You have to create a custom webchromeclient and handle the popup from webview. Whenever there will requirement of popup from website, you have to load it in alert dialog.

public class WebViewActivity extends AppCompatActivity {

private WebView webViewPopUp;
private AlertDialog builder;
private Context globalContext;

private String url = "https://www.bellyfulstore.com/";

private WebView webView;
private String userAgent;

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

    webView = findViewById(R.id.webView);
    webView.setWebViewClient(new WebViewClient());
    webView.loadUrl(url);

    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);

    // Set User Agent
    userAgent = System.getProperty("http.agent");
    webSettings.setUserAgentString(userAgent + "yourAppName");

    // Enable Cookies
    CookieManager.getInstance().setAcceptCookie(true);
    if(android.os.Build.VERSION.SDK_INT >= 21)
        CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);

    // Handle Popups
    webView.setWebChromeClient(new CustomChromeClient());
    webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
    webSettings.setSupportMultipleWindows(true);
    globalContext = this.getApplicationContext();

    // WebView Tweaks
    webSettings.setRenderPriority(WebSettings.RenderPriority.HIGH);
    webSettings.setCacheMode(WebSettings.LOAD_DEFAULT);
    webSettings.setAppCacheEnabled(true);
    webSettings.setDomStorageEnabled(true);
    webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
    webSettings.setUseWideViewPort(true);
    webSettings.setSaveFormData(true);
    webSettings.setEnableSmoothTransition(true);
    webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);



    webView.setWebViewClient(new WebViewClient() {

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            findViewById(R.id.progressBar).setVisibility(View.VISIBLE);

        }

        public void onPageFinished(WebView view, String url) {
            // do your stuff here
            findViewById(R.id.progressBar).setVisibility(View.GONE);
        }
    });
}




class CustomChromeClient extends WebChromeClient {

Google does not allow default implementations of WebView to be used. Therefore you need to set a custom User-Agent to your WebView:

webView.getSettings().setUserAgentString("YourAppName");

You can use any string instead of YourAppName.

@VladyslavMatviienko Its not working, is there any way to catch the error? – vikas Oct 14 '19 at 13:40
@HarpreetSingh And how does that make it "not work"? – Vladyslav Matviienko Mar 25 '20 at 10:55
didn't say "not work", but it raises alarm to user, just my thought@VladyslavMatviienko – Harpreet Singh Mar 26 '20 at 06:45

Late answer but may help somebody in future.

Actually Google Blocks OAuth Requests Made Via Embedded Browsers. so you can write something like in your code:

 public static final String USER_AGENT = "Mozilla/5.0 (Linux; Android 4.1.1; Galaxy Nexus Build/JRO03C) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.166 Mobile Safari/535.19";
 mWebView.getSettings().setUserAgentString(USER_AGENT);

or you can do like this:

mWebView.getSettings().setUserAgentString("yourAppName");

and you should be able to use sign in with google.

While this code snippet may be the solution, including an explanation really helps to improve the quality of your post. Remember that you are answering the question for readers in the future, and those people might not know the reasons for your code suggestion. – Shawn Hemelstrand Jan 25 '23 at 09:30

If you use firebase for your application. I think you can find a workaround here: https://firebase.google.com/docs/auth/android/google-signin
