| // 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 { | |
