How can I achieve

UNION

operator with Exposed DSL? I want to execute something like:

SELECT MAX(views) FROM (
    SELECT views FROM articles WHERE user_id = 1
    UNION ALL
    SELECT views FROM comments WHERE user_id = 1
) as writings

Is there any example out there using iOS/macOS

NSNotificationCenter

with Kotlin/Native?

Why

RoomDatabase.withTransaction

is defined in

RoomDatabase.android.kt

and not available commonly? Is the

db.useWriterConnection { it.immediateTransaction }

the way to go in shared code? It feels like a workaround, right?

Is there any way to ask run-time permissions for KMP projects ?

Why does

runTest

automatically advance until idle instead of pausing and letting the test advance the coroutine?

How to clean up data store after each test in unit tests? Using

@After
    fun tearDown() = testScope.runTest {
        testDataStore.edit {
            it.clear()
        }
        testScope.cancel()
    }

Getting error

Only a single call to

runTest

can be performed during one test.

As both the

test

method and

tearDown()

uses

runTest

I have an expectation for

Parcelable

and

Parcelize

in my KMP module defined like so:

expect interface Parcelable

@Target(AnnotationTarget.CLASS)
@Retention(AnnotationRetention.BINARY)
expect annotation class Parcelize()

and fulfilled on Android like so:

actual typealias Parcelable = android.os.Parcelable

actual typealias Parcelize = kotlinx.parcelize.Parcelize

This works well at runtime, however classes in the Android module that are themselves annotated with

kotlinx.parcelize.Parcelize

and have properties with types from the KMP module which are Parcelable/Parcelize cause an error to be shown in the IDE:

Type is not directly supported by 'Parcelize'. Annotate the parameter type with '@RawValue' if you want it to be serialized using 'writeValue()'

Does anyone know of a way to silence or suppress these errors? Or am I doing something wrong?

I have a question regarding how compose ios renders. Does it use its own rendering engine or does it compile to native SwiftUI elements? And what is the performance hit regarding compose ios? I imagine it does not have native performance, but how far from native it is?

I’m trying to send a broadcast command with

ProcessBuilder

. It “works”, but the output is different if I run the same command via terminal:

~ adb shell am broadcast -p com.sample -a sample.action -e "extra" "bla bla"

produces (correctly):

Broadcasting: Intent { act=sample.action flg=0x400000 pkg=com.sample (has extras) }
Broadcast completed: result=0

but the same command via

ProcessBuilder

produces:

Broadcasting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x400000 pkg= -p }
Broadcast completed: result=0

any idea why? 🤔

Does anyone know if there's a way to link a cinterop dynamic .so library from a relative path within the project? This workaround seems to only work for static libraries.
