android-retrostreams is a fork of the streamsupport library targeted at Android developers who want to take advantage of Android Studio 3.0 desugar toolchain's capability to use interface default & static methods across Jar file boundaries.
Utilizing this feature of desugar, the streamsupport API can be even more aligned with the original Java 8 / 9 API exposed in the java.util.function and java.util.stream packages. That allows for Android app's code to be much more in accordance with the standard Java 8 / 9 usage than it is now possible with the original streamsupport API (which is bound by the restrictions of supporting Java 6).
With respect to static / default interface methods the android-retrostreams public API should now be identical to the Java 9 API wherever this is possible (i.e. for all interfaces that have first been introduced in Java 8).
Supplemental helper classes, public static methods and so on that served as a replacement for the
default / static interfaces methods in the original streamsupport API are now mostly gone.
E.g., no j8.u.s.RefStreams class anymore - all these methods are now in the j9.u.s.Stream interface.
The online Javadoc gives a picture of the API changes.
The current stable release is android-retrostreams-1.6.1.
