Hello everyone, This is my 1st time with kotlin multiplatform. I’m trying to write and run unit tests for the android target. However I’d like those unit tests to be jvm only. For example, everytime, I try to run my tests, I have an emulator that is started. I’d like to avoid that and run them only in jvm mode. Is it possible?

Hi, bros, I found a bug in Android Studio : 1. Composite build cant reference shared library class in commonMain by Android Studio, but I can manually import the class into main project by writing

import com.xxxxx.xx.xx.X

  The android Studio doesn't tips you to do auto import classes Android Studio Version: 4.2 beta3 Gradle Version: 6.5 Kotlin Plugin Version : 1.4.21-release-Studio4.2-1 KMM Plugin: 0.2.0-release-65-Studio4.2 JVM: 15 Kotlin: 1.4.21 Can you guys understand what i mean? And how to let people to resolve this problem? I need this coding style with gradle composite build to Isolate the KMM build environment 😊

How to use GRPC on multiplatform

Hi guys. I’m trying to use ‘TrueTime’ pod in KMM and gradle sync keeps failing with the following error:

does anyone having problem after update Android Studio Arctic Fox Canary 5 (2020.3.1.5) ?

FAILURE: Build failed with an exception.

Hi all, I have a conceptual question. I want to provide a HTTP REST API Wrapper as MPP library. As far as I investigated

ktor

it does not manage async execution for me - the requests API is

suspend

based. So I think I have two options: A) Manage async execution by coroutines inside the common MPP code. From what I recall trying similar things a year ago, there are headaches configuring coroutine contexts for iOS and also some limitations (main thread only). So I am not sure if it all will work at all. B) Or, I can put async logic into platform code. More code but ok. But still, will I be able to call

suspend

marked methods from iOS? I'd like to have thoughts on this topic from more experienced folks.

Hi，guys, how i can solve this problem when i use cocoapod plugin to integrate into iOS project?

Anyone have a good .gitignore template for a kmp project?

Hello guys. After to update xcode to 12.4 version I am getting the following message error:

Building for iOS, but the linked and embedded framework 'shared.framework' was built for iOS Simulator.

In previous Xcode version that behaviour did not happened, I changed from simulator to real device and vice-versa so the packtoXCode executed again Did anyone see that already?

When depending on a KMP project module in an Android project, is there an idiomatic way to prevent the iOS target being compiled? This slows down development cycles in the Android Studio IDE and is wasted effort.

Hey, I am having trouble importing atomicfu to my project. I get compilation error when I try to add the common dependency. If I skip it, I get MethodNotFound crashes is my Android build. any ideas?

Hi, I wonder if there is somewhere an example with a multi module kmm project. I tried to split my ":shared" module into 2 modules, and it failed then, when I added a third module in a bottom layer with common architecture stuff in commun module. Any idea or link to help me ?

Is KMM plugin support for the latest Arctic Fox canaries planned?

With KMP Plugin in Android Studio. I am not able to add configuration for ios app. Is there anything I might be missing?

For multiplatform logging I could not find a library that had all the features I needed so I ended up writing one. Please check out KmLogging. Initially it supports Android, iOS, and JS. The features it implements is: • Uses platform specific logging on each platform: Log on Android, os_log on iOS, and console on JavaScript. • High performance. Only 1 boolean check when disabled. I like to put in lots of logging and want all of it turned off when releases and do not want to pay much overhead for having lots of logging. Also, when logging is on it needs to be really performant. • Extensible. Need to be able add other loggers such as logging to Crashlytics, etc. • Each logger can log at a different level. For example, you may only want info and above going to Crashlytics and all other loggers disabled in production. I would love to hear your feedback.

by the way of official ways, I cannot find any recent tutorial with compose, ktor, android plugin, clean or mvvm architecture with a github repository. Is difficult to set up, There is nothing constantly updated?

