Solution
    • Use the latest version of Kotlin (>= v1.1.51)
    • Use the latest version of Kotlin Android Extensions in your app module, so your build.gradle may look like:
    apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
   androidExtensions {
     experimental = true
   } 
}

dependencies {
  // ...
}
