运行appium test for Android时获取代理错误

Question

Environment
- java client build version : 6.1.0 
- Appium server version : 1.7.1 
- Desktop OS/version used to run Appium if necessary: Windows 7 
- Node.js version : 6.4.1 
- Mobile platform/version under test: Android/ 8.1.0 
- Real device or emulator/simulator: Real device 
- Selenium Version: 3.12.0
- TestNg Version : 6.14.3 

当我为android运行appium测试时，无法在实际设备上启动应用程序，在appium日志中发现代理错误，在控制台中发现错误，无法创建新会话。

是否需要任何网络设置，如果是，请指导需要设置哪种设置。

public class launchApp {
AndroidDriver<WebElement> driver;

@BeforeClass
public void beforeClass() throws MalformedURLException, InterruptedException {
    DesiredCapabilities capab = new DesiredCapabilities();

    capab.setCapability("deviceName", "Redmi Note 5");
    capab.setCapability("udid", "35924c6f0804");
    capab.setCapability("platformName", "Android");

    capab.setCapability("appPackage", "com.miui.calculator");
    capab.setCapability("appActivity", "com.miui.calculator.cal.CalculatorActivity");
    driver = new AndroidDriver<WebElement>(new URL("http://0.0.0.0:4723/wd/hub"), capab);

     Thread.sleep(5000);
}

@Test
public void m1() throws InterruptedException {
    System.out.println("kfd");
    Thread.sleep(2000);

}
}

确保您使用的是最新的Appium server 1.9.1。

安装了最新的Android SDK和ADB。

卸载您的应用程序，应用程序设置和解锁应用程序从您的设备。

我今天也遇到了这个错误。

经过分析，我发现我连接的设备不知怎么脱机了。

我使用以下命令进行了检查：

$ adb devices
