when for example I want to redirect from my app to SMS app with

Intent

, how do I do it in Compose?

1741924: Docs June 30th Update | https://android-review.googlesource.com/c/platform/frameworks/support/+/1741924 Jetpack Compose RC1 next week 🎉

How to set the Text's width in the same way we use to do with

android:ems

?

When I show a

Dialog

, the phone's navigation bar buttons are still usable even though they are dimmed & they do not cause the

Dialog

to be dismissed automatically even though

dismissOnClickOutside

is set to

true

. Is this a bug or I am supposed to enable a specific behavior for it myself?

I'm trying to understand why this code doesn't work as expected without

.copy()

in `remember { colors.copy() }`:

@Composable
fun ProvideAppColors(
    colors: AppColors,
    content: @Composable () -> Unit
) {
    val appColors = remember { colors.copy() }.apply { update(colors) }

    CompositionLocalProvider(
    LocalAppColors provides appColors,
    content = content)
}

Without

.copy()

, it only works for the first change in state. Full code: https://gist.github.com/alashow/e67a75d662a13ce5529317bde3e241c2

Kinda tiny bug report:

unregisterComposition

is called twice in this screenshot (hope it is clear enough where it can be found. This is 1.0.0-beta09 by the way).

So with RC at the corner and Kotlin compiler still not stable enough to allow multiple versions support. Is there any documentation about how the Kotlin compiler version will be handled after 1.0 final since they are very tied?

Is there maximum Width Constraint in Compose? 🤔 I'm getting

Can't represent a size of 1168750 in Constraints

Error log when running this code

@Composable
fun Calendar() {
    Surface {
        Box(
            modifier = Modifier
                .padding(10.dp)
                .size(200.dp)
                .horizontalScroll(rememberScrollState())
        ) {
            CalendarBox()
        }
    }
}

@Composable
fun CalendarBox() {
    Box(modifier = Modifier.width(500_000.dp)) {
        Text(text = "Event 1", modifier = Modifier.offset(x = 50.dp))
        Text(text = "Event 2", modifier = Modifier.offset(x = 499_950.dp))
    }
}

@Preview
@Composable
fun CalendarPreview() {
    Calendar()
}

Basically, I want to write the widget that is very very wide. (Like calendar). I had similar code running in

View-based-approach

and it worked well. Now I want to translate that into compose based solution And I'm stuck with this issue. If this is framework limitation, is there any suggested approach how can I overcome this? 🤔

Is there a way to host a fragment inside of a composable? I know we can host composables inside of a fragment but what about the opposite?

Accompanist question - is there a way to apply ime padding without navigation bar padding? It's common for us to pass a

navigationBarsPadding()

modifier to different composables, but then one of them needs to also have the ime padding. And as docs say, calling

navigationBarsPadding().imePadding()

is not equal to

navigationBarsWithImePadding()

. Basically asking for an

imePadding

which is additive WRT

navigationBarsPadding

. Any hints on how to compute it?

Also question about accompanist and insets: There is an issue that

ProvideWindowInsets

has a certain delay, when used in fragment-based screens, which causes noticeable jumps with status bars. Are there any updates on that? (also bot closed the issue) https://github.com/google/accompanist/issues/155

What is the proper way to get the activity in a pure compose world for the external things that requires it like Play Billing?

Hey people, I’ve experienced a recent behavior while using interoperability where in my MainActivity this other dev set up a bottom navigation and I’ve been nesting compose navigations from it. The behavior is the be bottom navigation bar is bumped up with the keyboard. Is this an interoperability glitch? If you suggest it could be a glitch I would be happy to write a repo with the issue.

Hey all, I've been really struggling to get Compose to work with an existing Android project. I keep getting an error during compilation, and my googling of it hasn't been very helpful. I'm hoping someone here might have an idea of what's going on. Error message and more details in the thread...

Is it possible to do a visual transform without triggering a recomposition? E.g. say I want to use

Box(Modifier.offset(x=x, y=y)) { Content() }

but update x and y very frequently, while the contents of the box never changes. Right now I see the content get recomposed often, any way to avoid that? Is that in "future optimization" territory?

It seems that the BottomSheetScaffold doesn’t allow the “Half-Expanded” state of the Bottom sheet, what is the reason?

Facing this issue while adding

clickable

method in compose view

org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error: Exception during IR lowering

kotlin version : '1.4.32' compose version : '1.0.0-beta09' Let me know if anyone has any clue how to resolve this. cc @Ian Lake

I'm getting an NPE and I think I'm not understanding how snapshot state works? In essence I want to show a modal dialog as part of my state. Code inside the thread.

is there away to make the activity or the composable full screen?

Regarding

Snapshot.takeMutableSnapshot()

, when inside a

readObserver

callback, how do you subscribe a composable to reads of the supplied state instance?

Assuming that 1.0 release will come with stable AGP 7+ and AS Arctic Fox; is this correct? Would 1.0 still work with AGP 4.2+, though?

Is there a way to click Rects that draw use

drawRect

in Canvas?

Canvas(modifier = Modifier.fillMaxSize()) {
    list?.forEach { item ->
        val bounds = item.bounds // Rect
        // I want to click this
        drawRect(
            color = Color.Blue,
            topLeft = Offset(x = bounds.left, y = <http://bounds.top|bounds.top>),
            size = Size(bounds.width(), bounds.height()),
        )
    }
}

Is there a way I can

remember

the value produced by a

@Composable

function that does not have a

Unit

return type?

Is the

stack

(for overlapping ui) removed from compose 1.0.0-beta09? If so, what should I use instead?

Is anyone facing issues when generating a release build with Jetpack DataStore. I'm getting this on app start, I tried different proguard rules but didn't work Datastore beta02 Compose beta09 Using

Hello I'm starting with Compose and want to replicate Google Home's full screen clock screensaver called Eclipse - Dark https://i2.wp.com/9to5google.com/wp-content/uploads/sites/4/2019/01/lenovo_smart_clock_11.jpg?w=2000&quality=82&strip=all&ssl=1 However I'm completely stuck which composable to use. I started with a

Row

with some weighted `Text`'s inside, however how can I make the

Row

clip the

Text

? Do I need a fixed width - height for the

Row

and calculate the

TextStyle

fontSize manually or is there a better alternative?

@Composable
fun Eclipse() {
    Row(
        modifier = Modifier
            .height(IntrinsicSize.Min)
            .width(IntrinsicSize.Min)
            .background(Color.Black)
    ) {
        EclipseIntTile(0, modifier = Modifier.weight(1F))
        EclipseIntTile(4, modifier = Modifier.weight(1F))
        EclipseIntTile(5, modifier = Modifier.weight(1F))
        EclipseIntTile(2, modifier = Modifier.weight(1F))
    }
}

@Composable
fun EclipseIntTile(i: Int, modifier: Modifier = Modifier) {
    Text("$i", modifier = modifier, style = TextStyle(fontSize = 140.sp, color = Color.White))
}

Any pointers? Thanks

When Using Nested NavHost with a seperate navController in BottomSheetScaffold' Sheet , it AUTOMATICALLY EXPANDS! on launch , even when started using Collapsed State... Any Idea how to fix this?, Any help will be appreciated... Note: if i comment out navHost and simply use a Composable in Sheet it doesnt Expand automatically and everything works as Expected

Any one using ComposeView interop and noticing a slight lag when compose is starting up for the first time?

It will not. RC1 forked a week ago. Moreover, .20 has not landed in AOSP HEAD yet
