Hello Author,
first of all, this forum is for development of OCCT itself, not for questions related to using it. So you will unlikely receive replies from other OCCT users here. User forum is located here:

Concerning, Android Studio, we have experience for building OCCT-based projects using it, but JNI sample in OCCT is not yet updated for it. You are welcome to our support services if you are interested in finding solution.
