Is it planned to support NDK development in Android Studio or IntelliJ IDEA?

We have recently announced that we’re starting work on an IDE for C++, and we plan to eventually support NDK development as part of that effort. As for NDK development support in Android Studio, Google hasn’t announced anything so far.
