Any help is much appreciated!

I moved out the externalNativeBuild outside of buildTypes and have put it under android. It started working.

android {
....
...
   buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            debuggable true
            minifyEnabled false

            ndk {
                abiFilters   "armeabi-v7a", "x86"
                moduleName "HelloJNI"
            }
        }
    }

    externalNativeBuild {
        ndkBuild {
            path "src/main/jni/Android.mk"
        }
    }

    buildTypeMatching 'debug', 'release'
...
....
} // end of android
