Would you recommend using Retrolambda until it's supported? Cause it will be a huge loss of time if instant run isnt working... What do you think? – Chericheria

Is it known when Instant Run will become available for Jack? – Scaly

Its 2017 and still nothing. Shame on them. We spend more time worrying about IDE issues than our coding problems themselves. – Davinadavine

Jack is no longer required. Built-in support is added with default tool-chain in androidstudio.googleblog.com/2017/04/… – Tanyatanzania

Answer 2

Patience is a virtue. Support for Java 1.8 will be built in Android studio without the need of any configuration or external libraries in the near future (weeks from now)
