The lack of any public direction on this from Google to Android developers has been annoying me for a while now. It seems like Android has decided to be stuck on Java 6 forever.
I'd love to see them really shake things up in Android by, eg, going with NaCL/PNaCL (or even something like seccomp2, don't really care) to manage sandboxing and exposing an API framework (so apps can present common UI widgets) with a C API (regardless of what it is written in underneath) making it relatively easy to consume from any language. Write your Android app in Go, Python, Java, whatever you want, as long as it has API bindings! But I'm not holding my breath on that.
