Introduction

When we are talking about Android development, immediately language that comes to our mind is:Java

Almost all the android apps are written in Java only, Do you think Java is the only option?

Answer is No,You can write Android apps in any language that can compile and run on the Java Virtual Machine (JVM). And one JVM-compatible programming language that’s really caught the attention of the Android community is Kotlin, a statically typed programming language from JetBrains.

Note:In Google I/O 2017, Google has announced that Kotlin is the another official language for Android Developemnt.
Kotlin is not the replacement of Java or it will not replace java. Java and Kotlin will work together. 
Kotlin + Java = Powerful Java

What is Kotlin?

1) Kotlin is a statically-typed language, developed by JetBrains, that runs on the Java virtual machine and also compiled to JavaScript source code.

whose syntax is more expressive and concise than that of Java. With features like higher-order functions, lambda expressions, operator overloading, string templates, and more

Kotlin has a lot more to offer than Java. Because Java and Kotlin are highlyinteroperable, they can be used together in the same project.

What is Statically- typed language?

Dynamically typed programming language do type checking at the run-time as opposed to compile-time. A programming language is said to use static typing when type checking is performed during compile-time as opposed to run-time. In static typing types are associated with variable not values.
