How to intercept and extract content of this popup window.

Answer 1

There is no means for you to "intercept and extract content of this popup window", as one app cannot "intercept and extract content" from the UI of any other app written by somebody else.

One exception would be if your app is running with superuser privileges on a rooted device, where you could take a screenshot and attempt to use OCR or something to "extract content of this popup window".
