So I did a tiny thing in the repo:

https://github.com/adamdruppe/d_android/tree/master/android-dub-test

if you open that in android studio it should load up, and the 
makefile is commented, but tells you the 8 commands (4 dub 
builds, 4 file copies, just doing the same things for each of the 
4 android architecture targets) to do a full add.

The main program is still in Java - there's a way to do pure D, 
the NDK's NativeActivity, but I never tried it personally (tbh 
I've only actually done hello world in android at all, i have 
zero interest in mobile dev, i just did it cuz someone had to do 
something and the JNI meta code was kinda cool) - but then you 
can call to/from D/java with native methods.

no kidding, I spent several weekends just trying to understand 
the setup and build process. And I still basically don't really 
know, which is why my thing there builds the D code externally 
and copies the files where gradle can find them instead of 
actually changing the gradle config.
