在模拟器上运行自动化代码时出错

• 无法通过使用appium和android studio自动化模拟器并获得以下错误。

我使用下面的java代码来自动化应用程序。

我的代码

package com.example.sample;

public class FirstTest {

    WebDriver driver;

    @Before
    public void setUp() throws MalformedURLException {       
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("deviceName", "Nexus 6P API 25");
        capabilities.setCapability(CapabilityType.BROWSER_NAME, "Android");
        capabilities.setCapability(CapabilityType.VERSION, "7.1.1");

        driver = new RemoteWebDriver(new URL("http://127.0.0.1:5000/wd/hub"), capabilities);
        driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
    }

    @Test
    public void testFirstCalculator() {
        driver.findElements(By.xpath("//android.widget.Button")).get(0).click();
        driver.findElement(By.name("7")).click();
        driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
    }

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