无法检测 webview Appium

Question

I am trying to automate an hybrid phonegap application through Appium. While this app is running on a phone I can access it remotely through the Chrome browser. When I use Appium it doesn't show the webview context and only displays the native context. Is there a way to access the webview context and what am I doing wrong?

        var dirs = Directory.GetFiles("out", "*.apk");
        var app = Path.GetFullPath(dirs[0]);
        DesiredCapabilities cap = new DesiredCapabilities();
        cap.SetCapability("fastReset", "True");
        cap.SetCapability("platformName", "Android");
        cap.SetCapability("automationName", "Appium");
        cap.SetCapability("app", app);
        cap.SetCapability("deviceName", "emulator-5554");
        cap.SetCapability("autoGrantPermissions", "true");
        AppiumDriver<AppiumWebElement> driver1 = new AndroidDriver<AppiumWebElement>(new Uri("http://192.168.1.138:4723/wd/hub"),cap);
        Thread.Sleep(15000);
        var contexts = driver1.Contexts;
        foreach(string context in contexts)
        {
            if (context.Contains("WEBVIEW"))
            {
                driver1.Context = context;
                break;
            }
        }
        driver = driver1

Adding a log file as well:

Found the reason why it wasn't detecting the webview. The app is build with phonegap and uses crosswalk. This causes the issue that Appium (under normal conditions) can't find a webview.

Answer 1

Try printing all the available context.sometimes the spellings or case might be different.following is the psuedo code.

foreach(string context in contexts)
{
    print(context)
}

Also check whthwr you have webview debugging enabked in code.

To do it use

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    WebView.setWebContentsDebuggingEnabled(true);
}
