Java 8 Language Features on Android (Android Development Patterns S3 Ep 9)
With Android Studio 3.0+ the default tool-chain includes support for many of these Java 8 language features and usage of the jack tool-chain is deprecated. Learn more here: https://youtu.be/LhaSi6_i2bo ---------------------------------------------------------------------- With the help of the Jack toolchain, you’ll be able to cut out boilerplate code with the help of some Java 8 language feature

Future of Java 8 Language Feature Support on Android
At Google, we always try to do the right thing. Sometimes this means adjusting our plans. We know how much our Android developer community cares about good support for Java 8 language features, and we're changing the way we support them. We've decided to add support for Java 8 language features directly into the current javac and dx set of tools, and deprecate the Jack toolchain. With this new dir

Everything about Java 8 – TechEmpower
The following post is a comprehensive summary of the developer-facing changes coming in Java 8. As of March 18, 2014, Java 8 is now generally available. I used preview builds of IntelliJ for my IDE. It had the best support for the Java 8 language features at the time I went looking. You can find those builds here: IntelliJIDEA EAP. Interface improvements Interfaces can now define static methods.
