Why no toast and async?

[speedcell4]

My Gradle file like this

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "lambdell.fileio"
        minSdkVersion 21
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    compile 'org.jetbrains.anko:anko-sdk23:0.8' // sdk19, sdk21, sdk23 are also available
    compile 'org.jetbrains.anko:anko-support-v4:0.8' // In case you need support-v4 bindings
    compile 'org.jetbrains.anko:anko-appcompat-v7:0.8' // For appcompat-v7 bindings
    compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4'
}

buildscript {
    ext.kotlin_version = '1.0.0'
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"
    }
}
repositories {
    mavenCentral()
}

But when I typed toast in MainActivity, it got red. Is there something wrong with my gradle file?

I had the same issue. Specifying org.jetbrains.anko:anko-sdk23:0.8.2 instead of just 0.8 did the trick

@anakin78z Thank you, that works for me~
