java - 尝试运行 appium 但应用程序自动关闭并显示错误

Question

我是新来的 appium 并尝试打开 android 模拟器的设置。我已经安装了 appium 1.21.0 并使用 android studio 创建了一个测试用例。测试完成后，我看到的是它关闭了应用程序。我在 android 模拟器中运行该应用程序。nmnfmds kjbsfjkhdsd hkjhf jkshfjkhs kbkjfsd kjbsdfjkb kjbkjsd。

这是我的MainActivity.java文件

import org.openqa.selenium.remote.DesiredCapabilities;

import java.net.MalformedURLException;
import java.net.URL;

import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;

public class MainActivity {
    static AndroidDriver<MobileElement> driver;
    private static URL url;

    public static void main(String[] args){
        openpi();
    }


 public static void  openpi(){

      DesiredCapabilities cap = new DesiredCapabilities();

      cap.setCapability("deviceName","sdk_gphone_x86");
      cap.setCapability("platformName","Android");
      cap.setCapability("udid","emulator-5556");
      cap.setCapability("platformVersion","11");
      cap.setCapability("appPackage","com.android.settings");
      cap.setCapability("appActivity", "com.android.settings.homepage.SettingsHomepageActivity");
      cap.setCapability("appWaitDuration","2000");


     try {
         url = new URL("http://127.0.0.1:4723/wd/hub");
     } catch (MalformedURLException e) {
         e.printStackTrace();
     }
     driver = new AndroidDriver<MobileElement>(url, cap);
 }
    }```
