How to show the software keyboard on composition (i.e. when a screen composable is first displayed)?

If I handle config changes manually (no activity recreation) and I want to override the system language the only way I’ve found is by using

updateConfiguration(config, displayMetrics)

, which works fine but happens to be deprecated 😅. All other ways that I know of rely on activity recreation (wrapping the context and using

createConfigurationContext

, using

attachBaseContext

, using

applyOverrideConfiguration

). Is there a non-deprecated way of doing this (without recreating the activity)? (I think overwriting the language is considered not being the best practice, but it is quite common and many clients want it 🤷‍♂️)

Hello! How to get current coroutine dispatcher?

Can anyone help? I am stuck with a

Ktor

Websocket

issue where the connection is non-responsive after receieving a push notification message from the server. The same code using

okhttp3.OkHttpClient

is fine. Details in the 🧵 below 👇:

Hi How to make Dialog scrollable in jetpack compose desktop because this not woking https://stackoverflow.com/questions/69683622/jetpack-compose-scrolling-in-dialog-gives-strange-effects

I’m getting bunch of weird looking crashes when I use

ComposeView

within my application. I’ve dug trough all the sources and still cannot find the cause od the problem. TLDR version of it is that I have a list with error view on top of it that contains “refresh” button. Clicking it with my internet off (so that the view will appear) makes my app crash with bunch of compose related logs that do not point in any direction such as:

java.lang.ArrayIndexOutOfBoundsException: length=3; index=3 -> ViewGroup
java.lang.IllegalArgumentException: Failed requirement -> androidx.compose.ui.node.MeasureAndLayoutDelegate
java.lang.IllegalArgumentException: Failed requirement -> androidx.compose.ui.platform.AndroidComposeView.notifyLayerIsDirty
java.lang.IllegalStateException: Underflow in restore - more restores than saves

Exception Type: Unknown (SIGSEGV)

What is important to mention is that it only happens on RELEASE version of the App. I’ve dissected my app and trying to reproduce the issue on fresh repo but I wasn’t able to, yet. No such problems when I switch to

ComponentActivity

instead of

Fragment

with

ComposeView

as its only view. I don’t have unusual amount of recompositions either - around 2 for state. Would appreciate any kind of help, guidance, ideas what might be the source of my problem.

How do I deactivate rules? I get a lot of false positives and therefore want to exlude some rules. I created a file named

.editorconfig

in the top level of my project with the contents

# Don't autoformat this file, IntelliJ adds forbidden spaces
root=true

[*.{kt,kts}]
disabled_rules=indent,max-line-length
insert_final_newline=true

But indent and max line length is still checked.

I am trying to use pixelcopy to capture the screen in a compose application, however, it asks for a view (which is kind of hidden in compose). What is the relationship between compose and views? How do I get the view currently being rendered by compose?

fun getScreenShotFromView(view: View, activity: Activity, callback: (Bitmap) -> Unit) {
    activity.window?.let { window ->
        val bitmap = Bitmap.createBitmap(view.width, view.height, Bitmap.Config.ARGB_8888)
        val locationOfViewInWindow = IntArray(2)
        view.getLocationInWindow(locationOfViewInWindow)
        try {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                PixelCopy.request(
                    window,
                    Rect(
                        locationOfViewInWindow[0],
                        locationOfViewInWindow[1],
                        locationOfViewInWindow[0] + view.width,
                        locationOfViewInWindow[1] + view.height
                    ), bitmap, { copyResult ->
                        if (copyResult == PixelCopy.SUCCESS) {
                            callback(bitmap) }
                        else {

                        }
                        // possible to handle other result codes ...
                    },
                    Handler()
                )
            }
        } catch (e: IllegalArgumentException) {
            // PixelCopy may throw IllegalArgumentException, make sure to handle it
            e.printStackTrace()
        }
    }
}

Hi there! I am running into a Jackson issue with sealed classes. I have the following code:

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME)
sealed class Principal
object AnonymousUser : Principal() {
  val _empty: String? = null
}

// other implementations of Principal

fun main() {
  // jacksonObjectMapper() is a function in jackson which creates an object mapper with the Kotlin module
  val input = jacksonObjectMapper().writeValueAsString(AnonymousUser)
  val principal = jacksonObjectMapper().readValue(input, Principal::class.java)
  println(principal)
}

This gives me the following error:

Exception in thread "main" com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "_empty" (class com.example.hellojavabin.graphql.context.Principal$AnonymousUser), not marked as ignorable (0 known properties: ])
 at [Source: (String)"{"@type":"Principal$AnonymousUser","_empty":null}"; line: 1, column: 49] (through reference chain: com.example.hellojavabin.graphql.context.Principal$AnonymousUser["_empty"])

What am I missing here? I also tried casting the input string directly to

AnonymousUser

but that fails with the same issue. Has anyone done something similar?

Hello, how do you debug multiplatform part of iOS projects? The official way to do that is using KMM plugin. However it has serious problem described here https://youtrack.jetbrains.com/issue/KT-56219/KMM-plugin-provide-an-arch-option-in-the-iOS-run-configuration.
