Android Marshmallow - calling a library module (native library) from another library module

Question

I have 3 modules in my application with the name (for example) "application" , "emp-library" , "face-library" .

application - contains only the loading screen and opens the library activity emp-library .

emp-library . This is a library module and contains the basic form of the employee and the camera module to get the image of the employee, and the image will be transferred to the face-library . > for face detection.

face-library . This is a library module and contains a face recognition library for face detection (own library - own face detection algorithm).

The app works on Lollipop devices . But when I run the application in Marshmallow , it becomes broken with the exception below.

Fatal signal 11 (SIGSEGV), code 2, fault addr 0xdeadbaad in tid 32696

Note. This is the only error message I received in the logs.

Is there any specific library build required for Marshmallow devices ? Please help me solve this problem?

Updated:

-> Since I can not find any technical error (as far as I know, I did not get any exception in my own code), I followed the trial and error method.

- > face-library app ( ). NOT CRASHED.

- > , face-library emp-library ". .

- Marshmallow (face-library) ( emp-library)?
