Its already mention in your question you have already set the WebViewClient just override one more method which is shouldOverrideUrlLoading() . And you are good to go . — SpiritCrusher

Try this as per your code

 public class NewsActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_news); String url = "https://www.example.com"; WebView web = (WebView) findViewById(R.id.webView4); web.loadUrl(url); final WebView mWebView = (WebView) findViewById(R.id.webView4); mWebView.getSettings().setJavaScriptEnabled(true); mWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY); mWebView.getSettings().setSavePassword(true); mWebView.getSettings().setSupportZoom(true); mWebView.getSettings().setSaveFormData(true); mWebView.getSettings().setSupportZoom(false); mWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE); mWebView.getSettings().setDomStorageEnabled(true); mWebView.getSettings().setSupportMultipleWindows(false); mWebView.getSettings().setLightTouchEnabled(true); mWebView.getSettings().setBuiltInZoomControls(true); mWebView.getSettings().setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NORMAL); webview.setWebViewClient(new WebViewClient() { public boolean shouldOverrideUrlLoading (WebView view, String url){ return true; } }); mWebView.loadUrl("https://www.example.com"); } }

Yes you can use JavaScriptInterface in Java file and call this function in your particular webpage
What would be the code ? Can you show me please I'm new to this

Try this code this will also handle shouldOverrideUrlLoading deprecation in Nougat and above

mWebview.setWebViewClient(new WebViewClent() { @SuppressWarnings("deprecation") @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { if (Uri.parse(url).getHost().equals("http://www.example.com")) { // This is my web site, so do not override; let my WebView load the page return false; } // reject anything other by returning true return true; } @RequiresApi(Build.VERSION_CODES.N) @Override public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) { String url=request.getUrl().toString(); if (Uri.parse(url).getHost().equals("http://www.example.com")) { // This is my web site, so do not override; let my WebView load the page return false; } // reject anything other return true; } }

 webview.setWebViewClient(new WebViewClient() { public boolean shouldOverrideUrlLoading (WebView view, String url){ //True if the host application wants to leave the current WebView and // handle the url itself, otherwise return false. return true; } });

Use Like this :

 WebView webview = new WebView(context); webview.setWebViewClient(new WebViewClient() { @Override public void onPageStarted(WebView view, String url, Bitmap favicon) { super.onPageStarted(view, url, favicon); Log.d("WebView", "your current url when webpage loading.." + url); } @Override public void onPageFinished(WebView view, String url) { Log.d("WebView", "your current url when webpage loading.. finish" + url); super.onPageFinished(view, url); } @Override public void onLoadResource(WebView view, String url) { // TODO Auto-generated method stub super.onLoadResource(view, url); } @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { System.out.println("when you click on any interlink on webview that time you got url :-" + url); return super.shouldOverrideUrlLoading(view, url); } });

Where should I add this line of code? Or is it possible if you can show me where you added it thanks
