isDisplayed() error, Method is not implemented. Conditional try catch implementation is not working

[OnurSerbes]

The problem

I am trying to check if the element is present or not, so I am using "isDisplayed()" but it gives me "Exception in thread "main" org.openqa.selenium.UnsupportedCommandException: Method is not implemented" error. I checked the other issues most of them are about the client version. I updated all my clients but still gives me the error.

Environment

• Appium version (or git revision) that exhibits the issue: 1.22.3
• Desktop OS/version used to run Appium: Windows 10
• Node.js version (unless using Appium.app|exe): 16.14.0
• Npm or Yarn package manager: npm 8.16.0
• Mobile platform/version under test: Android 12
• Real device or emulator/simulator: Real device
• Appium CLI or Appium.app|exe: from directly cmd

Details

I also tried with conditions but instead of catches and continues to run, it is just throwing me the error

isElementPresented(By.xpath("blabla"));

 public static boolean isElementPresented(By by){
        try{
            driver.findElement(by);
            System.out.println("store found");
            return true;
        }catch (NoSuchElementException e ){
            System.out.println("store not found");
            return false;
        }
    }

"store found" shows but false condition is not working"

Code To Reproduce Issue [ Good To Have ]

if(driver.findElement(By.xpath("blabla")).isDisplayed()){
            WebElement store = driver.findElement(By.xpath("blabla"));
            String storeText = store.getText();
            System.out.println("store: " + storeText);
        }

This is not a server issue, but rather the client one. It sends some random script to the endpoint instead of calling it properly. Are you sure you use the proper client?

[OnurSerbes]

I was using those two from the beginning. Normaly it's working without any problem. My automation is working, but when I tried to use isDisplayed() it gives me the error.

From which class do you inherit the driver instance?

[OnurSerbes]

This is the java file that I used. You can see the all implementation from here https://gist.github.com/OnurSerbes/b870f0b14ea2b010413aae5e8d08c0e8

[mykola-mokhnach]

    driver = new RemoteWebDriver(url, cap);

RemoteWebDriver is targeting web browsers. Consider using mobile-specific driver classes imported from java-client instead.

[OnurSerbes]

I changed it with AndroidDriver (you can check the gist again), and uncommented this block

        if (driver.findElement(By.xpath("blabla")).isDisplayed()) {
            WebElement store = driver.findElement(By.xpath("blabla"));
            String storeText = store.getText();
            System.out.println("store: " + storeText);
        } else {
            String storeText = "individual";
            System.out.println("store: " + storeText);
        }

but still gives me the same error when a page with no element comes in

Try https://github.com/appium/appium-uiautomator2-driver#elements-cannot-be-found

Maybe the element does not really exist. Did you check the actual page source?

[OnurSerbes]

In some pages it exists I can take the text but some of them don't have it, that is the reason why I am using isDisplayed() am I using wrong ? As I stated, I also tried to avoid it without using isDisplayed() (with isElementPresent function but it's not working either) because of the prevent error.

[mykola-mokhnach]

Probably you have issues understanding the concept of existence/visibility of elements. Try asking at Appium forum about it. You could start at https://discuss.appium.io/t/help-needed-expectedconditions-invisibilityof
