我一直在观看许多youtube视频以及以下与Appium，Selenium和Android应用自动化有关的教程。但是我仍然不确定我的代码有什么问题，我是编程的新手，所以我不知道如何解密所有这些信息。
这是我的代码：
package testcase;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import org.openqa.selenium.Capabilities;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Test;
import io.appium.java_client.android.AndroidDriver;
public class OpenOfferUp {
@Test
public void OpensOfferUp() throws MalformedURLException
{
File OfferUp = new File("C:/Users/boung/Desktop/offerupapk");
DesiredCapabilities cap = new DesiredCapabilities();
cap.setCapability("deviceName", "Virtual Device");
cap.setCapability("platformName", "android");
cap.setCapability("app", OfferUp);
cap.setCapability("appPackage", "com.offerup");
cap.setCapability("activityName", "com.offerup.android.activities.SearchActivity");
AndroidDriver driver = new AndroidDriver(new URL("http://localhost:4723/wd/hub"), cap);
}
}
这就是控制台中显示的内容

答案 0 :(得分：0)
问题出在功能app上。您应该为.apk文件提供绝对的本地路径或远程http URL。但是您插入一个File对象。
cap.setCapability("app", "C:/Users/boung/Desktop/offerupapk");
请注意，如果您的Webdriver Hub服务器在远程计算机上，则必须先将.apk复制到那里。
