Answer 1

In my Case, Adding the below functions to WebViewClient fixed the error. the functions are:onReceivedSslError and Depricated and new api versions of shouldOverrideUrlLoading

        webView.setWebViewClient(new WebViewClient() {

        @SuppressWarnings("deprecation")
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            Log.i(TAG, "loading: deprecation");
            return  true;
            //return super.shouldOverrideUrlLoading(view, url);
        }

        @Override
        @TargetApi(Build.VERSION_CODES.N)
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            view.loadUrl(request.getUrl().toString());
            Log.i(TAG, "loading: build.VERSION_CODES.N");
            return true;
            //return super.shouldOverrideUrlLoading(view, request);
        }

        @Override
        public void onPageStarted(
                WebView view, String url, Bitmap favicon) {
            Log.i(TAG, "page started:"+url);
            super.onPageStarted(view, url, favicon);
        }

        @Override
        public void onPageFinished(WebView view, final String url) {

            Log.i(TAG, "page finished:"+url);

        }

        @Override
        public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError er) {
            handler.proceed();
        }

    });

Did you added the internet permission in your manifest file ? if not add the following line.

 <uses-permission android:name="android.permission.INTERNET"/> 

hope this will help you.

EDIT

Use the below lines.

    public class WebViewDemo extends Activity {


        private WebView webView;


        Activity activity ;
        private ProgressDialog progDailog; 

        @SuppressLint("NewApi")
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

            activity = this;

            progDailog = ProgressDialog.show(activity, "Loading","Please wait...", true);
            progDailog.setCancelable(false);



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



           webView.getSettings().setJavaScriptEnabled(true);     
           webView.getSettings().setLoadWithOverviewMode(true);
           webView.getSettings().setUseWideViewPort(true);        
            webView.setWebViewClient(new WebViewClient(){

                @Override
                public boolean shouldOverrideUrlLoading(WebView view, String url) {
                    progDailog.show();
                    view.loadUrl(url);

                    return true;                
                }
                @Override
                public void onPageFinished(WebView view, final String url) {
                    progDailog.dismiss();
                }
            });

            webView.loadUrl("http://www.teluguoneradio.com/rssHostDescr.php?hostId=147");

           }
    }

Answer 3

Use the following things on your webview

webview.setWebChromeClient(new WebChromeClient());

then implement the required methods for WebChromeClient class.

Answer 4

Use this it should help.

 var currentUrl = "google.com" 
 var partOfUrl = currentUrl.substring(0, currentUrl.length-2)

 webView.setWebViewClient(object: WebViewClient() {

 override fun onLoadResource(WebView view, String url) {
 //call loadUrl() method  here 
 // also check if url contains partOfUrl, if not load it differently.
 if(url.contains(partOfUrl, true)) {
     //it should work if you reach inside this if scope.
 } else if(!(currentUrl.startWith("w", true))) {
     webView.loadurl("www.$currentUrl")

 } else if(!(currentUrl.startWith("h", true))) {
     webView.loadurl("https://$currentUrl")

 } else { 
   //...
 }
 }

 override fun onReceivedSslError(view: WebView?, handler: SslErrorHandler?, error: SslError?) {
  // you can call again loadUrl from here too if there is any error.
}
 // You should also override other override method for error such as
 // onReceiveError to see how all these methods are called one after another and how
// they behave while debugging with break point. 
}
