Issue setting up Appium + Java + Android Studio [Solved]

Hi guys.
I’m totally new with Appium, apologies if I write something too wrong…

I am struggling to set up Appium + Java + Android Studio:
I have installed Appium and can run the server and the GUI client, I can connect a device, launch an app, get its components… No issues here.
However, when setting up Android Studio, I am having issues importing some libraries. I have downloaded:

  • java-client 7.0.0 with io.appium Group ID (Maven Central Repository Search)
    Files:

    java-client-7.0.0.jar

  • Selenium driver (for Java, 3.141.59, Downloads | Selenium)
    Files:

    byte-buddy-1.8.15.jar
    commons-exec-1.3.jar
    guava-25.0-jre.jar
    okhttp-3.11.0.jar
    okio-1.14.0.jar

In Android Studio, I create a basic project, then copy the jar files to the ‘libs’ folder in the ‘app’ folder displayed when in the ‘project’ view. The files are displayed in Android Studio. Then, I selected them and added as libraries to the ‘app’ module’. After rebuilding the project, the files are added to app\build.gradle as dependencies. No errors are returned so far.

Then, I create a new java class (right click in src>main>[project name] ) and added the code displayed in the Appium Inspector after connecting and tapping around the app:

import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;
import junit.framework.TestCase;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import java.net.MalformedURLException;
import java.net.URL;
import org.openqa.selenium.remote.DesiredCapabilities;

public class SampleTest {

  private AndroidDriver driver;

  @Before
  public void setUp() throws MalformedURLException {
    DesiredCapabilities desiredCapabilities = new DesiredCapabilities();
    desiredCapabilities.setCapability("automationName", "UiAutomator2");
    desiredCapabilities.setCapability("platformName", "Android");
    desiredCapabilities.setCapability("deviceName", "any");
    desiredCapabilities.setCapability("appActivity", "com.myapp.testapp.MainActivity");
    desiredCapabilities.setCapability("platformVersion", "7.1.1");
    desiredCapabilities.setCapability("udid", "18123432A62");
    desiredCapabilities.setCapability("fullReset", false);
    desiredCapabilities.setCapability("appPackage", "com.myapp.testapp");

    URL remoteUrl = new URL("http://localhost:4723/wd/hub");

    driver = new AndroidDriver(remoteUrl, desiredCapabilities);
  }

  @Test
  public void sampleTest() {
    (new TouchAction(driver)).tap(735, 353).perform()
  }

  @After
  public void tearDown() {
    driver.quit();
  }
}

Issues:
These dependencies cannot be resolved in Android Studio:

import junit.framework.**TestCase**;
import org.junit.**After**;
import org.junit.**Before**;
import org.junit.**Test**;
import org.openqa.selenium.**remote**.DesiredCapabilities;

The list of jar files look much smaller that some installations guides I have seen in the internet, but these are really old, from around 2016. I have downloaded the files several times and also previous versions and the files are the same ones.

Any help will be really appreciated.
Thanks

The client-combined-3.141.59.jar library have to be added to the project too.
