I'm in aw of how powerful it could be... but its confusing. Like the Kotlin Multiplatform plugin creates this template... why has it proven so difficult to add android and iOS as source sets? Its as if Multiplatform plugin doesn't have them or something.

You need to add some extra setup for Android. Apply the

com.android.library

plugin, add a top-level

android{}

block with sdk version config, add a manifest file.

Like this right?

plugins {
    java
    id("com.android.application")
    kotlin("android")
    kotlin("multiplatform") version "1.3.71"
}

yeah

Plugin [id: 'com.android.application'] was not found in any of the following sources: BLANK

Where's that repositories block? Needs to be either in

buildSrc

of a parent build.gradle, or in

pluginManagement

of settings.gradle

its in the top level build.gradle.kt file above the kotlin {...}

That article is two years old so without reading it I can promise you it gets some details wrong

Its really the only one I could find that really tried to explain it.

We've been maintaining this sample at Touchlab that might be helpful for config: https://github.com/touchlab/KaMPKit

ok, i'm starting to think the google() repo is being blocked on my internet... why I can't even download the those plugins I suspect. I suspect I'm gonna want to avoid android studio and develop in intellij

Check if you can build KaMPKit. It has a pretty good out-of-the-box configuration. If that doesn't work, maybe it's your internet. If it does then there's something wrong with your configuration

alright, I'll give that a try.. thanks for the extra gobys I never saw those.

Also if you want more up-to-date tutorials there's some codelabs that Jetbrains is maintaining now https://play.kotlinlang.org/hands-on/overview

Ah yes, been thru many already... still need to learn cooroutines

The other project has jvm and js if that helps

The KampKit is time saver. To start from scratch or check how something is done or test something. It’s really great!

Ok great.. question, do I have to have the android app in that app folder?

I’ve seen some example using another folder but more than often the android app is inside the app folder. Like a convention

Ok, thanks... yeah I'm not a fan of mashing these conventions together... every target should get its aptly named folders... js/jvm/ios/android... without this basic ability to organize architectures I'd be losing important abilities.

There are 2 things here. Code specific to the Android app will be under the app folder and shared code with some Android specific will be under something like ´shared/src/androidMain’

Yeah, trying to setup a complete project structure like this. I hate having these spurious files and folders liying around... even the .idea and .gradle folders pissed me off for a while... thank fully they start with a dot so stay out of my way up top... but when I'm programming for any target I want to either stay in that targets srcDir the entire time or the common folder.... Maybe the it sounds like the app and iOS folders should go in the build folder? I don't really understand why they are need in addition to the androidMain and iOSMain folders

The project setup you show me doesn’t have any iOS or Android app. Only shared framework that will be used in some other apps.

I dont understand why the folders are needed, cant an entire simple hello world android app be built and gradle automated with all code inside the src/android folder and all output inside the build folder?

It’s really to have the shared code and the Android app in 2 folders. To separate everything. It’s like you have 3 projects inside the same repo. One Android app, one iOS app and a shared library

Okay, that's what I thought... it just makes no sense so my engineering brain cant accept it...lol

Kotlin multiplatform is not for all UI related stuff

Hmmm... that makes sense I guess... okay then... I'll rework everything and trust in the system...

I did a personal project using KMP and working on a new work project with it

I don't know man, this seem impossible. Can't seem to find anything when I start trying to bring android into this project. I keep rolling back to when my project was just js/jvm/common and then trying again to merge in android stuff... over and over again I keep failing... same kind of basic errors, can't find anything. Using default examples and modernizing when needed. Is it possible that js/jvm and android need different versions of gradle or something?

That error comes from the root

build.gradle.kts

and I think it’s not where you want to add

implementation

I upgraded to gradle 6.3, no idea how I was running on 5.2 something... you all are running 5.6.2 apparently. Also I had to comment out the clean task and I remove the android and android-extension plugin from this app build file.

plugins {
    id("com.android.application")
    kotlin("android")
    kotlin("android.extensions")
}

After doing all that the below screenshot is what I ended up with... everything looks pretty solid to me except the app build file disappeared, something automatically deleted it... will try to add that back now. Okay, I added the example gradle app build file to my project, I know it won't work but I am just testing the plug black because that's what is causing this. first thing I noticed is the:

id("com.android.application")

seems to be importing ok, which is great it wasn't before. But it keeps failing on this common error I saw before implying the android and, as previously, android-extensions is failing to download:

Plugin [id: 'org.jetbrains.kotlin.android'] was not found in any of the following sources:

And yet, I have app and shared tasks in my gradle ingtellij plugin, but only when I remove the app gradle file with nothing but... yeah, okay, app everything works when the app file has nothing but

plugins {
    id("com.android.application")
}

But fails when it has:

plugins {
    id("com.android.application")
    kotlin("android")
}

IML files are necessary for IntelliJ. It’s possible to hide them I think. Check in the options

Yeah, I think I'm going to have to set this up as two isolated projects... js/jvm/common and ios/android/common, those are the only templates that make sense to me and every method I've studied for combining em seems rube goldberg-ish

This is only a library for iOS and Android. It does not contains app. And starting from here, it’s pretty easy to add JS

ah, your saying that is only for making librarsies... okay that makes sense. I still think I shouldnt have to put the manifest files in main, in androidMain instead and I should be able to store imls externally like before... and I think I should be able to move the iOS and Android folders inside the Main folders... move everything in shared folder up a level and delete shared, move build script into common... I'd be happier with that structure. shared is for making libraries? I guess that makes sense, and main is needed to run it locally, makes wierd and ugly sense I guess... its all just so dam ugly and inflexible

The manifest is required if you want the library to be used in Android app. And iOSMain et androidMain folders are mostly used to store

actual

declarations

All makes sense... just ugly compared to my impossible vision... I'll proceed with the template, trying to merge it into my project and understand as I go
