WebView not loading certain pages

Question

Unable to load following webpage in WebView

Tried following so far -

    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setLoadWithOverviewMode(true);
    webView.getSettings().setUseWideViewPort(true);
    webView.getSettings().setPluginState(WebSettings.PluginState.ON);
    webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    webView.getSettings().setAllowFileAccess(true);
    webView.getSettings().setDomStorageEnabled(true);
    webView.getSettings().setUserAgentString("Android WebView");
    webView.setWebViewClient(new WebViewClient() {

      @Override
      public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
        view.loadUrl(request.getUrl().getPath());
        //if (progressDialog != null && progressDialog.isShowing()) {
        //  progressDialog.dismiss();
        //}
        return true;
      }

      //If you will not use this method url links are opeen in new brower not in webview
      @Override
      public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
      }

      //Show loader on url load
      @Override
      public void onLoadResource(WebView view, String url) {
      }
      @Override
      public void onPageFinished(WebView view, String url) {
        try {
          //if (progressDialog.isShowing()) {
          //  progressDialog.dismiss();
          //}
        } catch (Exception exception) {
          exception.printStackTrace();
        }
      }

      @Override
      public void onReceivedError(
        WebView view, WebResourceRequest request, WebResourceError error
      ) {
        //progressDialog.dismiss();
        super.onReceivedError(view, request, error);
      }

    });

I have already provided internet permission. The URL loads fine everywhere, except on WebView. I get following error -

Get following Info on my console -

I think you have to refer to [this](https://stackoverflow.com/q/31764414/1083957) question. — azizbekian, Nov 21 '17 at 07:47
@azizbekian You mean to say that backend has to do this? But the url is loading on mobile browsers properly, just not loading on WebView. — Rohan Kandwal, Nov 21 '17 at 10:37
@RohanKandwal if your internet permission is `INTERNET` https://stackoverflow.com/a/31533625/1032167 and you see the log message you provided can you show what you see on the screen? some error message? — varren, Nov 21 '17 at 19:39
@varren Permission is correct since I am able to load another websites when I change URL. I am not able to load only this particular URL. There are no errors except what I pasted in question. All I see is a blank white screen. — Rohan Kandwal, Nov 22 '17 at 05:33

Use below code and it should work, I tested and it worked.

public class WebViewEx extends AppCompatActivity {

    private WebView webView;
    private ProgressDialog progDailog;
    Activity activity;


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

        webView = findViewById(R.id.webView);
        activity = this;

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


        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setLoadWithOverviewMode(true);
        webView.getSettings().setUseWideViewPort(true);
        webView.getSettings().setDomStorageEnabled(true);
        webView.setWebChromeClient(new WebChromeClient());
        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("https://6awlanow.com/about/faqs");
    }
}

Your XML will be like below:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <WebView
        android:id="@+id/webView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>

Below is the result I got in WebView:

I hope this will resolve your issue and let me know if you have any query.

That's strange, the url loaded for you is correct, however it is still not loading for me. Other URLs loading fine for me except this one still. I will create a project on GitHub with the relevant code in few hours. Please have a look at it then. — Rohan Kandwal, Nov 22 '17 at 10:21
@RohanKandwal sure and then share the link with me, I will have a look and find out what's the issue. — Pankaj Mundra, Nov 22 '17 at 10:27
@RohanKandwal your code is working fine on my device. The webview is opening the URL. Did you try to run your application on any other device? — Pankaj Mundra, Nov 24 '17 at 04:04
@PankajMudra That's strange... It is working fine on some emulators but not on others, but since it is working fine on mobiles, it works for now. — Rohan Kandwal, Nov 25 '17 at 13:03

what worked for me is

1 .Enabling dom Storage and javascript

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

2.running webview on handler

 new Handler().post(new Runnable() {
                   @Override
                   public void run() {

                       webView.loadUrl(webview_url);

                   }
               });
