Hi Team, is ktlint support Compose

Hi, guys What’s the difference?😆

typealias HttpCall<T> = suspend () -> Response<HttpResult<T>>

suspend fun <T> HttpCall<T>.doTransform(): Try<T> {
    return try {
        invoke().run {
            if (isSuccessful && body()?.statusCode == 200) {
                Right(body()!!.result)
            } else {
                Left(Exception(body()?.message))
            }
        }
    } catch (e: Exception) {
        Left(e)
    }
}
//getToken is a REST API by retrofit
val httpCall: HttpCall<AuthenticationToken> = { service.getToken(params) }
httpCall.doTransform() // OK
{ service.getToken(params) }.doTransform() // failure

hello all Any ideas why android studio debuger is not showing local variables in suspend functions?

A 'return' expression required in a function with a block body ('{...}'). If you got this error after the compiler update, then it's most likely due to a fix of a bug introduced in 1.3.0 (see KT-28061 for details) this error makes no sense because there are return expressions at all points.. wth This happens when using runCatching inside a suspend function. How can I solve this?

Kotlin is not happy today... Is this a bug?

Hi. I'm going to use ktor to build an android application that serves https server. The problem is that how can I generate(or get) bks keystore that has trustful certificate. When I use self-signed certificate, the browser notifies that certificate is not trustful. But If I'm going to trustful certificate from a bks keystore, then sslConnector crashes app because of null alias.

For anyone working with

WorkManager

’s `CoroutineWorker`s, is there a way to run clean up work during

onStopped()

? looks like this is marked as

final

in the implementation for some reason

i have difficult to understand this val intent = Intent(this, MoviesList::class.java) what "::" means?

enum class ScreenState(val error: ErrorAlertType? = null) {
    LOADING, ERROR, OK
}

enum class ErrorAlertType {
    CONNECTION, UNKNOWN
}

and then

val state = ScreenState.ERROR(ErrorAlertType.UNKNOWN)

How I can define my 

ScreenState

to get optional parameter for 

ERROR

state?

Is it a good idea to call a function in the ViewModel and pass a function as the callback instead of using LiveData or other flow? Is there any memory leak doing this?

I have an enum class that I'm trying to mock using mockito. All I'm doing is

val category = mock(Category::class.java)

where Category is the enum. And when I run the test I'm seeing a

NoClassDefFoundError

I already added the mock-maker-inline file but any thoughts on what I'm doing wrong here?

Hi, I am newbie :). I have just one query about jetpack composer. Does anyone know about remoteview example making with compose for home widget? Our team want to percent based layout but it is so complex with current remote view 😞

I have to support deep link in my app. I have a deep link activity ( transparent activity) where I have all the re routing logic. The app uses navigation architecture component. But building back stack seems to be a problem. Since we have activities and some fragments. If I deep link to a activity hosting one fragment when app is not opened on clicking back the app exits. There is no other activity in the stack. I do understand that if you have all fragments and you deep link to fragment navigating up will take you to the start destination in nav graph. Is there a way to keep the existing code base and still have a proper back stack.

am writing tests for my

ViewModel

that exposes state with

StateFlow

. I want to test that it emits

Loading

state and than starting data fetching process from

init

block. when I provide fake API I can’t catch

Loading

state because data is fetched immediately and

Success

state is emitted. how to test that

Loading

comes first followed by

Success

?

Please has anyone here worked on an android recovery system before?

Do we need to import kotlinx-coroutines-android dependencies to use coroutines with kotlin? Kotlin has it’s own coroutines implementations right? What’s the diference between the two?

Hello everyone! I'm trying to use a ListAdapter, with a list in which items are not unique. Items are kinda like this:

data class Item(val a: String, val b: String)

My problems comes trying to create a DiffCallback: If I use oldItem == newItem on

itemsAreTheSame

, this is going to return true on items that are not the same, for instance, the first two on the following list: Item("a", "a") Item("a", "a") Item("b", "b") As long as an operation doesn't involve items with the same content, everything works fine: animations, add, edit, move, delete. But this gets buggy when items are equal. If I delete the second item, the first one will also be deleted. If I add or move something, the animation is wrong, kind of reversed. What I wanted to know is if there's any other way to handle something like this, without adding an identifier, nor using a custom differ without ListAdapter.

I'm wanting to use an ExpansionPanel (https://material.io/archive/guidelines/components/expansion-panels.html) in Compose. However I can't seem to find the right function. Can anyone help me please?

viewModelScope

and

lifecycleScope

both run on the Main Dispatcher. All the official and unofficial examples of these scopes together with a

StateFlow

or

SharedFlow

show this:

.stateIn(viewModelScope, ...) or .sharedIn(viewModelScope, ...)

. But this means that all the calculations (for example when using

combine

) then run on the main thread. Wouldn’t the better default be to always run

SharedFlow

and

StateFlow

in

viewModelScope + Dispatchers.Default

? When collecting the flow, it will run in another coroutine anyway, and UI operations can be done on the Main dispatcher.

Hi, facing this issue, did anyone faced this and tackled it? https://stackoverflow.com/questions/69678819/exception-in-android-app-failed-resolution-of-lorg-jacoco-agent-rt-internal-8f

Is there a way to pass the right hand side of

{SomeObject} is {SomeClass}

as a parameter? I am trying to perform type checking inside a function where the type to check for meeds to be passed as an argument. Any way to achieve this?

hello, With the new navHost how do you pass data to an activity destination? With composable you can use the NamedNavArguments. But these seem not to be available for activities? Is there a way to pass parcelable data that you could put in the intent of the activity you are starting?

Hello! Are there any plans for Databinding to use KSP instead of Kapt?

Simpler way to add a common filter to reduce the same variable call

}

if i have a

value class

, can I send it through a bundle as the type of it’s backing field? or do i need the class to be

Parcelable

?

Hey, I want to share a project on Github from Android Studio (Artic Fox) to get some feedback, but no matter how hard I try the initial commit operation always fails with the error "GIT_ASKPASS_TOKEN environment variable is not defined!" For some context, I integrated Android Studio to GitHub via personal tokens, with the right permissions and set to expire next month. I tried making new tokens too, but that didn't help. Googling the issue didn't bring up any good solutions to this either. I'm stuck. What should I do?

Hi guys. Hopefully this is the best place to ask. I'm currently evaluating building our app in Kotlin Multiplatform. There is a separate iOS project being developed, but the idea is to keep the door open to implement the iOS version in the KMM project later down the line. I've been researching app architectures, and there doesn't seem to be a main consensus on the best one to use (even a link to a page on the kotlin homepage discussing this is no longer available). One of the requirements is we'll be using Jetpack Compose and SwiftUI, and it seems only the MVI pattern allows us to be truly multiplatform without separate presentation logic and testing. The issue is that most of these articles i've been reading are a few years old now, and I wanted to know what the latest recommendations are? I found the todoapp example project which seems to satisfy our requirements. Would this be the recommended way to go? https://github.com/JetBrains/compose-jb/tree/master/examples/todoapp
