Question

When I try to add IntArrays in my codes, the Android Studio gives me these errors:

Most codes works fine. I can test some projects. Emulator is working fine too. But when it comes to add IntArrays it cannot compile. I've search on everywhere but I couldn't find the solution. I've reinstalled the Android Studio and JRE but it didn't work as well.

Used Codes:

package com.example.test2

fun main(){
    var a:IntArray = intArrayOf(1,2,3,4)
    println("test")
}

My build Gradles:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.3.61'
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

and the second one is:

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 29
    buildToolsVersion '29.0.2'
    defaultConfig {
        applicationId "com.example.test2"
        minSdkVersion 15
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.core:core-ktx:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'

}

Addition: I have tested this situation in a completely different computer. It gives an error too. I guess it is kind a bug of Android Studio.

I had the same problem and I discovered that this is a bug of Kotlin library. (I am so serious.) You cannot call intArrayOf() method.

I am sure that you are using Windows 10 Single Language Turkish. (I was using the same operating system.) Kotlin's some libraries cannot work on Turkish operating system. You can check this issue on YouTrack.

You can solve your problem with installing Windows 10 Pro English or Windows 10 Single Language English. I do not know any other approach right now. (You can open new issue on Kotlin website.)

This bug took from me 30 days. You can check my related question about this Kotlin bug.
