Closing dialog inside shouldOverrideUrlLoading() or ignoring in project, when is custom url open

Question

I am trying to auth google user in WebView, I found a good solution for these days, it works fine for google login, but I cannot disable dialog in other urls like (, sms: , smsto:)

Example Situation: User click on telephone number in my app, it will open the phone dial, but when he returns back.. there is a empty dialog window with close button, i use it for google login with JS.

How can i close this dialog message inside the shouldOverrideUrlLoading()? Or is there any better solution to not open other links in the dialog? How can i improve my code to solve my problem? Thank you guys!
