Answer 1

• 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 {
  // ...
}

Answer 2

For Using of Kotlin parcelize you have to follow these steps:

1- Add this line into your Gradle:

apply plugin: 'org.jetbrains.kotlin.android.extensions'

2-Enable android Extensions in your Gradle too :

 androidExtensions {
        experimental = true
    }

That's it. But be aware that you have added apply plugin: 'kotlin-android-extensions' in your gradle too if you didn't before.

The plugin has since been updated to 'kotlin-android-extensions' as mentioned by @SML, i.e. You no longer need following apply plugin: 'org.jetbrains.kotlin.android.extensions' – Subir

Just add this line in build file classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
