That is very little. As you say, rather trivial.
I want native code debugging, refactoring, static code analysis (Codan like), code navigation.
And for that you can easily use pretty much any other editor/IDE that supports that. You don't HAVE to use only Google's tools you know?
To my gradle file. I've set up a pretty simplistic JNI directory structure though. I can provide more info if this isn't enough as it's been awhile since I've set up a project from scratch.
