使用Appium在Android chrome中切换窗口不起作用

Question

我正在尝试将可正常运行的Selenium Web自动化测试转换为android自动化测试。但是，我在切换到新窗口时遇到问题。单击自动链接后有两个打开的窗口，但是在执行driver.switchTo（）。window（currentHandle）之后，即使窗口句柄正在切换，我仍然会获得第一个窗口的URL。我的切换方法正确吗？

private WebDriver androidTest() {

    //Set the Desired Capabilities
    DesiredCapabilities caps = new DesiredCapabilities();
    caps.setCapability("deviceName", "My Phone");
    caps.setCapability("udid", "521094ceea16c35f");
    caps.setCapability("platformName", "Android");
    caps.setCapability("platformVersion", "6.0.1");
    caps.setCapability("browserName", "Chrome");
    caps.setCapability("appPackage", "com.android.chrome");
    caps.setCapability("noReset", true);

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

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

    logger.debug("==== WebDriver Capabilities ====", new Object[0]);
    logger.debug("Browser Name = {0}", new Object[] { caps.getBrowserName() });
    logger.debug("Version = {0}", new Object[] { caps.getVersion() });

    return driver;
}


    public String switchToNewWindow(WebDriver driver){
            String currentHandle=null;
            System.out.println("windowH"+  driver.getWindowHandles());
            for (String handle : driver.getWindowHandles()) {
                  System.out.println("url :" + driver.getCurrentUrl() + handle);
                  If(!handles.contains(handle)){
                         currentHandle = handle;
                         handles.push(currentHandle);
                         driver.switchTo().window(currentHandle);
                         System.out.println("url :" + driver.getCurrentUrl() + handle);
                         break;
                }                                             
          }

   return currentHandle;

}
