Kotlin extensions

[lub0s]

Why is the kotlin code without these extensions https://kotlinlang.org/docs/tutorials/android-plugin.html ? it would reduce your code a bit and make it more readable imo

Actually kotlin extension was already used.

dependencies {
    classpath 'com.android.tools.build:gradle:1.3.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"
}

The official page is outdated.

Then the "Find View" section needs to be updated to something like:

Kotlin

With Kotlin Android Extensions enabled (no extra dependencies needed):

val title = view.text1

(maybe mention the old way too, but as a fallback)
