Please I need some help with MotionLayout I have tried a lot but it’s seems futile. I handle my recycler view visibility programmatically , it’s tied to loading from network and all that. However, when OnSwipe I have an header I’m trying to animate. I have added visibilityMode and set it to ignore on both start and end. But for some reasons it still doesn’t display. If I set the layout properties on the scene it displays but then the animation doesn’t work, more like it does it very fast regardless of the duration

Hello, I'm having a problem with polymorphic serialization with discriminator in request. When I try to serialize object my discriminator is not being added. I'm using ktor 1.5 and kotlinx serialization I'm gonna write mock classes to mimic my classes here:

@Polymorphic
@Serializable
abstract class Base {

    @SerialName("property_1")
    abstract val property1: String

    @SerialName("property_2")
    abstract val property2: String
}

private const val DISCRIMINATORA = "5"

@Serializable
@SerialName(DISCRIMINATORA)
data class A(

@SerialName("property_1")
    override val property1: String,

@SerialName("property_2")
    override val property2: String,

@SerialName("propertyA")
    val propertyA: String,

) : Base()

private const val DISCRIMINATORB = "4"

@Serializable
@SerialName(DISCRIMINATORB)
data class B(

@SerialName("property_1")
    override val property1: String,

@SerialName("property_2")
    override val property2: String,

@SerialName("propertyB")
    val propertyB: String,

) : Base()

My koin definition is

single {
    APIClient(baseUrl, get())
}

val polymorphicBaseRequestModule = SerializersModule {
    polymorphic(Any::class) {
        subclass(A::class)
        subclass(B::class)
    }
    polymorphic(Base::class) {
        subclass(A::class)
        subclass(B::class)
    }
}

single {
    HttpClient(OkHttp) {
        install(JsonFeature) {
            serializer = KotlinxSerializer(kotlinx.serialization.json.Json {
                isLenient = true
                ignoreUnknownKeys = true
                classDiscriminator = "hello"
                serializersModule =  polymorphicBaseRequestModule
            })
        }
}

My Request class is

abstract class APIRequest<ReturnType : Any>(
    open val httpMethod: APIHTTPMethod = APIHTTPMethod.Get,
    open val contentType: String? = null,
    open val resourcePath: String = "/",
    open val urlParameters: HashMap<String, Any?>? = null,
    @Polymorphic
    open val httpBody: Any? = null
)

My API client is

suspend inline fun <reified ReturnType : Any> send(apiRequest: APIRequest<ReturnType>): Result<ReturnType> {
    val builder = HttpRequestBuilder()
    builder.url.protocol = URLProtocol.HTTP

    builder.url.host = baseUrl
    builder.url.encodedPath = apiRequest.resourcePath

    builder.method = HttpMethod.parse(apiRequest.httpMethod.value)

    // Add headers
    apiRequest.contentType?.let {
        builder.headers.append("Content-Type", it)
    }

    // Add request body
    apiRequest.httpBody?.let { httpBody ->
        builder.body = httpBody
    }

    Sentry.addBreadcrumb("Resource path: " + apiRequest.resourcePath)

    return withContext(<http://Dispatchers.IO|Dispatchers.IO>) {
        try {
            Result.success(client.request<ReturnType>(builder))
        }catch(e) {
            Log.d("error", e.response.content)
        }
}

What am I doing wrong?

when I try and create a SparseArray, like this:

var array = SparseArray<ByteArray>(1)

...array ends up being empty (it shows as

“null”

in the debugger, and if I do this:

array.setValueAt(0, byteArrayOf(byte)

val value = array.get(0)

...then

value

is

null.

Hello all,is there any channel where I can ask Google ML textRecognition related question?

Anyone have any experience with overlapping elements in jetpack compose? i.e. a button with a badge icon

https://jakewharton.com/a-jetpack-compose-by-any-other-name/ Anyone have more information about this? this is very interesting and I cant find more sources about the topic

hey guys I would be grateful if anybody could help me. I added gradle plugins in

settings.gradle.kts

like this:

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
    }

plugins {
        id(GradlePluginId.GRADLE_PLUGIN) version GradlePluginsVersion.GRADLE_PLUGIN
    }

}

that

GradlePluginId

and

GradlePluginVersion

are Kotlin objects, but the problem is they don't resolve with just this message: _*Unresolved reference: GradlePluginId Unresolved reference: GradlePluginVersion*_ however I can go to declaration and back to usage through the IDE. my project settings:

implementation("com.android.tools.build:gradle:4.1.1")
distributionUrl=<https://services.gradle.org/distributions/gradle-6.5-bin.zip|https://services.gradle.org/distributions/gradle-6.5-bin.zip>

thank you.

