Android Webview: Disable confirm navigation

Question

Is it possible to disable a confirm navigation pop up in android webview from a website that I am viewing?

I tried this one and I what I did is just return 'true' without showing any pop-up, but the navigation pop up still shows up. I want to disable it and I would like to just automatically navigate without any warning.

Here's the CustomWebChromeClient for my webview

public class CustomWebChromeClient extends WebChromeClient {

    @Override
    public boolean onJsConfirm(WebView view, String url, String message, JsResult result) {
        return true;
    }
}

You can override onJsBeforeUnload to always return true.

onJsBeforeUnload is the callback that gets invoked before the confirm navigation dialog pops up.

https://developer.android.com/reference/android/webkit/WebChromeClient.html#onJsBeforeUnload(android.webkit.WebView, java.lang.String, java.lang.String, android.webkit.JsResult)

Edit: As mentioned by AndyW, confirm or cancel methods should be invoked on jsResult argument otherwise the app might freeze because of the pending javascript dialog.

Worth noting that returning true will prevent the dialog, but you will still need to call a method from the JsResult object. E.g jsResult.cancel() – AndyW Jul 03 '18 at 08:57
As pointed by AndyW . Always call JsResult.cancel() or JsResult.confirm() before returing true , or else the WebView will not work and show abnormal behaviour – Mohit Singh Mar 20 '20 at 14:37

For me overriding onJsBeforeUnload as followed did it:

@Override
public boolean onJsBeforeUnload(WebView view, String url, String message, JsResult result) {
     result.confirm();
     return true;
}

Why don't you create a webView in xml and use that webview in activity instead of using a class with webChromeClient, the below steps may help you.

step 1: Create a webview in your xml file and call this view in Java

webView = (WebView) findViewById(R.id.exampleWebView);

step 2:

    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setDomStorageEnabled(true);

step 3:

webView.loadUrl(getResources().getString(R.string.olo_non_loggedin_url));
webView.setWebViewClient(new WebViewClient() {

        @Override
        public void onPageStarted(WebView view, String url,
                Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            pBar.setVisibility(View.VISIBLE);
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            pBar.setVisibility(View.GONE);
        }
    });
