Update: Beginning with Android Studio 2.4, the Jack compiler will be deprecated and Java 8 Support will be integrated in the default build chain. Some Java 8 features are available on any API level, some are still limited to API >= 24, see:

Old answer:

The Java 8 features are available beginning from API level 9, but only if you use Android Studio 2.1 (preview) and the Android N Preview SDK

Improved Java 8 language support - We’re excited to bring Java 8 language features to Android. With Android's Jack compiler, you can now use many popular Java 8 language features, including lambdas and more, on Android versions as far back as Gingerbread. The new features help reduce boilerplate code. For example, lambdas can replace anonymous inner classes when providing event listeners. Some Java 8 language features --like default and static methods, streams, and functional interfaces -- are also now available on N and above. With Jack, we’re looking forward to tracking the Java language more closely while maintaining backward compatibility.
