Please use for this issue shouldInterceptRequest

@Override
public WebResourceResponse shouldInterceptRequest (final WebView view, String url) {

return super.shouldInterceptRequest(view, url);

}

It can be used for check all url change in webview

Don't know why you add @Deprecated annotation but as I know the old shouldOverrideUrlLoading method indeed deprecated in API level 24.

So if your minSdkVersion is 24 or above you can only use public boolean shouldOverrideUrlLoading(WebView, WebResourceRequest), but using shouldOverrideUrlLoading() (like your code did) can just grab the previous URL if URL changed. if you want to grab the current URL after URL changed you can use @JavascriptInterface

First you should create a custom WebViewClient 

public class MyWebViewClient extends WebViewClient {

    // inject javascript method 'onUrlChange'
    @Override
    public void onPageFinished(WebView view, String url) {
        view.loadUrl("javascript:window.android.onUrlChange(window.location.href);");
    };

    // if your minSdkVersion is 24 you can only use this
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)
    {
        String url = view.getUrl();
       // Log.d("LOG","previous_url: " + url);
        return false;
    }

    static class MyJavaScriptInterface {
        @JavascriptInterface
        public void onUrlChange(String url) {
           // Log.d("LOG", "current_url: " + url);
        }
    }

}

I put both methods into it in case you want, and you can uncomment the Log.d(...) line to check the URL

In your MainActivity.java

...
WebView mWebView = (WebView) findViewById(R.id.YOUR_VIEW_ID);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new MyWebViewClient());
mWebView.addJavascriptInterface(new MyWebViewClient.MyJavaScriptInterface(),
        "android");
mWebView.loadUrl(YOUR_TARGET_URL);
...

Don't forget putting <uses-permission android:name="android.permission.INTERNET" /> into AndroidManifest.xml
