mavenCentral
to your project'sbuild.gradle
file's repositories section if not already present.
repositories {
mavenCentral()
}
- Add either the normal or contributions version in the dependencies of your module.
// opencv
implementation `com.quickbirdstudios:opencv:VERSION`
// opencv with contributions
implementation `com.quickbirdstudios:opencv-contrib:VERSION`
}
- Initialize OpenCV before using it.
if (!OpenCVLoader.initDebug())
Log.e("OpenCV", "Unable to load OpenCV!");
else
Log.d("OpenCV", "OpenCV loaded Successfully!");
βΌοΈ Want to use OpenCV as source Dependency?
- Checkout the Repository. There will be an empty project with placeholder for the opencv source.
- Download the source from your desired release.
- Unzip the folder. The name of the folder will be
opencv_VERSION
oropencv-contrib_VERSION
. Copy this folder to the project and keep it at the same level as theapp
folder. - Open
settings.gradle
and replace the VERSION with the OpenCV version you have downloaded.
// Remove/comment out the one you aren't going to need
include ":opencv_VERSION"
include ":opencv-contrib_VERSION"
- Open app/build.gradle and replace the VERSION with the OpenCV version you have downloaded
// Remove/comment out the one you aren't going to need
implementation(project(":opencv_VERSION"))
implementation(project(":opencv-contrib_VERSION"))
- Sync and run the project. You should see the screen with the text
OpenCV Loaded Successfully
.
