Hello everyone, I'm trying to get a device id from both platforms however I'm having trouble with android. I can't seem to use the android sdk in the androidMain module. I've already set the sdk.dir in local.properties so I don't know if I'm missing something..

did you add the android plugin to your build file?

The default project template just sets up the android portion of an MP project as a jvm target. Use

fromPreset(presets.android, 'android')

and add the rest of the required standard android gradle config.

plugins {

id 'kotlin-multiplatform' version '1.3.40'

id 'kotlinx-serialization' version '1.3.40'

}

repositories {

google()

jcenter()

mavenCentral()

maven { url "<https://kotlin.bintray.com/kotlinx>" }

}

group "pt.fyi"

version "0.0.1"

apply plugin: 'maven-publish'

apply plugin: 'kotlinx-serialization'

kotlin {

def coroutine_version = "1.3.0-M2"

def ktor_version = "1.2.2"

def serializer_version = "0.11.1"

jvm(

)

iosArm64("ios") {

binaries {

framework()

}

}

sourceSets {

commonMain {

dependencies {

implementation "io.ktor:ktor-client-json:$ktor_version"

implementation kotlin('stdlib-common')

implementation "io.ktor:ktor-client-core:$ktor_version"

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core-common:1.3.0-M2'

implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime-common:0.11.1"

implementation "io.ktor:ktor-client-serialization:$ktor_version"

}

}

commonTest {

dependencies {

implementation kotlin('test-common')

implementation kotlin('test-annotations-common')

}

}

jvmMain {

dependencies {

implementation kotlin('stdlib')

implementation "io.ktor:ktor-client-android:$ktor_version"

implementation "io.ktor:ktor-client-json-jvm:$ktor_version"

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.0-M2'

implementation 'org.jetbrains.kotlinx:kotlinx-serialization-runtime:0.11.1'

implementation "io.ktor:ktor-client-serialization-jvm:$ktor_version"

}

}

jvmTest {

dependencies {

implementation kotlin('test')

implementation kotlin('test-junit')

}

}

iosMain {

dependencies {

implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime-native:$serializer_version"

implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-native:$coroutine_version"

implementation "io.ktor:ktor-client-ios:$ktor_version"

implementation "io.ktor:ktor-client-core-native:$ktor_version"

implementation "io.ktor:ktor-client-json-native:$ktor_version"

implementation "io.ktor:ktor-client-serialization-native:$ktor_version"

}

}

iosTest {

}

}

}

configurations {

compileClasspath

}

I have my targets defined as:

targets {
        final def iOSTarget = System.getenv('SDK_NAME')?.startsWith("iphoneos") \
                              ? presets.iosArm64 : presets.iosX64

        fromPreset(iOSTarget, 'ios') {
            binaries {
                framework {
                    baseName = "MyFramework"
                    freeCompilerArgs.add("-Xobjc-generics")
                }
            }
        }

        fromPreset(presets.android, 'android')
        jvm()
    }

This builds an iOS framework, an Android AAR and a java jar. I don't use the jar for anything except to run common tests quickly. You'll need to have an

android { }

section and to import the

com.android.library

plugin as well.

You should use an app instance id rather than a device/hardware id whenever possible.

The thing is that I cant seem to target for android.. note that in the source sets it appears only the common and iOS source sets. Also, if it matters in any way, note that in the folders the androidMain doesn't have the blue symbol

Did you add androidMain in your sourcesets?

yes I did
