Can't import some packages in JavaCV

[Tamada]

I'm trying to create a facial recognition app based on this example(https://github.com/bytedeco/javacv/blob/master/samples/OpenCVFaceRecognizer.java) and using javacv 1.5.x, but some imports don't work. Here problems with those imports:
import org.bytedeco.javacpp.BytePointer;
import org.bytedeco.javacpp.IntPointer;
import org.bytedeco.javacpp.DoublePointer;

import static org.bytedeco.opencv.global.opencv_core.*;
import static org.bytedeco.opencv.global.opencv_face.*;
import static org.bytedeco.opencv.global.opencv_imgcodecs.*;


I decided to figure it out then, to start with an example(https://github.com/bytedeco/gradle-javacpp/blob/master/samples/javacv-demo/src/main/java/org/bytedeco/javacv/samples/Demo.java) using gradle-javacpp, to take imports from there, but they don't work either. In this case i have problem with following packages:
import static org.bytedeco.opencv.global.opencv_core.*;
import static org.bytedeco.opencv.global.opencv_imgproc.*;
import static org.bytedeco.opencv.global.opencv_calib3d.*;
import static org.bytedeco.opencv.global.opencv_objdetect.*;


Also I don't have packages displayed inside org.bytedeco.opencv. So there is a problem and with these imports as well

import org.bytedeco.opencv.opencv_core.*;
import org.bytedeco.opencv.opencv_imgproc.*;
import org.bytedeco.opencv.opencv_calib3d.*;
import org.bytedeco.opencv.opencv_objdetect.*;

Adding dependencies there won't add them to your Android project. You'll
need to add them to app/build.gradle as per the instructions here:
