Unable find element at Android 7.0 and Appium 1.5.3

[tomliuxin]

Appium:1.5.3 (using npm install -g appium@1.5.3 to upgrade the appium to 1.5.3 version) Android version: 7.0 emulator node version: 4.6.0

using the below code can initialize the driver:

        DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities.SetCapability("device", "Android");
            capabilities.SetCapability(CapabilityType.Platform, "Windows");
            capabilities.SetCapability("deviceName", deviceName);
            capabilities.SetCapability("platformName", "Android");
            capabilities.SetCapability("platformVersion", "7.0");
            capabilities.SetCapability("automationName", "Appium");
            capabilities.SetCapability("unicodeKeyboard", "True");
            capabilities.SetCapability("resetKeyboard", "True");
            capabilities.SetCapability("appPackage", appPackage);
            capabilities.SetCapability("appActivity", appActivity);

        Uri uri = new Uri(uriString);
        TimeSpan timeSpan = TimeSpan.FromMinutes(20);
        myDriver = new AndroidDriver<AppiumWebElement>(uri, capabilities, timeSpan);

but using the By.className can't find element (any classname can't find element even the classname is correct)

AndroidDriverUtility.FindElementsByClassName("android.widget.ImageView");

does anybody met this issue? how to resolve it? Thanks.

Have you tried Appium 1.6.0?

[rafalf]

think I have encountered it too. had to use IDs and ACCESSIBILITY ID I am on 1.6.0, Android 5.1.1 and automating a native app.

[tomliuxin]

@mykola-mokhnach, Thanks. Yes, I have tried at Appium 1.6.0 and Appium 1.5.2. all met the same as issue. Issue: can initialize the Android driver, but run cases very slowly, andCANNOT find the element.

and also, I have tried at appium Version: 1.3.7,Version: 1.4.13, Version: 1.4.16 issue:can’t initialize the Android driver.

the issue is not repro at the android version 6.0, only repro at android version 7.0

[tomliuxin]

@rafalf , Thanks your suggestion. but our app, some of UI element are not have Ids or Accessbility Id. did you run cases at android 7.0?

[mykola-mokhnach]

Probably, it's a good time now to start using UIAutomation2 framework.

[imurchie]

Android 7 is not supported in Appium 1.5.3. You can upgrade, and then post the logs for the test run as a gist. Getting the source might be useful, as well.

@mykola-mokhnach, Thanks. could you help to let me know how to use the UIAutomation2 framework.? Thanks.

[tomliuxin]

@imurchie , Thanks. Yes, I have upgrade the appium to 1.6.0 (npm -g install appium@1.6.0), met the same as issue. The driver can initialize, and the API presskeyCode(), Swipe(), worked fine. but when execute the method: FindElement By className, NO found element.

NO element find.

@mykola-mokhnach, I changed the initialize driver code as below: DesiredCapabilities capabilities = new DesiredCapabilities(); capabilities.SetCapability("device", "Android"); capabilities.SetCapability(CapabilityType.Platform, "Windows"); capabilities.SetCapability("deviceName", deviceName); capabilities.SetCapability("platformName", "Android"); capabilities.SetCapability("platformVersion", "7.0"); capabilities.SetCapability("automationName", "uiautomator2"); capabilities.SetCapability("unicodeKeyboard", "True"); capabilities.SetCapability("resetKeyboard", "True"); capabilities.SetCapability("appPackage", appPackage); capabilities.SetCapability("appActivity", appActivity);

(automationName changed to: uiautomator2), not sure is it right or not.

but met one issue: Error while killing uiAutomator: Error: Unable to kill io.appium.uiautomator2.server processes. Original error: Unable to get pids for tomator2.server

Encountered internal error running command: ProxyRequestError: Could not proxy command to remote server. Original error: Error: read ECONNRESET

[sravanmedarapu]

Can you try by updating appium-uiautomator2-driver to 0.0.7 ?

[tomliuxin]

@sravanmedarapu, Thanks. how to update it? Thanks.

