"This project uses Gradle KTS build files which are not fully supported. Some functions may be affected." getting this issue when I load the project whats wrong with it

Does anyone know how to include implementation fileTree(dir: 'libs', include: ['*.aar']) in Deps.kt file

hello everyone, I couldn't make this data class as Parclable, the OData and orderItem: List<OrderItem> always has problems and i couldn't solve them the Question is how I can add them inside that parclable ?? thanks

data class Order(
	@SerializedName("data")
	val data: OData? = null,

	@SerializedName("success")
	val success: Boolean? = null,

	@SerializedName("message")
	var message: String? = null,
@SerializedName("order_item")
	val orderItem: List<OrderItem>? = null
)

If I'm using

Flow

as the bridge between a VM and a fragment, how can I ensure that the callback I use for the flow is initialized before I need It? The way I'm approaching it now seems like an antipattern.

private var loadedPosts: List<Post> = emptyList()
    private lateinit var loadedPostsCallback: LoadedPostsCallback
    val posts: Flow<List<Post>> = callbackFlow {
        val callback = object : LoadedPostsCallback {
            override fun setLoadedPosts(posts: List<Post>) {
                loadedPosts = loadedPosts + posts
                offer(loadedPosts)
            }
        }
        loadedPostsCallback = callback

        awaitClose()
    }

Yes I guess you can do that. But if you are trying to find out what extension function exist its not very discoverable. You have to know about the methods and which package they are in then add the dependencies etc.. just to be able to see the method signiture. Just makes figuring out what extension functions you can use and how quite an effort.

Hello guys .... How to Set BottomNavigationView in AndroidX with No ActionBar

i’m having trouble unit testing a flow. i have a

ViewModel

that converts a flow from my DB into a livedata for the view layer. the VM extends coroutine scope.

viewState.postValue(ViewState(loading = true))
this.launch {
    repository.observeAll().collect { observedList ->
        viewState.postValue(ViewState(list = observedList))
    }
}

and then in my test I’d like to do something like this:

val expectedList = listOf(Thing())
coEvery { mockRepo.observeAll() } returns flow {
    emit(expectedList)
}

viewModel.submitAction(Action.Refresh)

coVerify {
    mockRepo.observeAll()
    mockViewStateObserver.onChanged(ViewState(loading = true, list = listOf()))
    mockViewStateObserver.onChanged(ViewState(loading = false, list = expectedList))
}

but the

coVerify

coroutine completes before the second update to the

LiveData

. anyone have suggestions besides injecting the test scope or delaying?

Hello everyone, I have some problem about Cast

java.lang.ClassCastException: java.lang.Object cannot be cast to String[]

I want to cast Object to Array of Strings.

class BlockToday(val type: TodayType,var data:Any)

enum class TodayType{
    BANNER,EVENTS,CATEGORIES,TOP_SALES
}

val images = arrayListOf<String>()
val block = BlockToday(TodayType.BANNER,images)


=> bindBanner(block.data)
fun bindBanner(data:Any){
        val images = data as ArrayList<String> => Crash 
}

Any ideas to resolve this problem. ??? Thanks

Hi can anyone help me how to solve this error " cannot find symbol" when using the data binding

Hello you guys, So I have a question,Why we can not use

2. val categories = arrayListOf<String>()

Thanks

Hey! I’m having some trouble using DataBinding library. I have a binding method for View visibility:

@BindingAdapter("goneUnless")
fun goneUnless(view: View, visible: Boolean) {
    view.visibility = if (visible) VISIBLE else GONE
}

In the layout, it looks like this:

app:goneUnless="@{!user.isAdult}"

The value supplied to this binding method is a LiveData which, obviously, its initial value is null. The problem is that user property being initially null, databinding evaluates user.isAdult to false -> negated -> turns to true, but I would like the View to be gone at first, and only change visibility after I assign a value to user LiveData. Any thoughts on handling this in a more generic manner?

is there a shortcut in kotlin to crash the app?

<https://github.com/greenrobot/EventBus>

=> 2 years without update => Do you think it dead? Or anything can do the same things EventBus but written on pure Kotlin ???

someone else exeperienced exceptions thrown by retrofit which are not caught by the try catch surounding the call ?

I have a cross platform library for ios/android written in C/C++ and it would be nice to be able to call it from kotlin without all the JNI fuss

I tried a lot of answers on StackOverflow, but the image is sending as text and not as file

Hi guys, I'm wondering what do you use to download files? Do you just use DownloadManager? Do you use any library, e.g. FileDownloader, Fetch? I'm asking this because I'd like to pause downloads and maybe support concurrency and DownloadManager is a bit lacking in that regard. At the same time I see libraries like FileDownloader which at first sight looks awfully complex and I personally would prefer to not have to constantly (potentially) translate issues from Chinese.

Hi Guys , I have trouble regarding duplicate dependency. i have 2 SDK in the app ,of which both depends on youtubePlayerAPI.jar.

All examples i find to set the Java version to 1.8 are done under

But with kotlin DSL I get an error (there’s no setter):

Hello guys, How to resolve this problem ? I want to this value have default

I should change to

apply plugin: 'com.android.library'

, right ?

In my api response there is field called

isSuccess

to see if

post

or any other request is success or not. so thats why it return result OK(200) even if i have sent invalid values, so in above extension function on

can i check

isSuccess

variable from original

json

? Note: this extension function is called on

Response

from retrofit
