// 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'])
|
|

// 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_java3")" 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
|
