I am trying to add both Dlib and superpowers libraries to my android project using Android.mk. I included successfully prebuilt shared Dlib library (.so files) using Android.mk, but when I am trying to add the superpower as a static library (the package has .a files and CMakeLists.txt), I am facing issue regarding liking JNI functions with java. I cannot use the JNI functions in java. I would appreciate it if someone can help me. Here is my Android.mk file:
