is anyone here familiar with using KodeIn in their multiplatform projects?

I’m having an KMP project with many kmp modules inside, I’m facing weird behavior when I edit something in module

A

, the changes aren’t reflected directly in another module

B

that consumes it. Also when I try to navigate from

B

to

A

it takes me to the

.jar

file of this module. Has anyone had similar problems?

anyone worked with C inerop on both iOS and Android through KMP? are there some docs or something I can follow?

Is there a way to run .java tests in a kotlin MPP? I am trying to test that my Java interop interfaces are correct. (Things like @JvmStatic @JvmOverloads.) I can't seems to get them running in jvmTests directory. Perhaps I should just add tests to a separate Java project?

I would use that set to filter this:

targets {
    presets
        .filterIsInstance<AbstractKotlinNativeTargetPreset<*>>()
        .filter { it in supportedTargets }
        .forEach { preset ->
            targetFromPreset(preset, preset.name) {
                compilations["main"].source(sourceSets["nativeMain"])
                compilations["test"].source(sourceSets["nativeTest"])
            }
        }
}

What is the best practice for testing common code on Android? In my Kotlin MPP the

allTests

task runs tests only on iOS (specifically a task called

iosSimTest

). If you write Android specific tests they run on android successfully by running the task called

testDebugUnitTest

. I cannot figure out how to run the common test cases on Android. Am I supposed to run them on JVM and it is not possible to run on Android? I currently do not have a JVM target set up since it is an iOS/Android project only.

Hi folks! I’m Anastasiia, product manager in Kotlin Multiplatform team and I have a funny question for you today 🙂 Have you had cases when strict memory model in Kotlin/Native actually helped you find potential (or real) bugs in Kotlin/JVM part of your Multiplatform project? If yes - please, leave ➕ reaction under that message. I’d like to ask you a couple of questions about your case in direct messages. Thanks! p.s. If you’d like to share your story in thread - it’s fine too 🙂

I’m splitting out a KMP project into multiple feature/layer modules and perhaps I don’t have my Gradle dependencies setup correctly, but dependencies seem pretty slow to update. For example, in the graph

A

->

B

->

C

Changing an interface in

C

isn’t reflected in

A

or

B

as in a JVM project. Some combination of reimporting, invalidating, etc will get it working again, but I haven’t narrowed down the correct workflow. Has someone experienced and/or solved this?

Hi everyone. I am using kotlin multiplatform to generate android libraries. what is the best way to debug it though. Currently, I have to build the .jar file, put it in the android app and run the android app to see the log statements. Is there any better way to do it?

Hello, having Android studio IDE errors but builds are working fine.  Here's the structure: Repository1 is composed of • Android module

:library

• A Kotlin MP module targeting iOS and Android.

:core

. • The Android module

:library

is dependent on

:core

. In

build.gradle (library)

, I added

api project(":core")

to the dependencies. Repository2 is composed • Android App

:app

• Common Kotlin MP module targeting iOS and Android

:common

• The

:app

is dependent on

:library

. In

build.gradle (app)

I added

implementation linkto:Library

• The

:common

module is dependent only on

:core

. In

build.gradle (common)

I added

api linkto:core

. The build works fine but I am getting this IDE error: "Cannot access class X, Check your module classpath for missing or conflicting dependencies". X is a class in

:core

Any idea on how to solve this as the IDE errors are very annoying... Kotlin 1.3.72

I am not able to load files using File() from java.io in my kotlin multiplatform project. It compiles fine but when I include the build .aar file in my android project, it gives no such directory exists error. Is it not possible to load a file in a KMP project?

I've seen some open discussion on it but not a clear yes or no answer. Does Kotlin built using a gradle file support conditional compilation? We're investigating using this technique, https://medium.com/dont-code-me-on-that/aspect-oriented-programming-in-kotlin-95ff8598913, for supporting annotations that will allow us to do simple call count mocking for some of our objects but we want to make sure that that code is not present in either JS, Android or iOS code on release builds.

