Integrating OpenCV with Android: JNI Implementation and Library Usage

DESCRIPTION

This guide details the steps to integrate OpenCV with an Android application using JNI (Java Native Interface). It covers the transformation of OpenCV source code to be used as a dynamic library in Android. The process includes building OpenCV sources, implementing necessary C/C++ header files (`jni.h`), and linking binary objects for seamless integration. Additionally, it explains the use of the built library with a focus on `CvCamera`, ensuring efficient use of OpenCV functionalities within an Android environment.
