I need to press the return button twice to end the program, but without the delay method only need to press once to end the program, I guess it may be a problem of the delay method, how should I fix it?

val delayedHandler = Handler()
delayedHandler.postDelayed({
    navController.navigate("mainPage") {
        popUpTo("welcome") { //delete
            inclusive = true //close stack
        }
    }
}, 2000)

Is there a default padding end/start for AlertDialog ? I was checking my implementation on a small device (3.7" - 480*854 - hdpi) but these padding are missing. As you can see on attached screenshot the alertDialog on the small device, the dialog is taking fullscreen width. Strangely it's working fine on bigger devices. Why so ? I checked on Compose sample and they never customize the modifier parameter of Alertdialog. What is the intended behaviour ? Should we always implement our own start/end padding to avoid this issue or is it a bug from AlertDialog implementation in Compose ?

Hi all, I'm trying to implement video trimming similar to this image but wondering about the good way to do the UI part in Compose: I made a prototype with 2

Slider

components but they're not very customizable and I can't put one over the other over the "timeline" because only the top-most one is interacting then. I'm thinking I need to implement a custom

DoubleSlider

but it seems complicated, any thoughts ? Thanks 🙂

Hi Everyone, can anybody know how to refresh the compose function?

Is it possible to compile compose code as KotlinScript? Maybe someone can give me a hint. I think i have to enable the compiler plugin of compose. But i do not know how to do that.

This crashes with

IllegalStateException: Start/end imbalance

@Composable fun A() = Row { if (true) return }

It does not happen if I remove the

if

or if I use

return@Row

How to increase the height of the composable after adding aspectRatio to the composable. I have this usecase where you will have square box after some condition, I need to increase the height of that composable.

Hey, anyone tried already accompanist-pager?

Side question, how to tell AS to not reformat the whole file every time I hit some

@Composable

autocomplete suggestion, adding tons of opinionated newlines and indentation? It's so annoying.

The documentation has this example if I want to add a state to my component:

var expanded by remember { mutableStateOf(false) }

Currently this gives me a compilation issue in beta2. I can write

var expanded = remember { mutableStateOf(false) }

But that makes more painful to use. Is this something that has changed, or a bug?

Hey Everyone, anybody know how to toggle between dark and light theme in jetpack compose.
