Hi, after updating to dev12, WithConstraints that's inside of AdapterList keeps getting called which freezes the list during scroll, and then the app crashes Structure:

AdapterList with Modifier.fillMaxSize()
-Box with Modifier.wrapContentHeight() + Modifier.fillMaxWidth()
--ConstraintLayout with Modifier.wrapContentHeight() + Modifier.fillMaxWidth() (I can also see non-stop constraints measure happening, it also gets logged)
---Box with Modifier.fillMaxWidth() + Modifier.aspectRatio(16 / 9f)
----WithConstraints
-----Image (but it also happens with empty WithConstraints block)

Crash:

androidx.ui:ui-material-icons-extended

removed in dev12?

Navigation component integration is "coming soon"?

What's the reason behind moving towards Modifiers instead of having composables like Clickable and Toggleable? I find it weird having to declare the modifier param everywhere. Is it just because of nesting?

drawRect

doesn’t respect parents

Padding

starting from

dev11

version

Values declared in

group

tags inside a vector drawable are not getting applied when I load the drawable using vectorResource. Should I extract them for each drawable and apply manually using DrawLayerModifier or is it something that's getting fixed soon? 🤔

A bug with

DropdownMenuItem

on dev12. A ripple modifier is applied after the clickable one, so the onClick listener passed to the composable is never invoked

We haven’t communicated anything yet 🙂

Trying dev12, getting this when I build:

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:compileDebugKotlin'.
> Could not resolve all dependencies for configuration ':app:kotlinCompilerPluginClasspath'.
   > Could not create task ':app:extractDeepLinksDebug'.
      > Cannot obtain value from provider of environment variable 'ANDROID_AAPT_IGNORE' at configuration time.
        Use a provider returned by 'forUseAtConfigurationTime()' instead.

any pointers?

How can I achieve FrameLayout behavior from dev12? Seems

Box

behaves like

Column

now and

Container

is deprecated

I read JetNews sample I saw this statement

val (postsState, refreshPosts) = refreshableUiStateFrom(postsRepository::getPosts)

I am a kotlin beginner, mabye could someone explain what mean ?

I can't find any specifics in previous conversations - is there some kind of scroll listener for AdapterList? If not, it may be worth passing ListState in itemCallback lambda as well, so we can have access to it? 🙆🏻‍♂️

With dev12, I’m getting this error in certain cases when subcompositions are involved. Has anyone else seen this with maybe

AdapterList

or

WithConstraints

?

Hi! launchInComposition this is called only one time due to the remember, but what happens if I want to call it more than one time? For example:

var text by state { "empty" }
var result by state { "" }
launchInComposition { result = getData(text) }
FilledTextField(
    value = text,
    onValueChange = { text = it },
    label = { Text("Label") }
)

I want to have build a carousel of image. I create ModelList, and load item from RestAPI and add into it. at AdapterList, I wanted to add Image, but I could not find a way to have Image which load from network url. anyone could help ?

I’m still trying to come up with a reproducer, with dev12 i’m starting to get this compiler error:

e: kotlin.UninitializedPropertyAccessException: Parent not initialized: org.jetbrains.kotlin.ir.declarations.impl.IrValueParameterImpl@e27c4d

Posting eagerly just in case @Leland Richardson [G] already fixed this one too 😜

AdapterList to display item in Vertically ?

I'm struggling with the following error when attempting to update my state from a WebSocket callback:

java.lang.IllegalStateException: Not in a frame

at androidx.compose.frames.FramesKt.currentFrame(Frames.kt:180)

W/System.err: at androidx.compose.frames.FramesKt.writable(Frames.kt:466)

I'm completely new to Android dev - most of my mobile dev before has been using xplat frameworks like Xamarin and React Native. I've managed to update to dev12. I suspect the problem is related to not being on the UI thread, but being so new to Android dev in general, and there not being many examples out there because Compose is so new, my Google-fu is failing me. Coroutines keep coming up but I can't quite work out the api. Can someone point me in the right direction?

Is not possible to download the Kotlin 1.4 plugin with Android Studio 4.1 Canary 10? Thread in Slack Conversation

Hi most of the time break points in composable functions are not working. I'm using dev12. Does someone have an idea?

There is no

hint

for TextField? 😮

This error highlight does not stop

Hi, could someone help me out by telling me, how I could create a declarative (without modifying xml) image slide in Jetpack Compose? I would appreciate it🙆‍♂️

I've been reading https://android.googlesource.com/platform/frameworks/support/+/androidx-master-dev/ui/ui-layout/samples/src/main/java/androidx/ui/layout/samples/SizeModifierSample.kt And I found it a little weird,

@Composable
fun SimpleSizeModifier() {
    // The result is a 50.dp x 50.dp red box centered in a 100.dp x 100.dp space.
    // Note that although a previous modifier asked it to be 100.dp x 100.dp, this
    // will not be respected. They would be respected if preferredSize was used instead of size.
    Box(
        Modifier
            .size(100.dp, 100.dp)
            .size(50.dp, 50.dp),
        backgroundColor = Color.Red
    )
}

So it's another way of adding padding but instead of add a padding value we create some empty space and put a 50x50 box inside it. Am I right?

Hi 🙂 Does anyone know how we can change the width of ModalDrawerLayout?

The world needs more magic. Put @Model back in.

Is kotlin 1.4-M1 compatible with compose dev11?

Also it would be nice if we could keep around the settings needed for older versions of compose.

Which kotlinCompilerVersion works with compose dev11? I found this in the forms:

kotlinCompilerVersion "1.3.70-dev-withExperimentalGoogleExtensions-20200424" //dev-11

But I get errors like this:

(24, 36): Class 'kotlin.Lazy' is compiled by a pre-release version of Kotlin and cannot be loaded by this version of the compiler

You can do this by setting the theme of the activity in your manifest
