        }
    }
    dependencies {
        classpath "gradle.plugin.org.golang.mobile.bind:gobindPlugin:0.2.7"
    }
}
apply plugin: "org.golang.mobile.bind"
gobind {
    pkg = "github.com/your_name/your_repo"
    GOPATH = "/your/go/path"
    GOARCH = "arm 386" // important
}

• Or using gomobile bind command (generate .aar)

gomobile bind -target android/arm,android/386

Runtime dependency

• Don't forget copy opencv/opencv-libs/libs/* to /AndroidStudioProject/app/src/main/jniLibs/

If not, you may get error message that go library can not find the opencv_java.so

opencv/opencv-libs/libs/armeabi/libopencv_java.so
opencv/opencv-libs/libs/armeabi-v7a/libopencv_java.so
opencv/opencv-libs/libs/mips/libopencv_java.so
opencv/opencv-libs/libs/x86/libopencv_java.so

• If still not found the opencv library, try this

System.loadLibrary("opencv_java");
