kotlinlang #multiplatform

I'm constructing a temporary Gradle plugin for using reflection across all platforms. Basically, it reads your code and creates KClass implementations for everything explicitly marked, which will be accessible through something like

MyClass::class.full

. Any suggestions/requests/interest?

<SOLVED> I'm having trouble getting Android Studio to recognize a module's dependencies (including the standard library) in my Gradle common project. It's odd - as far as I can tell, it's exactly the same as one of my other projects where that's all working great. Anybody have any helpful hints?

How is a Kotlin multi-platform library distributed/deployed ❔

Am I alone?

expectedBy

from

kotlin-platform-android'

seems to cause warning:

Warning:Configuration ‘compile’ is obsolete and has been replaced with ‘implementation’ and ‘api’.
It will be removed at the end of 2018. For more information see: <http://d.android.com/r/tools/update-dependency-configurations.html>

Even though I don’t know which line causes the trouble, but this is the only possible line. Anyway to fix this? Or maybe from other dependencies…

nm, this error happens with same code in plain jvm module. I get no errors in IDE though. This is going to be a tough one 🤦

Is there some step I'm missing to get

kotlin.test

unit tests in a common module to run in IDEA? The green arrows show up and seem clickable, but when I click them I get an error

No JDK specified

. If I change the common module's SDK to the JDK they will run, but this gets overwritten on any Gradle reimport. Will attach some details in a thread.

Noob android developer here. I have my kotlin multiplatform project which is currently being used in an iOS project via the framework that is generated by konan. What do i do if i want to use this in an android app? Do i generate a jar file and put it in the host app?

To expand on my above issue: In the android app where I am importing this jar file, I have 3 modules: A, B and C. B & C depend on A. The jar file is being imported into module A. Module B and A can see the types defined in the jar file, but module C cannot. Why would this be happening?

have the same issue. its annoying especially when all you want to do is add some constructors or methods with extra signatures in the

actual

implementation that differ based on each platform

markusa

is there a reason why I can't have

kotlin-test

as an

implementation

dependency in a common module?

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-common:$kotlin_version"
    implementation "org.jetbrains.kotlin:kotlin-test-common:$kotlin_version"
}

IntelliJ raises no error when using e.g.

assertEquals

, but Gradle says

Unresolved reference: test
Unresolved reference: assertEquals

etc, where the first error is on the import statement for

kotlin.test.*

Hi Friends, I am upgrading kotlin from 0.9.223 to 1.2.31. After upgrade i am getting an error since kotlin-time split into stdlib and stdlib-js. There is shared code used in JVM and JS modules. But having problem with compiling Date dataype. Since kotlin.js.Date works JS module and java.util.Date works in JVM module. can anyone please help me on this ? Thanks Selva

where is "master" of the Gradle plugin? is it in the
rr/kotlinx.serialization
branch of the kotlin repo? (this was supposed to go to #serialization)

Hi! Does anybody get work multiplatform projects with kts? Kotlin version 1.2.41

josephivie

Has anybody encountered a situation where the Android module in your common project has access to Android API 1 but nothing after that? The IDE says I have it, but when I compile it I get messages like "unresolved reference: MATCH_PARENT". No issues for things that were in API 1, though.

Ignoring common test and extending it with ios/android dummy runners works, but doesn't look like elegant solution

How do I use a kotlin-platform-android project (that is an android library itself) in an Android App (without deploying to a maven repo) ? It works out of the box with jars from kotlin-platform-jvm… help!

galex

06/20/2018, 7:35 PM

I am converted the koltin-platform-jvm one to android and I got the iOS part to build in Gradle but I have no idea how to use that project to develop a Custom View inside CLion (I guess we have to use that?)

First release of mutltiplatform and sqlite, with sqldelight driver. It's sort of at "take a look" stage, but is definitely functional: https://medium.com/@kpgalligan/sqlite-on-kotlin-native-9bcf47854cae

Hi, did anyone succeed in creating a multiplatform project using kotlin gradle scripts?

galex

06/23/2018, 1:53 PM

It seems to me that kotlin2js doesn’t convert to Javascript code that is not from its own module, correct? In that case how do we import code from a module (common-js) which implements the shared code between platforms (module common) ?

I lately have the problem (since I update to 1.2.50) that running speks sometimes do not pick up new code. I have checked "Delegate run/build to gradle". But it seems that not the code from gradle is taken up but some old code. Do others have this problem as well?

In a MPP setting, did you manage to build an iOS app with AppCode, or are you using Xcode? How do you work on the kotlin/native code (to have autocompletion, imports iOS kotlin classes, etc) ?

So.. suppose I have a lib written using just kotlin (I think) classes... what should I do if I want to make it available for JS? I plan to release it as a maven artifact and found some docs of how to do it... is there any problem if the kotlin/java plugins are applied together with the js plugins?

Is there a way to get the current call stack in Kotlin common code ? Something similar to currentStackTrace() on the JVM. I'd like to know the class and method name of the caller of a function. Thanks 🙂

Ruckus

Is there any plan to open up the multiplatform concept to let people create their own compile targets? Or even just some helpers for Kotlin transpiling (something like what is used for Kotlin/JS)?

Hi everyone, I’m trying to extract common code for my app’s data (models, basically just Kotlin data classes) and repository layers. 1/ I’d like to have the data layer available in iOS as a framework generated with Konan, and as a direct dependency in other platforms. I don’t have “expect” declarations there so maybe there’s a way to handle this without multiplatform? 2/ I’d like to share the repository logic (HTTP and Firebase) between the backend (Ktor/JVM), Android and later React JS apps. As I’m going to use specific libraries in each platform for HTTP and Firebase I want to use the expect/actual mechanism here. I’d also like to use Kotlin serialization and coroutines as much as possible. iOS will still have it’s own repository layer written in Swift until Multiplatform supports Kotlin/Native better. Does this make sense? Has anyone done something similar? How can I make the repository layer depend on the data layer? Thanks!

Yes this is possible and I have done it with the JVM, Android, and the web. I haven't tried out Kotlin Native and iOS yet as its still alpha.

It can be kinda tricky at first structuring your API to be able to adapt to each platform
