Unable to find an element in Browser of the Android emulator using Appium and C#

问题

I want to automate mobile web site testing on Android emulator using c# and Appium. There is a simple test scenario I want to automate for the start:
1. Start Browser
2. Find an element
3. Clear it
4. Send keys

I've got a problem with the second step. Every time MSTest tries to execute FindElementById line in the code below, I get the error: "An element could not be located on the page using the given search parameters."

[TestClass]
public class UnitTest1
{
    private DesiredCapabilities _capabilities;
    private AndroidDriver _driver;

    public void InitializeDriver()
    {
        Console.WriteLine("Connecting to Appium server");
        _capabilities = new DesiredCapabilities();

        _capabilities.SetCapability("deviceName", "test_02");
        _capabilities.SetCapability(CapabilityType.BrowserName, "Chrome");
        _capabilities.SetCapability(CapabilityType.Version, "5.0.1");
        _capabilities.SetCapability(CapabilityType.Platform, "Android");

        //Application path and configurations
        _driver = new AndroidDriver(new Uri("http://127.0.0.1:4723/wd/hub"), _capabilities);
    }

    [TestMethod]
    public void TestMethod1()
    {
        InitializeDriver();

        var element = _driver.FindElementById("com.android.browser:id/url");
        element.Clear();
        element.SendKeys(@"http://stackoverflow.com/");
    }
}

Input string for the method I've got from UIAutomator that is shown below.

I tried several combinations for the FindElementById input method:
"com.android.browser:id/url"
"id/url"
"url"
but no luck.

My environment:
Windows 8.1
Appium 1.3.4.1
ChromeDriver 2.14.313457
Android Device Monitor 24.0.2

Sorry for misleading !!! In case of testing web apps in browser the elements should be located as usual elements on the web page ( not as some classes like android.widget.EditText and android.widget.Button). So try for example the following and you will see some result:

    var element = _driver
            .findElementByXPath("//input[@id='lst-ib']");

To get locators you should run the browser on your desktop, open the page and use some tools/extensions like Firebug in Firefox or Firebug Lite in Chrome browser.

Try these 2 statements:

var element = _driver.FindElement(By.Id("com.android.browser:id/url");
driver.findElementsByXPath("//*[@class='com.android.browser' and @index='1']");

Update ! The following approach is not for web testing:

Could you try to find the element using xpath?

@FindBy(xpath="//android.widget.EditText[contains(@resource-id, 'url')]")

So in your case you can try the following:

var element = _driver.findElementByXPath("//android.widget.EditText[contains(@resource-id, 'url')]");

Update: in case of testing web apps (not native) you should use web page locators instead of Android classes.