[sravanmedarapu]

npm update appium-uiautomator2-driver

[tomliuxin]

@sravanmedarapu, Thanks.

after executed the CMD: still met the issue: [ADB] Error: Unable to kill io.appium.uiautomator2.server processes. Original error: Unable to get pids for tomator2.server. Orginial error: this.shell(...).trim is not a function

[imurchie]

What is the source at the point that you do the searches for elements? The first one works, the second, searching within the first, does not. It would be interesting to see what the source is.

[sravanmedarapu]

it seems update was not successful. Can you uninstall 'npm uninstall appium-uiautomator2-driver' and reinstall with 'npm install appium-uiautomator2-driver@0.0.7'

Adding logs in gist would be more helpful.

[tomliuxin]

@imurchie: Find element code: public static AppiumWebElement WebView { get { return AndroidDriverUtility.FindElementByClassName("android.webkit.WebView"); } }

public static ReadOnlyCollection EditTexts { get { return WebView.FindElementsByClassName("android.widget.EditText"); } }

[sravanmedarapu]

For finding the elements in the webview you need to switch to webview context before finding element, refer this example

and for finding the element properties in webview refer https://developers.google.com/web/tools/chrome-devtools/remote-debugging/

[sravanmedarapu]

Not able to replicate the issue. Can you share adb logs(command adb logcat) in a separate file in gist. Please clear the logs before executing the test(adb logcat -c).

Coming to your findElement issue, Have you tried by switching the context to webview in old driver at least(with out UIAutomator2 in capabilities).

[tomliuxin]

@sravanmedarapu , @imurchie Thanks for your help. The issue has been resolved. maybe I missed something at last times.

now, upgrade the appium to 1.6.0, npm install -g appium --no-shrinkwrap upgrade the uiautomator2 to 0.0.7 npm install appium-uiautomator2-driver@0.0.7

changed the android initialize code as below: capabilities.SetCapability("platformVersion", "7.0"); capabilities.SetCapability("automationName", "uiautomator2");

start the appium: "C:\Users\v-tomliu\AppData\Roaming\npm\appium.cmd" -a 127.0.0.1 -p 4723

and then run cases, successfully.

Thanks.

[tomliuxin]

@sravanmedarapu

it is very strange, it can find element for webView, but it can't find element for Button:

Find element code:

private static AppiumWebElement WebView (can find) { get { return AndroidDriverUtility.FindElementByClassName("android.webkit.WebView"); } }

public static AppiumWebElement Skip (can't find) { get { return WebView.FindElementsByClassName("android.widget.Button")[0]; } }

@tomliuxin - Dont take me wrong. Dude, can you start using gist please. https://gist.github.com/ for logs. I am also interested in this issue. This might be worth reading too markup

[tomliuxin]

@rafalf , thanks.

created one gist: https://gist.github.com/tomliuxin/40841232433d119f3442f749b515ca43

[tomliuxin]

@rafalf , sorry, this is public: https://gist.github.com/tomliuxin/cc9e3b2e2e894de997b30dec918bcd19

[sravanmedarapu]

For finding elements under webview you need to switch to webview context.

        Set<String> contextNames = driver.getContextHandles();
        for (String contextName : contextNames) {
            if (contextName.contains("WEBVIEW")) {
                driver.context(contextName);
            }
        }

Element properties under webview will not contain native attributes(as webviews built on HTML), to get the element properties under webview you can use chrome remote debugging - https://developers.google.com/web/tools/chrome-devtools/remote-debugging/

[tomliuxin]

@sravanmedarapu Thanks.

after I used the code to switch the context.: ReadOnlyCollection contexts = myDriver.Contexts; for (int i = 0; i < contexts.Count; i++) { if (contexts[i].Contains("WEBVIEW")) { myDriver.Context = contexts[i]; break; } } met one issue: [Chromedriver] Error: unknown error: Chrome version must be >= 53.0.2785.0 (Driver info: chromedriver=2.25.426923 (0390b88869384d6eb0d5d09729679f934aab9eed),platform=Windows NT 10.0.14393 x86_64)

and how to upgrade the Chrome browser for emulator, my emulator chrome version is 51.0.2704.90, I want to uninstall it and re-install the latest version, but met one issue. the chrome can't delete due to this is installed when emulator created.

