I had the same problem, and after going crazy for hours, the only solution I found was to use android studio 3.2 and use the following configuration:

Android studio 3.2

KOTLIN PLUGIN: Version: 1.2.60-release-Studio3.2-1

Android studio preferences --> Kotlin compiler LANGUAGE VERSION: 1.2 API VERSION: 1.2

build.gradle (project)

buildscript {
    ext.kotlin_version = '1.2.60'
    ext.anko_version='0.10.5'
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0-alpha05'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'io.fabric.tools:gradle:1.+'
    }
}

build.gradle (Module: App)

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation "androidx.lifecycle:lifecycle-extensions:2.0.0-rc01"
    kapt "androidx.lifecycle:lifecycle-compiler:2.0.0-rc01"
    implementation "org.jetbrains.anko:anko:$anko_version"
    implementation "org.jetbrains.anko:anko-coroutines:$anko_version"
    ...more.....

If you're comfortable with Canary builds, you can still use Android Studio 3.3 Canary Build 5. The errors occur when using the Canary Build 6 and Gradle Alpha 6.

Also experiencing the same problem. IDE was throwing some errors though I haven't really changed my code, except for the necesaarybuild.gradle to match Gradle dependencies (Alpha 6).

To add, Context.alert functions to do not seem to work as well.

Same error...

I fixed it by downgrading my build.grade dependencies to 'com.android.tools.build:gradle:3.2.0-rc01'
