Kotlin

Kotlin

Kotlin is a JVM based language created by JetBrains, the team behind IntelliJ, which is the base for Android Studio. It´s an object oriented language that includes many ideas from functional programming. Kotlin was born with the idea of covering those gaps Java leaves and add much more simplicity to the code saving us from writing as much boilerplate code as possible. Kotlin is one of the many JVM based languages that are starting to emerge as a possible Java successor in Android development.

FEATURES

Relatively fast learning curve: compared to Scala for instance, we are moving in a much simpler scope. Kotlin is much more limited, but it´s easier to start if you´ve never used a modern language before.

Lightweight: Kotlin library is small compared to others. This is important because Android method limit is always a problem, and though there are some options to solve it such as proguard or multidexing, all of these solutions will add complexity and will be time consuming when debugging.

Highly interoperable: It works extremely well with any other Java libraries, and the interoperability is very simple.

Perfectly integrated with Android Studio and Gradle: we have one plugin for the IDE and another one for Gradle, so it won´t be difficult to start an Android project using Kotlin.
