how include TestNG to Android Studio in AndroidTest

I have a some tests for android using Android Studio with jUnit. It is work. But, now i need use testNG. I have been include testng library

dependencies {
   ... 
   androidTestImplementation 'org.testng:testng:5.14.2' 
   implementation group: 'org.sonatype.http-testing-harness', name: 'testng-runner', version: '0.8'
   ... 
}

After, I create test with TestNG annotations. But i can't run the test.

import com.example.gallyamovrifat.autotesting.Page.RolloutPage;

import org.testng.annotations.*;
import androidx.test.uiautomator.UiDevice;
import androidx.test.uiautomator.UiObjectNotFoundException;

import static org.testng.Assert.assertEquals;
import static org.testng.AssertJUnit.assertTrue;

public class RolloutKeysDownload {
    private UiDevice device;
    private RolloutPage page;
    private final String ROC_ADDRESS = "****************";
    private final String USER_NAME = "****************";
    private final String PASSWORD = "****************";

    @BeforeClass
    public void SetUp(){
        device = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());
        page = new RolloutPage(device);
    }

    @Test
    public void enterRolloutCenterAddress() throws UiObjectNotFoundException {
        page.authorizationButtonClick();
        String verifyAddress = page.enterRocAddress(ROC_ADDRESS);
        assertEquals("Сертификат подтвержден", verifyAddress);
    }

    @Test
    public void authorization() throws UiObjectNotFoundException {
        boolean isAuthorized = page.joinButtonClick();
        if (!isAuthorized) {
            isAuthorized = page.authorize(USER_NAME, PASSWORD);
            assertTrue(isAuthorized);
        }
    }
}

I get exception:
