Hi, is any one facing with gradle dependencies not resolving due to time out ? This is happening from today morning. Not sure if some of the standard repositories are down.

Hi I have one small doubt about flows:

StateFlow

to be specific I have

MutableStateFlow<UiState>

and corresponding

StateFlow<UiState>

defined in my viewmodel

class MainViewModel:ViewModel() {
    private val mutableUiState = MutableStateFlow(UiState())
    val uiState = mutableUiState.asStateFlow()
    // ...
}

And my UiState is roughly defined like this

data class UiState(
    val propertyA: Int = 0,
    val propertyB: Boolean = false
) {
    private var mutableProperty: Int = 0

    val derivedProperty: Boolean
        get() = mutableProperty % 2 == 0

    fun someMethod(newProperty: Int) {
        mutableProperty = newProperty
        // some extra logic goes here
    }
}

Now the doubt is that in my viewmodel I’m calling

mutableUiState.someMethod(someInteger)

but I think

uiState

is not getting updated because I have used

uiState.derivedProperty

at some place in UI in compose and the UI is not updating. Someone care to help what I’m doing wrong? Thanks

Hello, I use Kotlin in my Android App. I'm a bit confused about the Companion Object in an Activity Class. Can the companion object be used as an Activity State? For example, I have an activity with a MutableListOf<Item> and I have set it in companion object. Is it a good practice to update the list of this class from other classes?

Hi guys, I am having difficulty mapping a List of Posts Flow exposed form the Repository to UI data in the viewmodel

//Repository
data class PostResponse(
    val body: String,
    val title: String,
    val id: Int,
    val userId: Int
)
class NewsRepository @Inject constructor(private val newsRemoteDataSource: NewsRemoteDataSource ) {

    val fetchLatestNews : Flow<List<PostResponse>> = newsRemoteDataSource.fatchLatestNews

//ViewModel
data class UiPostResponse(
    val post: PostResponse,
    val message: String = "message"
)
class UiViewModel @Inject constructor(private val newsRepository: NewsRepository): ViewModel() {

private val data : Flow<UiPostResponse> = newsRepository.fetchLatestNews.map { post->
UiPostResponse(
  //
)
}

Please what would be the best way to map a list of flow data to useful UI data in the viewmodel?

When a class is marked as a data class, would the generated functions result in the APK size to increase? or would proguard remove it?

How can we update a singleton component if we have any param changes to be applied to any given @provides method using Hilt dependency injection? Since Singleton components are initialised initially itself and if we have to update any keys to the

etc (if we are setting keys dynamically and not locally) how do we achieve the same with Hilt? Ref: Similar use case to this issue

I've got a Data Sync service that I'm moving to

WorkManager

, and it can potentially run for a long time, so I launch it with

setExpedited

and setup the

ForegroundInfo

to display a progress notification and keep it foreground. But now it fails in Android 12+ because of the new restrictions. Is there now no way to launch a long running task like this from the background? i.e. schedule a job once a week to do a data sync and have it run foreground?
