I’m having an issue with Compose

@Preview

rendering. This shows up as “Render problem” in the preview pane:

java.lang.NullPointerException: Parameter specified as non-null is null

The parameter referenced in the message is just a

text: String

which gets passed to a text composable

Text(text = text)

I want to extract the array data from the json response and store the data in my custom data class.

data class NewsData (

    val author: String, val title: String,
    val url: String, val publishedAt: String
)

class NewsViewModel : ViewModel() {

    // The internal MutableLiveData String that stores the most recent response
    private val _response = MutableLiveData<String>()

    // The external immutable LiveData for the response String
    val response: LiveData<String>
        get() = _response

    /**
     * Call getNewsData() on init so we can display status immediately.
     */
    init {
        getNewsData()
    }

    /**
     * Sets the value of the status LiveData to the News API status.
     */
    private fun getNewsData() {

        _response.value = NewsApi.retrofitService.getProperties().enqueue(
            object : Callback<ResponseBody> {
                override fun onFailure(call: Call<ResponseBody>, t: Throwable) {
                    _response.value = "Failure: " + t.message
                    //Log.i("response", t.message)
                }

                override fun onResponse(call: Call<ResponseBody>, response: Response<ResponseBody>) {
                    val root = JSONObject(response.body().toString())
                    val jsonArr = root.getJSONArray("articles")
                    val ob = jsonArr.getJSONObject(0)
                    val name = ob.getString("author")
                    _response.value = name
                }
            }).toString()
    }
}

This is the format of the json response.

After upgrading our project to K2 (Gradle 8.8) we've noticed that some

.salive

files are being created under

.kotlin/sessions

for some developers. Even after removal, after a few builds they keep coming back. Curiously, all files created are empty. I couldn't find more info on these files, are they important or just act like a log of some sorts? Is there a way to stop Kotlin from creating them?

If I convert a

Color

value to

Int

(using

toArgb()

) so I can save it in Datastore, how would I then convert the

Int

back to Jetpack Compose

Color

?

Does anyone know if there’s a way to disable the swipe away gesture on a ModalBottomSheetLayout? I can veto the change so that the sheet stays up, but id rather the user not be able to drag the content away in that case. why let them drag to dismiss if we’re just going to veto it anyway? A related question is that if i decide to allow a click outside or for them to swipe it away, is there a way to react that that?

Hi Team , Is it possible to use ConstraintLayout in Compose Multiplatofrm , i want to use for ios @etolstoy?

I'm trying to use kapt in my project and it is working well when I compile manually using maven. However, the Intellij IDEA integrated builder has trouble when compiling the generated sources. I've filed a bug to IDEA directly as I think the issue might be there (there's a simple reproducer project if anyone would be glad to look at it). To understand the issue more, I would like to know the reasoning behind and perhaps more details of this Maven/Kotlin guide that I followed. I noticed that when I don't "disable" the

maven-compiler-plugin

I get the same error during manual maven compilation ("package does not exist") as I get in IDEA when the pom is set up correctly. Can anyone shed more light into this issue?

Can we use lottie animations in compose KMM.
