如何解决Webview上下文更改导致Appium崩溃时，无法在Device Farm中的混合应用程序上启动测试
我正在开发React Native应用，我需要在Device Farm上启动测试。使用我的Android模拟器在本地进行的测试工作非常好。但是，在Device Farm上启动它们时，它会崩溃并且不会启动任何单个测试。
我的应用程序使用Webview登录，并且Webview在应用程序启动后立即启动。我的能力是这样的：
{
platformName: 'Android',maxInstances: 1,automationName: 'UiAutomator2',appPackage: "com.init.app",appActivity: ".MainActivity"
}
我在chromedriver版本上遇到了问题，我在外部安装了很多软件包，然后我最终使用了Device Farm提供的chromedriver，就像我在论坛的另一篇文章中看到的那样。我没有chromedriver错误，但测试最终失败并显示以下错误：

我使用AWS Device Farm提供的Appium 1.18，并且我的应用程序在Android 8+上运行。
