无法从本机切换到 WEBVIEW_chrome，显示异常：io.appium.java_client.NoSuchContextException
Unable to switch from native to WEBVIEW_chrome showing exception : io.appium.java_client.NoSuchContextException
我正在真实设备上测试网络应用程序并使用 Chrome 浏览器，我尝试设置集合，我得到了 NATIVE_APP 和 WEBVIEW_chrome 但是当我尝试切换到WEBVIEW_chrome 使用 driver.context() 方法抛出异常io.appium.java_client.NoSuchContextException:io.appium.java_client.NoSuchContextException: 处理命令时发生未知服务器端错误。原始错误: 未知服务器-处理命令时出现端错误。原始错误：未知错误：无法将端口转发到设备 18e6bebc:。未知错误：adb 命令失败。额外响应：<>。
请帮助我，自上两周以来我一直在苦苦挣扎。提前致谢。
我已尝试 amazon.in 的功能和测试脚本如下：
private static AndroidDriver<WebElement> driver = null;
@BeforeTest
public void initConfig() throws MalformedURLException, InterruptedException {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("deviceName", "Galaxy C9 Pro");
capabilities.setCapability("platformVersion", "8.0.0");

capabilities.setCapability("appPackage", "com.android.chrome");
capabilities.setCapability("appActivity", "com.google.android.apps.chrome.Main");
capabilities.setCapability("startIWDP", true);
capabilities.setCapability("adbExecTimeout", 20000);
capabilities.setCapability(MobileCapabilityType.NO_RESET, true);
driver = new AndroidDriver<WebElement>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
driver.manage().timeouts().implicitlyWait(80, TimeUnit.SECONDS);
}
@Test
public void chromeTest() throws InterruptedException {
System.out.println("Hello Android");
System.out.println("Started Mobile Testing......");
//driver.manage().timeouts().implicitlyWait(60,TimeUnit.SECONDS);
System.out.println("start");
System.out.println("after wait 3000----------------------------------------------");
Set<String> context = driver.getContextHandles();
System.out.println(context.size());
for(String contexts : context) { System.out.println(contexts); }
WebElement searchbar_txt = driver.findElementById("com.android.chrome:id/search_box_text");
searchbar_txt.click();
WebElement url_Bar = driver.findElementById("com.android.chrome:id/url_bar");
url_Bar.sendKeys("amazon.in");
WebElement urlhistory = driver.findElementByXPath("//*[@text='amazon.in']");
// findElementByName("Kotak Securities");
urlhistory.click();
Thread.sleep(4000);
Set<String> context1 = driver.getContextHandles();
System.out.println(context1.size());
for(String contexts : context1) { System.out.println(contexts); }
// driver.context((String) context1.toArray()[1]);
driver.context("WEBVIEW_chrome");
Thread.sleep(4000);
driver.findElementById("nav-search-keywords").sendKeys("Bags");
driver.findElementByTagName("Submit").click();

无需切换上下文，您可以 运行 它具有 chrome 功能和 chrome 驱动程序本身的路径。
包括行：
