you can't. Android supports up to java 7. If you want to use AS only for Lambda, you can use gradle-retrolamba or retrolambda, which back-port retrolambda on java 6/7

Android supports Java 6 up to KitKat (4.4) with some minor syntactic sugar (like diamond operator), and Java 7 from there on (Lollipop and Marshmallow atm). Lambdas and other Java 8 stuff are available only as plugins (e. g. gradle-retrolambda or the original retrolambda). They will probably be included in API at some point in time (like Java 7 and KitKat), but it doesn't seem likely it'll be very soon.
