Java 8 Language features supported in Android N: Lambdas

One of the new additions the Android N brings is support for several Java 8 language features: – Lambda expressions – Default and static interface methods, and – Repeatable annotations In this blog post we will take a look at the lambda expressions. Setting up development environment In order to start using these features however, the development environment needs some adjustments. The support of Java 8 language features requires a new compiler called Jack, which currently is supported only in Android Studio 2.1. So if you want to use Java 8 language features, you need to use Android Studio 2.1. Android documentation describes in details how to setup your development environment for Java 8 support. Enabling support for Java 8 To enable support for Java 8 in your Android project, the build.gradle file has to be adjusted by setting the compileOptions to version 1.8 and jackOptions enabled. android { ... defaultConfig { ... jackOptions { enabled true } } compileOptions { sourceCompatibility JavaVersion.
