Hi ! I will try to repost my question 😕

What could happen if I would use different libraries with different kotlin version ?

Do you update your project's kotlin language's version only when all the imported libraries are updated ?

Just ran into a runtime crash after updating to 1.5.0 with an Android Emulator running on API 16:

E/AndroidRuntime( 3715): Caused by: java.lang.NoClassDefFoundError: kotlin.collections.EmptyList
E/AndroidRuntime( 3715):        at kotlin.collections.CollectionsKt__CollectionsKt.emptyList(SourceFile:71)
E/AndroidRuntime( 3715):        at kotlin.collections.CollectionsKt.emptyList(SourceFile)
E/AndroidRuntime( 3715):        ... 16 more

However, this crash does not happen on newer versions of Android (API 29) or if we have

kotlinOptions.useOldBackend = true

, any idea what's the underlying cause in the new IR back-end that would cause it to crash on older versions of Android?

Hey everyone, I recently study about advantages of using single activity in an app. so while building my own app I started to wonder if it is recommended to have login/signup fragment and home screen in a single activity. if anyone has any opinions on this, please share. Thank you in advance. 🙂

I am about to start developing but before that i want to take knowledge about it, can you guys guide me for the same please? Any platform for that?

I haven't really kept up to date with flow as a replacement for LiveData. I use LiveData currently to connect my AAC ViewModel to my Fragment. I looked up some quick articles and it seems like I would replace my LiveData usage of:

private val _name = MutableLiveData("")
   val name: LiveData<String> = _name

with StateFlow like this

private val _name = MutableStateFlow("")
    val name: StateFlow<String> = _name

Is that pretty much it? I do plan on reading/learning more about it, but I'm just trying to get a POC done and just wanted to make sure I'm not breaking any rules here that I don't know about. Cheers

How to create only one instance of ViewModel for my @Composable screen? Now every time when I call my @Composable, new ViewModel is created.

@Composable
fun BankScreen() {
    val viewModel: BankViewModel = viewModel()
}

Tried to follow https://insert-koin.io/docs/reference/koin-android/compose/ but Android Studio throws weird error

Are there hot reload in android native kotlin for android studio 4.2, if there aren't so when we get hot reload?

Does anyone know how to apply anti-aliasing to an image while downsizing it in Android? I’ve tried every answer I can find on SO or in blogs, and nothing seems to work.

For general android development, should I use jdk7 or jdk8?

Hello. Can we bind to StateFlow<T> with a binding adapter? How should I write the adapter? I wrote an adapter taking T and an adapter taking StateFlow<T>. It does not work

This message was deleted.

Is it possible to simplify this code?

private fun setActiveLabel(textView: TextView) {
    binding.apply {
        accounts.isSelected = binding.accounts == textView
        cards.isSelected = binding.cards == textView
        loans.isSelected = binding.loans == textView
        funds.isSelected = binding.funds == textView

        accounts.isActivated = binding.accounts == textView
        cards.isActivated = binding.cards == textView
        loans.isActivated = binding.loans == textView
        funds.isActivated = binding.funds == textView
    }

    when (textView) {
        binding.accounts -> { binding.accounts.setFocusForAccessibility() }
        binding.cards -> { binding.cards.setFocusForAccessibility() }
        binding.loans -> { binding.loans.setFocusForAccessibility() }
        binding.funds -> { binding.funds.setFocusForAccessibility() }
    }
}

I use the 'shell scripts' feature from the JetBrains Toolbox (JBT) a lot. I think that since the Android Studio (AS) 4.2 upgrade it started behaving differently: - ⬅️ Before, when running

studio .

(e.g. in a repo root) it would open AS in that directory. Running it again would open the existing AS project window. - ➡️ After, when running

studio .

it opens the project in a new AS window every time, even if there already is an open window for the project. This is an issue, because during the day I run

studio .

quite often and I end up with too many windows for the same project! Do you have this problem too? Do you know how to fix this? Is this and AS or JBT issue?

