Interesting to see that the "Tasks" of the Android library are pretty similar to JS Promises, and the Futures and Promises of frameworks like Akka. All of which do help simplify and structure concurrent code.

There are people trying to play with Akka and Scala for Android as well, though it's an awkward fit: Scala's run-time library is large enough to strain size limits on an Android app. (On older versions of Android, pre-Jellybean, you need to have Proguard evict unused methods and classes just to get something small enough to fit.)

That said, using with the tools of more modern JVM-based languages can tighten up your code in all sorts of ways. An experiment along those lines is here:

It's not limited to Scala though.

Google copied the limits of their .dex file format from Java .class files, except that the limit is (of course) per class in Java, while it is per application on Android.

People could have expected that they didn't do something this stupid, but hey, saving two bytes per .dex file was more important I guess.

They still haven't fixed this. The thing fixed in Jellybean was a different bug in their code where they didn't deduplicate parent interface types.
