[Android] element.findElements() returns wrong result

Hi,

I’m using Appium@1.3.4 and Android 4.4.4.

Our app has a page that contains a list of TV channels. Each channel MAY have a little LIVE icon. This is how it looks on the UI :

And this is the UI hierarchy for the channel w/o LIVE icon :

and with LIVE icon :

At first I’m finding the channel element using :

WebElement firstChannel = driver.findElements(By.id("com.company.app:id/visibleChannel")).get(0);

Then I’m looking for child LIVE element under the channel. And the problem is that if the channel element does not contain LIVE icon, appium anyway returns some element. I found out that it is the nearest available LIVE icon from the nearest channel in the UI tree. So for that case the following code returns 1 :

firstChannel.findElements(By.id("com.company.app:id/listing_live_btn")).size();

And here’s corresponding appium log :

Interesting thing is that if I will use Xpath then corresponding code will return 0 as expected :

driver.findElementsByXPath("//*[@resource-id='com.company.app:id/visibleChannel'][1]//*[@resource-id='com.company.app:id/listing_live_btn']").size()

Also log for that case :

Ok, here’s how it could be done:

• on the Google Play Market find and install Horizon Go app: https://play.google.com/store/apps/details?id=com.lgi.orionandroid
• select any country (e.g. Ireland), skip Sign in page and go to TV Guide page
• tap Search icon on the top-right corner and type any short search keyword (like th)
• you will see a list of TV programs (search items) and some of them will have LIVE icon
• try to find an item without LIVE icon, and then try to search for LIVE icon inside it:

WebElement e = driver.findElements(By.id("com.lgi.orionandroid:id/stickyItem")).get(0);
e.findElements(By.id("com.lgi.orionandroid:id/listing_live_btn")).size();
/* (int) 1 */

• if you will execute findElements() and use XPath you will see other result - as expected:

driver.findElements(By.xpath("//*[@resource-id='com.lgi.orionandroid:id/stickyItem'][1]//*[@resource-id='com.company.app:id/listing_live_btn']")).size();
/* (int) 0 */

• screen layout for that case may look smth like this :
