Can I please have some support here!!!

If you drop the “OR” and query the elements individually, does it continues to break?

P.S. - Try and drop the xpath and use other locators.

8

What I have been doing in Python Appium for the last two years is stick to find_element_by_android_uiautomator when I have to use Xpath ordinarily. This has been pretty stable to me. Good luck.

9

I also I see you are using 1000 in WebDriverWait. This is way too short.

10

Webdriverwait is based in seconds, not milliseconds, so 1000 is substantial actually. @Telmo_Cardoso, it breaks regardless of OR, unfortunately…even if I just look for a single element. I am beginning to think it is all the animations on screen that are causing it to crash.

I will give ‘android_uiautomator’ a try…assuming this will work with uiautomator2, correct?

11

@mayu Can you give me an actual example of a ‘find_element_by_android_uiautomator’ with a wait? thanks

12

You can turn off animation from settings (I always have it turned off. )

13

disableWindowAnimation = true is what I am using…but does not disable all of them, oddly enough…

14

As for example, I see: el = self.driver.find_element_by_android_uiautomator(‘new UiSelector().description(“Animation”)’)…but how can that be used in my case where I need Xpath as shown in my example in my original post??

15

Use https://developer.android.com/reference/android/support/test/uiautomator/UiSelector#text

16

Ok I got the following to work: element = self.driver2.find_element_by_android_uiautomator(‘new UiSelector().text(“From this device”)’)…but how can I add a wait until text is found condition? or wait until text is gone?

17

You can use a FluentWait

FluentWait fluentWait = new FluentWait<>(driver).withTimeout(Duration.ofSeconds(waitTime)).pollingEvery(Duration.ofSeconds(1)).ignoring(NoSuchElementException.class)
return (MobileElement) fluentWait.until(webDriver -> ((AndroidDriver) driver).findElementByAndroidUIAutomator(query));
18

Fluentwait is throwing syntax error…

19

Is fluentWait really available in Python biding? Unfortunately, in Python, I have been noticing that we do not have all the nice things that APPIUM Java binding offers. (I am sticking to Python because I like the language. )

Use EC right before your find_element_by_android_uiautomator call if you need to.

20

I just tried:

wait = WebDriverWait(self.driver2, 3000, poll_frequency=1, ignored_exceptions=[ElementNotVisibleException, ElementNotSelectableException])
element = wait.until(EC.invisibility_of_element_located((By.ID, “com.app.example:id/overAllProgressStop”)))

acting as a ‘fluent wait’, but we will see. Next I will try EC call before find by uiautomator.

Thanks guys