C:\Users\v-tomliu>adb uninstall com.android.chrome Failure [DELETE_FAILED_INTERNAL_ERROR]

[tomliuxin]

and run cases at android 7.1.1 and chrome version is:53.0.2785.134, met the same as issue: [Chromedriver] Error: unknown error: Chrome version must be >= 53.0.2785.0 (Driver info: chromedriver=2.25.426923 (0390b88869384d6eb0d5d09729679f934aab9eed),platform=Windows NT 10.0.14393 x86_64)

[SrinivasanTarget]

Latest version of chromedriver works fine with the latest chrome browser. Please update your chrome browser to 54.x.x and give a try.

[rafalf]

There's a link where chrome apks are: http://testprojects.co/automation/2016/10/20/appium-installation-python-chrome.html

[tomliuxin]

@rafalf , thanks for sharing this.

[tomliuxin]

@SrinivasanTarget why I still met this issue, after I upgrade the Chrome browser to 54.0.2840.85

appium 1.6.0 android emulator 7.0 uiautomator2, version 0.0.7 chrome browser 54.x.x chrome driver 2.25.426923

[tomliuxin]

and the below code initialize the driver DesiredCapabilities capabilities = new DesiredCapabilities(); capabilities.SetCapability("device", "Android"); capabilities.SetCapability(CapabilityType.Platform, "Windows"); capabilities.SetCapability("deviceName", deviceName); capabilities.SetCapability("platformName", "Android"); capabilities.SetCapability("platformVersion", "7.0"); capabilities.SetCapability("automationName", "uiautomator2"); capabilities.SetCapability("unicodeKeyboard", "True"); capabilities.SetCapability("resetKeyboard", "True"); capabilities.SetCapability("appPackage", appPackage); capabilities.SetCapability("appActivity", appActivity); capabilities.SetCapability("newCommandTimeout", "30000");

        Uri uri = new Uri(uriString);
        TimeSpan timeSpan = TimeSpan.FromMinutes(20);
        myDriver = new AndroidDriver<AppiumWebElement>(uri, capabilities, timeSpan);

        ReadOnlyCollection<string> contexts = myDriver.Contexts;

        for (int i = 0; i < contexts.Count; i++)
        {
            if (contexts[i].Contains("WEBVIEW"))
            {
                myDriver.Context = contexts[i];
                break;
            }
        }

[rafalf]

Kill that emulator and start from scratch. Once created install the apk.

[tomliuxin]

@rafalf , could you help to provide more details about this? Thanks.

I created one new emulator 7.0 and there is NO chrome browser at this emulator, then I install the 54.0.2840.85 version chrome to that emulator: adb install ***.apk checked the chrome browser installed successfully.

but I run the cases still met the issue. MJSONWP] Encountered internal error running command: Error: unknown error: Chrome version must be >= 53.0.2785.0

not sure why? Thanks.

Thanks rafalf.

I don't know why, I kill the emulator and created again and again, and try at: chrome browser: 54.0.2840.85 and 54.0.2840.68, still met that issue........

[tomliuxin]

using the below switch the context:
myDriver.Context = contexts[i]; met the issue: Error: unknown error: Chrome version must be >= 53.0.2785.0

using the below code switch the context: myDriver.SwitchTo().Window(contexts[i]); met the issue: Encountered internal error running command: Error: Could not proxy. Proxy error: Could not proxy command to remote server. Original error: 404 - undefined

@tomliuxin -- Ok you must have the appium 1.6.1 beta it's all working well for me with -- com.android.chrome_54.0.2840.68-284006811_minAPI21(x86)(nodpi)_apkmirror.com.apk and beta

@rafalf

which version for appium-uiautomator-driver at your machine? 0.0.7? did you use the C# code?

[tomliuxin]

when execute the below code to get the driver width, met the issue:

Driver.Manage().Window.Size.Width

Error: unknown error: operation is unsupported on Android\n (Session info: chrome=51.0.2704.91)

[rafalf]

Python. Idont know much about webdriver C# but i think you might be doing it wrong maybe Maybe New Size() ? http://yizeng.me/2014/02/23/how-to-get-window-size-resize-or-maximize-window-using-selenium-webdriver/#c-sharp-example
