Where are obj files for ndk-stack in androidTest packages

Question

I'm implementing a few instrumented tests for a module (which is packaged in a aar archive, not apk) library I'm working on. The module is written partially in Java and partially in C.

Sadly a crash is occurring while running my tests and executing native code; I want to symbolicate the crash dump with ndk-stack in order to see the actual culprit and investigate my problem.

I know that those files should be in the object directory obj/, right inside the project directory, specifically:

$PROJECT_PATH/obj/local/<ABI>

The problem is that they simply aren't there. Where are they? How can I let the androidTest related tasks generate them or showing me where they are? What am I missing?

The project structure is the following:

MyProject
 |_ :app (a single button application which integrates the library)
 |_ :myLibrary (the actual library I'm working on and testing)
    |_ java
    |  |_ my.package.name
    |  |_ my.package.name (androidTest) <- a test here crashes
    |  |_ my.package.name (test)
    |_ cpp
       |_ my native files

After the discussion in the comments it appeared that the correct path to find debug object symbols is:

$PROJECT_PATH/myLibrary/build/intermediates/ndkBuild/debug/obj
