Appium和Android Studio

Question

我已经在ubuntu上安装了Appium，并在android studio中使用java命令进行了第一次测试，但在运行测试时出现了一个错误

无法创建新会话。（原始错误：请求一个新会话，但一个正在进行中）（警告：服务器没有提供任何堆栈跟踪信息）命令持续时间或超时： 603.92秒

public class MyTest {

    AndroidDriver driver;

    @Before
    public void testCaseSetup()throws  Exception {
        //service.start();
        //reader.readFile();
        DesiredCapabilities cap = new DesiredCapabilities();
        cap.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");
        cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Nexus_5");
        cap.setCapability(MobileCapabilityType.PLATFORM_VERSION, "5.0.2");
        cap.setCapability(MobileCapabilityType.APPIUM_VERSION, "v1.4.7");
        cap.setCapability(MobileCapabilityType.APP_PACKAGE, "com.example.nitish.myappium");
        cap.setCapability(MobileCapabilityType.APP_ACTIVITY, ".MainActivity");
        driver = new AndroidDriver<MobileElement>(new URL("http://0.0.0.0:4723/wd/hub"), cap);
    }


        @Test

        public void testcase1()throws  Exception
        {
            driver.findElement(By.id("com.example.nitish.myappium:id/front")).click();

        }

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


}

Answer 1

此错误意味着服务器seeion已经存在端口4273尝试更改服务器端口号，并在代码中给出相同的端口号

driver = new AndroidDriver<MobileElement>(new URL("http://0.0.0.0:**4723**/wd/hub"), cap);

Answer 2

请尝试此代码段

@Before
public void setUp() throws MalformedURLException {

    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability("platformName", "Android");
    capabilities.setCapability("VERSION", "5.0.2");
    capabilities.setCapability("deviceName", "Device Name");
    capabilities.setCapability("appPackage", "com.example.nitish.myappium");

    capabilities.setCapability("appActivity", "ui.activity.SplashScreenActivity");

    driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

}
