You can freely use all of the existing tools in Android Studio with your Kotlin code.

Android Studio provides excellent support for Kotlin.

you can use the best practices of functional programming (higher-order functions, lambdas, anonymous functions, function references).

Null safety is implemented on the level of type system.

OOP in this programming language is just so richer than in Java.

Kotlin is a great fit for server-side development.

Besides, again, Kotlin 1.1 supports Java 8.

Kotlin and Java are 100% compatible: you can combine the existing Java code with Kotlin code, use Kotlin classes in the Java code and vice versa.

yes, it is possible to use Java 8 for Android, which is awesome, but in fact Java 8 is far less “tasty” than Kotlin, IMHO.

as I mentioned earlier – Google announced their full support for this open source programming language and approved Kotlin for Android development, which means that all optimization/compatibility things that JetBrains did before, they now do in collaboration with the Google team.

So what are the benefits of Kotlin vs Java and why should your next project be implemented specifically using Kotlin? Here’s my list of advantages:

I decided to learn Kotlin and review it here from the development perspective.

The advanced Android community sighed with relief – from now on it was possible to make all current and new projects in the Kotlin programming language without looking back at Java and with no fear that Google will interfere. At first glance it all seemed suspicious, but we all know what happened at Google IO 2017 – Kotlin was given green light by the Google themselves, along with the fullest support for Kotlin and approval.