Trying to upgrade coroutines so i can use StateFlow stuff and getting a

Unresolved reference: MutableStateFlow

compile error in my kmp module. Anybody else seen this? The IDE resolves it no problem

Hello! Is anyone encountering issues when using

combine

on flows with K/N? My code works on Android but on iOS it doesn't run the

combine

block. Any help would be greatly appreciated!

Hey good morning everyone. I just started a new job. Their codebase is written entirely in Java. The have several shared Java libraries, which are used for the iOS (using j2objc), Desktop and Android apps. I’d like to slowly begin converting these to Kotlin. Is it possible to create a Multiplatform project and import the old Java project(s) into it? Or is there a better solution?

Is there an example anywhere of using source annotationRetentions in a multiplatform project? I'm trying to follow this, https://medium.com/@elye.project/annotation-tutorial-for-dummies-in-kotlin-1da864acc442, but it presumes a non-multiplatform project and i'm running into a wall where my annotation module needs to be multiplatform but the processor module can likely not be. When you do that though you get the warning stating that the java processor module can't depend on the android annotation one.

Does anyone know if there is a recommended way to unit test SQLDelight common code on Android? You need an android context for the sql driver. Should I use instrumented unit tests or Roboelectric? Is there some other better way?

what version of kotlin serialization should i be using with Kotlin 1.4-M2? I've got 1.4-M2 for the plugin and 0.20.0 for the common, jvm and js part, but it's failing to compiling saying it can't find kotlinx import

plugins {
    val kotlinVersion = "1.4-M2"
    kotlin("multiplatform") version kotlinVersion
    kotlin("plugin.serialization") version kotlinVersion

hi guys I am new to kmp I am trying to work on a sample project, I was planning to use coroutines. I need to understand how can I implement

<http://dispatchers.io|dispatchers.io>

in iosMain. 🙏

The KMP gradle plugin doesn't support jetpack compose. Any work around apart from using the id("kotlin-android")?

Hi All, m new to KMP, facing some issue... I have used expect/actual classes... but when i extracted the generated aar for android, the actual class is missing, i still see expect class in the classes.jar... Not sure what i am missing.. Appreciate if someone can help me?

Is there a way to automatically fix names for Js? Like

fun `hello world`()

I have to set

@JsName

manually

For implementing a date object in KMP is the best solution so far to make a "expect class" with full implementation on each platform?

This message was deleted.

Hi, Do you know if we have something like

System.getenv()

jvm method but that works for

js

and

native

as well?

When trying to run unit tests in IntelliJ it says "no tasks available". A solution I found was to set the tests to run with IntelliJ instead of gradle. This runs them but now its failing to load resources from the ClassLoader which is needed for some of the tests. When I run the tests via gradle script it appears to work properly. Does any of this sound like known issues, any workarounds? Trying to convert a jvm library to KMP but need to get the basics working before doing any major refactors to more into common.

@e5l I try to move my OSX project to 1.4-M2 and 1.3-1.4-M2 With this code

val kotlinVersion = "1.4-M2"
    val ktorVersion = "1.3.2-1.4-M2"
    sourceSets {
        commonMain {
            dependencies {
                implementation(kotlin("stdlib-common"))
                implementation("io.ktor:ktor-client-core:${ktorVersion}")
    }.  }.  }

I have error

e: Could not find "io.ktor:ktor-io-cinterop-bits" in [/Users/atomin/Documents/iq/xpoint-sdk, /Users/atomin/.konan/klib, /Users/atomin/.konan/kotlin-native-prebuilt-macos-1.4-M2/klib/common, /Users/atomin/.konan/kotlin-native-prebuilt-macos-1.4-M2/klib/platform/macos_x64].

I try to add

val macosMain by getting {

                implementation("io.ktor:ktor-client-core:${ktorVersion}")
            }

Hey, anyone know of a way to detect if you are running your tests on Android device or JVM?

Hello all. Does anyone have a link to a large gradle android/ios mpp project? Most samples are rather small. I'm looking for something that has multiplatform modules depending on other multiplatform modules?
