Open popup in my WebView

Open popup in my WebView

from the Windows browser when I enter a web page where after registering a new pop-up window is shown, this pop-up window is shown without problems, but when I try to do the same in Android from a WebView that pop-up window does not appear, after entering the username and password is still showing the same page.

Use custom WebView extension to get new tab component.
