How to know an mobile application load success?

I’ve an mobile application (android) about digital magazine, it’s also include image, video. When you click on video or image tab, how do you know when it load success? Both visible display and hide elements below visible elements
Is it good if I use this to check:
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(“your locator”)));

Thanks :slight_smile:
