Appium 1.18.0 查找元素花费的时间太长

Question

我正在使用 c# 和 Appium + Selenium 进行 Android 模拟器自动化，并遇到了一个挑战，即查找元素需要很长时间，我在设备上尝试过，它是相同的。有人可以帮我解决这个问题吗？

能力：

            appiumOptions.AddAdditionalCapability("deviceName", "emulator");
            appiumOptions.AddAdditionalCapability("platformName", "Android");
            appiumOptions.AddAdditionalCapability("platformVersion", "10.0");
            appiumOptions.AddAdditionalCapability("appPackage", "com.app");
            appiumOptions.AddAdditionalCapability("appActivity", "com.app.MainActivity");
            appiumOptions.AddAdditionalCapability("automationName", "UiAutomator2");
            appiumOptions.AddAdditionalCapability("app", ConfigReader.GetSetting("app"));

            //appiumOptions.AddAdditionalCapability("autoGrantPermissions", true);
            //appiumOptions.AddAdditionalCapability("allowSessionOverride", true);
            appiumOptions.AddAdditionalCapability("disableWindowAnimation", true);
            appiumOptions.AddAdditionalCapability("waitForQuiescence", false);

司机：

public static AndroidDriver<AndroidElement> _driver;
_driver = new AndroidDriver<AndroidElement>(new Uri("http://localhost:4723/wd/hub"), appiumOptions, TimeSpan.FromSeconds(300));

元素：

public AndroidElement Usernameinputbox => _driver.FindElementByAccessibilityId("username-IconInput");
Usernameinputbox.SendKeys(username);

根据Appium服务器日志，它花费了大量时间来寻找元素。输入用户名作为示例：

Answer 1

添加 appiumOptions.AddAdditionalCapability("fullReset", true); 后发现只有登录屏幕变慢，其他屏幕现在工作正常。

Answer 2

尝试减少超时值

 _driver = new AndroidDriver(_service, driverOptions.AppiumOptions);
 _driver.ConfiguratorSetWaitForSelectorTimeout(600);
 _driver.ConfiguratorSetWaitForIdleTimeout(100);
