NullPointerException in `void android.view.ViewGroup.getLocationOnScreen(int[])`

[okonor]

There are a few crashes for the users. I'm sure that the exact android version doesn't matter here, but just for case, Android 9 and Android 10. Please, advise what I can do here? Are you planning to support this library? Thank you in advance.

Can you be more specific or share some code in which case you get the exception?
