kandi X-RAY | accompanist Summary
Accompanist is a group of libraries that aim to supplement Jetpack Compose with features that are commonly required by developers but not yet available. Accompanist is a labs like environment for new Compose APIs. We use it to help fill known gaps in the Compose toolkit, experiment with new APIs and to gather insight into the development experience of developing a Compose library. The goal of these libraries is to upstream them into the official toolkit, at which point they will be deprecated and removed from Accompanist.

Update: original question followed by updated sample code that triggers it as requested.
I have a list of times broken down by half hour in a lazy list
E.g 12:00, 12:30
The list is attached to a horizontal pager from the accompanist-pager library
When a user is swiping between pages, I need to update the selected time, and I want the selected time to always be in the center of the screen, if it's not near the top/bottom where that can't be the case.
The only way I've figured out how to accurately do this with the methods provided to us is as below.
Note: i have previously captured the button / list height....

Your pager behaves strangely because you're creating its state on reach recomposition:
Scaffold for my main screen with a fixed
bottomBar that is visible in every screen of the app, and I'm applying the
innerPadding of the
Scaffold to its content.
I want the keyboard to appear over the
bottomBar, and for that I'm applying the
imePadding() only to the
However, when the keyboard is opened, both the
imePadding() are applied to the contents padding.

Is there anyway that I can prevent it and apply only one or the other?

If you need to hide status bar completely, you need to use a full screen theme, like showed in this answer
Since Compose 1.2.0-alpha03, Accompanist Insets was mostly moved into Compose Foundation, check out migration guide for more details. The main changes to below answer is that
ProvideWindowInsets is no longer needed and some imports should be replaced.

It's a bug and I've reported it.
Until it's fixed, the easiest solution at the moment is to switch to
scaleOut transitions, they work fine.
An other option is putting
AnimatedVisibility is a
Box of FAB static size, which is
56.dp, in this case other transitions work fine, except the clipped shadow. The shadow can be disabled by zeroing the
elevation parameter, which is not the best solution either.

I got this error because of an incorrect import:
I need to create a reader screen for a book reader app in android and I need to have a a composable like swipe refresh that comes from the bottoms of page so the users go to next page.
I tried a google Accompanist vertical pager and swipe refresh and in all of them swipe refresh comes from top of screen. is there any alternative for swipe refresh that comes from bottom of screen? or even a something that replicate dragging from bottom of screen.
thanks in advance....

The issue is that your compile SDK is 31, you are targetting API 31 (Android 12) and not setting the exported attribute.
You need to specify
android:exported="true" in the manifest.
If your app targets Android 12 and contains activities, services, or broadcast receivers that use intent filters, you must explicitly declare the android: exported attribute for these app components.
I am using a
BottomNavigation with 4 composables. All of them have a
LazyColumn with each item in the
LazyColumn having an image populated from the network using Coil for Jetpack Compose. Similar to Twitter/YouTube.
When I navigate between these items, the composables get destroyed and recompose only when navigated back to them. Even the coil images are cleared and re-fetched (from memory or local storage) when navigated between these composables. This is of course the expected behavior.
The problem is that this is causing the navigation between them to be too slow. Coil images take about 400ms to 700ms to load the image for every navigation. Apps like YouTube/LinkedIn are literally instant in their
When I was using XML for this, I would make the fragments(used as bottom nav items ) with an appear/disappear logic to avoid this time delay while navigating between them.
How do I achieve the same with Compose ?
I am using the following versions:...
ANSWERAnswered 2022-Feb-19 at 14:00
Well I had the same problem using
emulator or phone both work well with small simplistic composables. And when I create more complex Composable and try animating the navigation, using the accompanist animation library it gets very laggy.
But then I tried building the release APK file, since it is usually optimized and way faster, and that will significantly speed up your app. Here is link on how you can generate signed APK then install it on your phone or emulator and see if that fixes your problem!
You could also check if you accidentally disabled the hardware acceleration from the manifest. Make sure you set
android:hardwareAccelerated="true" in you activity tag.
In case that does not help either, then you have to implement your own animation and use Shared ViewModel, for communication and triggering the transition from one Composable to another. The idea is that you can use modifier
offset property to show/hide the Composable by placing it outside the screen.
First set your ViewModel, and add mutable state variable, that will trigger the transition from Home to Settings and vice versa.
This is not the best practice, since there is no way to directly pass data from one composable to another as you would normally do with the normal navigation. But you can still share data using the Shared ViewModel. Using this method it will not recompose your Composable, and thus be really fast. So far I have no problem with any out of memory exceptions even on some very old/slow devices with 2GB RAM.
