Steps to reproduce the problem:
1. Create an Android app using a WebView
2. Register a WebViewClient with the WebView that logs on onPageStarted, onPageFinished and onReceivedHttpAuthRequest
3. Load a page that uses NTLM authentication in the WebView

Example Code:
package com.example.webviewtest;

import android.graphics.Bitmap;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.HttpAuthHandler;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        WebView myWebView = new WebView(this.getApplicationContext());
        setContentView(myWebView);

        myWebView.setWebViewClient(new MyWebViewClient());
        myWebView.loadUrl("http://IP/app");

    }

    class MyWebViewClient extends WebViewClient {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            android.util.Log.d("MyWebViewClient", "Page Started");
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            android.util.Log.d("MyWebViewClient", "Page Finished");
        }

        @Override
        public void onReceivedHttpAuthRequest(WebView view, HttpAuthHandler handler, String host, String realm) {
            super.onReceivedHttpAuthRequest(view, handler, host, realm);
            android.util.Log.d("MyWebViewClient", "Auth Request: " + host + " " + realm);
        }
    }
}

What is the expected behavior?
The order of events should be PageStarted, ReceivedHttpAuthRequest, PageFinished.

What went wrong?
If the URL has a domain name the order of events is PageStarted, ReceivedHttpAuthRequest, PageFinished. If the URL has an IP address or machine name as the host the order of events is ReceivedHttpAuthRequest, PageStarted, PageFinished.

If the Android System WebView or Chrome app is reverted to 68 it works consistently.

Did this work before? Yes 68

Does this work in other browsers? N/A
