Android native debug compiled with externalNativeBuild.ndkBuild

I want to debug native code in Android Studio (version 2.2) in following examples: https://github.com/googlesamples/android-ndk/tree/master-ndkbuild.

I have tried to edit app Run/Debug configuration and change debugger type to native or hybrid without success. Also tried to attach debuger selecting hybrid or native, but app doesn't stop on breakpoint in C++ code, when debugger is connected to process.

I have bigger project which is built simillary to linked examples. Currently rebuilding makefiles is not possible, therefore I want to run debugging with this kind or project setup. This kind of project setup means; using externalNativeBuild with ndk-build.

Does anyone know how to debug these examples?

In application's build.gradle:

buildTypes {
    debug {
        debuggable true
        initWith debug
        jniDebuggable true
        externalNativeBuild {
            ndkBuild {
                cFlags "-DDEBUG=1"
            }
        }
    }
}

cFlags is optional, but useful. It's not described in official Google docs, i found it in Android Gradle plugin DSL docs

Works on Android Studio 2.2.2+

Unfortunetly AS + gradle + ndk-build doesn't support debugging from IDE. The solution is to rewrite buildscripts to cmake.
