Webview setHttpAuthUsernamePassword


I have set http auth (User and Password ) to protect my api.
I used basic auth, work’s but redirect to url don’t, showed blank page…

My blocks:

blocks (3)

I received 200 status code and get response content, but url don’t loading.

I look for:
webview.setHttpAuthUsernamePassword(host, realm, username, password);

It’s possible?