stringByAddingPercentEncodingWithAllowedCharacters

doesn’t work on Kotlin Native. My code is like following:

actual fun urlEncode(url: String) : String {
    val set = NSCharacterSet.URLQueryAllowedCharacterSet().mutableCopy() as NSMutableCharacterSet
    set.addCharactersInString("+&")
    return NSString.create(string=url).stringByAddingPercentEncodingWithAllowedCharacters(
        allowedCharacters = NSCharacterSet.URLQueryAllowedCharacterSet()
    ) ?: ""
}

My test code:

@Test
fun testUrlEncode() {
    assertEquals(
        "https%3A%2F%2Fmontageapps.com%3Ftoken%3Drth%26price%3Dinvaluable",
        urlEncode("<https://montageapps.com?token=rth&price=invaluable>")
    )
}

Test result:

kotlin.AssertionError: Expected <https%3A%2F%<http://2Fmontageapps.com|2Fmontageapps.com>%3Ftoken%3Drth%26price%3Dinvaluable>, actual <<https://montageapps.com?token=rth&price=invaluable>>.

Cannot create resource directory for android module in KMM shared module:

Hey guys, remember the library for coroutine wrappers created from annotations? It's now called Koru, I've fixed a few things about it and wrote an introductory article https://medium.com/futuremind/handling-kotlin-multiplatform-coroutines-in-swift-koru-4a80b93f232b. Enjoy 🙂

Would it be possible to uss KSP to freeze every object in its initialization? Our code is super fragile because we basically always need to remember to freeze all the objects we create or we see crashes on ios

Is there a way to check device’s network connection in common code or we have to write platform specific code? Are there any working examples?

Hi all. Super new guy here. I’ve started developing an app sharing code between iOS and Android. I’m having the hardest time getting an IDE setup that supports KMM and jet pack compose. My swift UI and common code is about 50% done but haven’t been able to work on Android UI because the ide gives me errors when I go to newest canary for Android studio. Any body have a working setup?

Hi all, I've been trying to call a method that takes a nullable Int in Kotlin common code from Swift. The method signature is:

suspend fun getEpisodes(page: Int?): EpisodePage

On the Swift side, have been try to write code but always am told:

Cannot convert value of type 'Int32' to expected argument type 'KotlinInt?'

This confuses me, and I'm sure there's a simple explanation. I can change the function signature to

getEpisodes(page: Int = 1)

instead, and that's much easier to deal with. So I'm curious what's going on here?

Are there any plans for KMM Android Studio plugin to start using CocoaPods integration when creating projects (https://kotlinlang.org/docs/native-cocoapods.html)?

Hey, does anyone know if Garmin OS (for their smart watches) works with Kotlin Native?

Hello all, I’m making some tests here with KMP multi-modules but I think I’m doing something wrong in terms of configurations. I’ve got: • KMP project (library) no 1 • KMP project (library) no 2 (makes use of library no 1) • Android/iOS app that use both libraries I can successfully compile each library individual. But when I try to import lib no1 intro lib no2 on Android Studio (via settings.gradle) I’ve got a couple of errors: • It’s unable to find buildSrc • It complains as not having any target defined (I’m using gradle 6.8.1 and plugin 7.0.0-alpha05) Any idea what I might be doing wrong?

Is it possible to ship non-code resources in a Kotlin multiplatform library? I assume not (yet?) because it’s tricky and unclear where they should end up depending on platform? Has anyone explored that?

Hey all 👋 I’m trying to adapt a Gradle plugin to KMP. I’m having a hard time accessing the classpaths of the various source sets/targets. I’m unsure if trying to access a classpath makes sense for native/js targets, but there should definitely be a way to access jvm/android classpaths. Am I the only one facing this? Do you have some examples or other plugins that might be doing this to share?

Is it possible to use Java code as part of an actual implementation in android/jvm source set? I have the Java class implemented and my code compiles, but at runtime the app crashes with

java.lang.NoClassDefFoundError: Failed resolution of: Lpackage/of/my/JavaClass;

I need to workaround a Kotlin/Java interop bug in a library where an enum is not accessible in Kotlin because it is part of a non-accessible parent class.

any known multiplatform http clients that don't use coroutines?