How I can pass my

NavHostController

as lambda down? I tried:

val appNavController = rememberNavController()

composable("loginScreen") {
    LoginScreen(::appNavController)
}

@Composable
fun LoginScreen(navigateToLoginDetails: (details: String) -> Unit) {
    ....
      navigateToLoginDetails(details)
    ...
}

Hi can anyone help me show network error to user when wifi is connected but no internet access like youtube?

Has anyone ever come across a UI issue submitted by a user where UI elements are just bizarrely missing from the layout? I can't reproduce an issue a user from a Samsung Galaxy S8 has sent me where entire ui elements are missing. I've tested display sizes, text sizes, and more but still no way to reproduce it.

hi everyone! I have a question: If I have a

lifecycleScope

and I want to run some job that either runs after a certain time or event (so can get cancelled) what is the best way of doing so? For example, using:

val job = supervisorJob()
val myScope = lifecycleScope + job

// Somewhere else
job.cancelChildren()

Is not working out, because the

myScope

stays alive after the `lifecycleScope`is cancelled Using

var job: Job? = null
val theWork = lifecycleScope.launch {
    // delay, do the work
}

// Somewhere else
job?.cancel()

This would work, but then I always have to keep track of the job. Is it possible to have a lifecycle respecting scope on which I can cancel its children when necessary?

Hi, is there a way of controlling the position of Keyboard on screen? We are modifying the Window manager with 

wm overscan

, to hide navigation controls all-together (you cannot swipe down to bring up notification shade). But this also moves the keyboard, and hides part of it. Our application is always in landscape and is the only one running. Hacky solutions are welcome.

Do you guys memcache database query Flows/Observables via `replayingShare`/`shareIn` and friends?

I have some problem with suspend in a Interceptor. I use a interceptor to refresh token:

@Singleton
class RefreshInterceptor @Inject
constructor(
 private val savePrefSecurity: SavePrefSecurity
) : Interceptor {
   
    override fun intercept(chain: Interceptor.Chain): Response {

       
        var request = chain?.request()
        var response = chain!!.proceed(request)
           if (response.code == 401) {
            var refresh = savePrefSecurity.getSValue(REFRESH_TOKEN)
            if (!refresh.isNullOrBlank()) {
                )
                GlobalScope.launch {
                    var refrehResponse = api.refreshToken(sendRefresh)
                    [....}
                    // other code...
                     return@let intercept(chain)
                }
            }
}
   return response

1. how can i avoid GlobalScope ? because refreshToken is a supend function 2. i think that return@let intercept(chain) is inappropriate blockin

Hi goodnight, do you know how I can share my login data saved in my application with another application? Grettings

Hey people, I’ve got a question about collecting the state from the VM in compose: which one of these is best practice to follow?

private val _uiState: MutableStateFlow<UiState> = MutableStateFlow(State.loading())
    val uiState: StateFlow<UiState> = _uiState

    init {
        viewModelScope.launch {
            repository.getData()
                .map { resource ->
                    Log.d("VM", "got $resource")
                    State.fromResource(resource)
                }
                .collect { state -> _uiState.value = state }
        }
    }

or

val uiState = repository.getData()
        .map { resource ->
            Log.d("VM", "got $resource")
            State.fromResource(resource)
        }
        .stateIn(
            scope = viewModelScope,
            started = WhileSubscribed(5000),
            initialValue = State.loading()
        )

And calling them from the activity

val state by viewModel.uiState.collectAsState()

I am also noticing some heavy delay when the api is executed:

I/Choreographer: Skipped 136 frames!  The application may be doing too much work on its main thread.

Hi guys, I am in a situation that our backend team is unable to provide us with a paginated endpoint for a large dataset. Any tips/articles on how to handle huge json responses with coroutines/flow? (I’m using retrofit for networking)

Hello, how could I convert the bellow Swift code to Kotlin? I'm coming from iOS and I use a Redux implementation for state management ("state")

state.list = state.list.map { listItem in
        if listItem.id == action.payload.id {
            var listItem = listItem
            listItem.title = action.payload.newTitle
            return listItem
          } else {
            return listItem
          }
        }
