android-retrofuture is a backport of the Java 8 CompletableFuture API upgraded to the current Java 9 (JEP 266) enhancements for Android developers wanting to use the Android Studio 3.x D8 / desugar toolchain.
There is nothing specific to Android or the desugar toolchain in this code (it could even be compiled to Java 6 bytecode) but it has a dependency on android-retrostreams which is why this exists as a separate component (the corresponding streamsupport-cfuture component can't be used with android-retrostreams and android-retrostreams itself can only be used with desugar or Java 8 and higher).
Other than having a different package name this code has no further changes compared with streamsupport-cfuture
The new Java 12 exception handling methods for CompletableFuture JDK-8211010 have been integrated in release 1.7.0