Im using an NotificationListenerService for snoozing certain notifications on condition X by calling snoozeNotification(id, duration). When condition X changes during the snooze periode, how do you 'unsnooze' such a notification?

Hey guys! So, I have been trying out Navigation Components. Created an activity with 2 fragments. A goes to B on button press and B has a button to go back to A by destroying current fragment. Now the issue is on this B to A fragment. If I use

binding.button2.setOnClickListener {
            activity?.supportFragmentManager?.popBackStack()
        }

On going back to A, if I use A to B button again, app will crash with this message:

java.lang.IllegalArgumentException: navigation destination dev.theimpulson.myapplication:id/action_firstFragment_to_secondFragment is unknown to this NavController

However, if I use this in B to A button:

binding.button2.setOnClickListener {
            activity?.onBackPressed()
        }

App doesn't crashes anymore. Any ideas why?

Hi! I have a custom parceler

class StringSrcParceler : Parceler<StringSrc?>

Which I use like this:

@Parcelize

  val forbidDismissWithMessage: StringSrc?,
) : Parcelable

At runtime this gives me an exception:

Hi all. I’m no Android dude, but debugging an Android issue that requires me to open a webview and input my credentials. Problem is, my external keyboard is not usable from within the webview. Works fine in the app itself (outside of the webview). Anyone having similar experiences and a possible solution?

what is this even for it everyone keeps getting told to go to stack overflow?

Hi, I have created a android library project that uses kotlin dsl for gradle and android studio doesn't identify any module or anything from that project. I can't use basic things like finding declarations for classes or auto add imports and auto correct variable types. I may as well just open this project in notepad...

Anyone else suffering from https://issuetracker.google.com/issues/176138645 when using navigation component, any workarounds?

Hello! I'm wondering if anyone with some experience with Koin could elaborate on the differences between the AndroidX package

org.koin:koin-androidx-viewmodel:$koin_version

versus just the basic

org.koin:koin-android-viewmodel:$koin_version

. I have been using the latter with ViewModels from the AndroidX lifecycle package and everything is working just fine. What would I need the AndroidX Koin dependency for?

Hi guys, does anyone have an example gradle config of MPP library including android target?

is it a good idea to wrap Activity Result api into coroutines? so instead of

val getContent = registerForActivityResult(GetContent()) { uri: Uri? ->
    // Handle the returned Uri
}
getContent.launch("image/*")

we could use something like

val getContent = registerForActivityResult(GetContent(), suspendableContract)
val result = getContent.launchSuspendable("image/*")

Looks like there is a bug in

com.android.tools.build:gradle:7.0.0-alpha05

- switching to this version from

alpha04

on my project produces the error

lateinit property variantName has not been initialized

. I'm running a 'standard' Kotlin Multiplatform / Mobile gradle setup.

Hello everyone, I started working to create a Kotlin Multiplatform project. But I am facing a problem in integrating ViewModel in the project. I want to use moko-mvvm library if I use the current version (

0.9.1

) it is not being imported in the shared module. Instead, if I change the version to

0.6.0

I can import it but I get this error

Cannot access 'dev.icerock.moko.mvvm.viewmodel.ViewModel' which is a supertype of 'com.example.vmdemo.shared.GreetingViewModel'. Check your module classpath for missing or conflicting dependencies

. I really appreciated it if someone could help me to solve this issue, thanks in advance.

Is KMM is same as flutter like create two application with single code or iOS part has to be done in swift using Xcode

Does anyone know where is AGP version mapping to build tools version? I have a CI docker image with 30.0.2 build tools, and the latest stable AGP 4.1.2 only uses 29.x.y.

Does anyone know when the jetpack compose gonna release the stable version?

For anyone using In app Updates -> Is update priority working for you?

I'm working through a tutorial that includes:

rollButton.text = "Let's roll!"
        rollButton.setOnClickListener {
            Toast.makeText(this, "button clicked", Toast.LENGTH_SHORT).show()
        }

I know the first line would be:

rollButton.setText("Let's roll!");

in Java. Why doesn't the next statement become the following in Kotlin:

rollButton.onClickListener = ...;

Using one linear recyclerview, when I update the list data lets say from meters to centimeters and calling notifyDataSetChange() on adapter afterwards, it changes/shuffles the position of items(edittexts inputs for numbers) in recyclerview. How can I prevent the list from shuffling and retaining the same position for converted items? Is Diffutill recommended for this to work?

Hi all, does anyone know a good tutorial that explains how a view can be created programmatically. I have managed to create a view (EditText) however, I cannot set the layout_height or layout_width to anything other than MATCH_PARENT or WRAP_CONTENT. Also, I would like to add a scrollbar with minLines and maxLines. However, none of them appears to work even though they work in the XML resource file.
