// This file is part of OpenCV project.
// It is subject to the license terms in the LICENSE file found in the top-level directory
// of this distribution and at http://opencv.org/license.html.
//
// Notes about integration OpenCV into existed Android Studio application project are below (application 'app' module should exist).
//
// This file is located in <OpenCV-android-sdk>/sdk directory (near 'etc', 'java', 'native' subdirectories)
//
// Add module into Android Studio application project:
//
// - Android Studio way:
// (will copy almost all OpenCV Android SDK into your project, ~200Mb)
//
// Import module: Menu -> "File" -> "New" -> "Module" -> "Import Gradle project":
// Source directory: select this "sdk" directory
// Module name: ":opencv"
//
// - or attach library module from OpenCV Android SDK
// (without copying into application project directory, allow to share the same module between projects)
//
// Edit "settings.gradle" and add these lines:
//
// def opencvsdk='<path_to_opencv_android_sdk_rootdir>'
// // You can put declaration above into gradle.properties file instead (including file in HOME directory),
// // but without 'def' and apostrophe symbols ('): opencvsdk=<path_to_opencv_android_sdk_rootdir>
// include ':opencv'
// project(':opencv').projectDir = new File(opencvsdk + '/sdk')
//
//
//
// Add dependency into application module:
//
// - Android Studio way:
// "Open Module Settings" (F4) -> "Dependencies" tab
//
// - or add "project(':opencv')" dependency into app/build.gradle:
//
// dependencies {
// implementation fileTree(dir: 'libs', include: ['*.jar'])
// ...
// implementation project(':opencv')
// }
//
//
//
// Load OpenCV native library before using:
//
// - avoid using of "OpenCVLoader.initAsync()" approach - it is deprecated
// It may load library with different version (from OpenCV Android Manager, which is installed separatelly on device)
//
// - use "System.loadLibrary("opencv_java4")" or "OpenCVLoader.initDebug()"
// TODO: Add accurate API to load OpenCV native library
//
//
//
// Native C++ support (necessary to use OpenCV in native code of application only):
//
// - Use find_package() in app/CMakeLists.txt:
//
// find_package(OpenCV @OPENCV_VERSION_MAJOR@.@OPENCV_VERSION_MINOR@ REQUIRED java)
// ...
// target_link_libraries(native-lib ${OpenCV_LIBRARIES})
//
// - Add "OpenCV_DIR" and enable C++ exceptions/RTTI support via app/build.gradle
// Documentation about CMake options: https://developer.android.com/ndk/guides/cmake.html
//
// defaultConfig {
// ...
// externalNativeBuild {
// cmake {
// cppFlags "-std=c++11 -frtti -fexceptions"
// arguments "-DOpenCV_DIR=" + opencvsdk + "/sdk/native/jni" // , "-DANDROID_ARM_NEON=TRUE"
// }
// }
// }
//
// - (optional) Limit/filter ABIs to build ('android' scope of 'app/build.gradle'):
// Useful information: https://developer.android.com/studio/build/gradle-tips.html (Configure separate APKs per ABI)
//
// splits {
// abi {
// enable true
// universalApk false
// reset()
// include 'armeabi-v7a' // , 'x86', 'x86_64', 'arm64-v8a'
// }
