I've took OpenCV Library and exported it as .aar library. Now you can easily use OpenCV in a Gradle / Android Studio project.
I've uploaded the .aar in my maven repository. You only need to add following lines to your build.gradle to add the dependency:
repositories {
maven { url "https://dl.bintray.com/blazei/maven" }
}
dependencies {
implementation 'org.opencv:opencv-android:3.+'
