Android KTX is an extension library for writing shorter and cleaner Android code in Kotlin

As developers, it's almost always desirable to be able to write shorter and more readable code without sacrificing performance, stability, or control.

JetBrains Releases v1.0 Of Kotlin, A Smart JVM-Compatible Language That Can Be Used To Write Android Apps

Kotlin has been emerging as a programming language to keep a close eye on. It started as an internal project at JetBrains back in 2011 and was released early the next year. Taking inspiration from both classic C-based languages and a number of modern alternatives like Scala, Kotlin is branded as a "pragmatic" language and modeled to encourage smarter coding and easier readability.
