java - 收到意外响应 : {"code" :"ECONNRESET"} when executing appium script in android emulator

Question

我正在运行以下脚本:这段代码是在android模拟器中打开PlayStore

DesiredCapabilities capabilities = new DesiredCapabilities();

        capabilities.setCapability("deviceName", "Nexus 5 API Q");
        capabilities.setCapability("automationName", "UiAutomator2");
        capabilities.setCapability("udid", "emulator-5554"); 
        capabilities.setCapability("platformVersion", "10");
        capabilities.setCapability("platformName", "Android");
        capabilities.setCapability("appPackage","com.android.vending");
 capabilities.setCapability("appActivity","com.google.android.finsky.activities.MainActivity");
//        capabilities.setCapability(MobileCapabilityType.APP, fs.getAbsolutePath());
        capabilities.setCapability("noReset", "true");

        try {
            AppiumDriver<MobileElement> driver = new AndroidDriver<>(new URL("http://0.0.0.0:4723/wd/hub"), capabilities);

        } catch (MalformedURLException e) {
            System.out.println(e.getMessage());
        }
    }

我的appium-doctor显示所有最新内容，但在appium服务器上我收到错误: [Appium日志] https://www.dropbox.com/s/s0mros5scj4mikx/Screenshot%202019-05-27%2018.25.26.png?dl=0添加了完整的 appium 服务器日志。

我使用的是 Java 11 和 appium 1.13

Answer 1

从模拟器中卸载 uiautomator-server 和 uiautomator-server-test 应用，然后尝试再次运行脚本。

在命令提示符中运行以下命令来卸载应用程序:

adb uninstall io.appium.uiautomator2.server
adb uninstall io.appium.uiautomator2.server.test

然后运行您的自动化脚本。当我收到 ECONNRESET 错误时，这对我有用。
