Android WebView does not load URL?

Question

I have an Android WebView which should load the following URLs:

https://buchung.salonmeister.de/ort/301655/menue/#offerId=907601&venueId=301655

https://buchung.salonmeister.de/place/#offer-details-page?id=907599&venueId=301655

Here is what I did:

<RelativeLayout 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:background="@android:color/holo_orange_light"
                tools:context=".MainActivityFragment">



    <WebView
        android:id="@+id/webView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true"
        android:layout_margin="5dp"
        android:layout_above="@+id/progressBar"></WebView>


    <ProgressBar
        android:id="@id/progressBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:visibility="invisible"
        style="?android:attr/progressBarStyleHorizontal"/>

    <TextView
        android:id="@+id/titleView"
        android:text="@string/hello_world"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

</RelativeLayout>

In onCreateView():

  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
                           Bundle savedInstanceState) {
       View v = inflater.inflate(R.layout.fragment_main, container, false);

        String url = // some url
        final ProgressBar progressBar = (ProgressBar)v.findViewById(R.id.progressBar);
        progressBar.setMax(100);

        final TextView titleView = (TextView)v.findViewById(R.id.titleView);


        mWebView = (WebView)v.findViewById(R.id.webView);
        mWebView.getSettings().setJavaScriptEnabled(true);
        mWebView.getSettings().setAllowFileAccess(true);
        mWebView.getSettings().setAllowContentAccess(true);

        mWebView.setWebViewClient(new WebViewClient() {
          @Override
          public boolean shouldOverrideUrlLoading(WebView view, String url) {
            return false;
          }
        });

        mWebView.setWebChromeClient(new WebChromeClient() {
          @Override
          public void onProgressChanged(WebView view, int progress) {
            if (progress == 100) {
              progressBar.setVisibility(View.INVISIBLE);
              progressBar.setProgress(0);
            } else {
              progressBar.setVisibility(View.VISIBLE);
              progressBar.setProgress(progress);
            }
          }

          @Override
          public void onReceivedTitle(WebView view, String title) {
            titleView.setText(title);
          }
        });
        mWebView.loadUrl(url);

        return v;
}

The screen is empty when I start my activity.

Note: This is not a layout issue. Please do not comment on layout and focus on the real problem.

How can I load the above urls in a WebView?

Edit: Here are the permissions I gave:

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Edit:

In my console I get the following:

I/chromium: [INFO:CONSOLE(84)] "undefined", source: https://buchung.salonmeister.de/place/ (84)

09-13 15:12:33.230 28407-28407/de.test.webviewtest I/chromium: [INFO:CONSOLE(1)] "Uncaught Error: Script error for: widget/venue-menu/mobile/venue-menu-app

Answer 1

if you want you can try to use Indeterminate Progress Bar Example and remove setWebChromeClient try this code :

public class WebViewActivityFragment extends Fragment {

 public WebViewActivityFragment() {
 }

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    //return inflater.inflate(R.layout.fragment_web_view, container, false);

    View v = inflater.inflate(R.layout.fragment_web_view, container, false);

    final String url = "https://buchung.salonmeister.de/ort/301655/menue/#offerId=907601&venueId=301655";//"https://google.com.vn";
    final ProgressBar progressBar = (ProgressBar)v.findViewById(R.id.progressBar);
    progressBar.setMax(100);
    progressBar.setVisibility(View.GONE);
    final TextView titleView = (TextView)v.findViewById(R.id.titleView);
    WebView mWebView = (WebView) v.findViewById(R.id.webView);
    mWebView.setInitialScale(1);
    mWebView.getSettings().setLoadWithOverviewMode(true);
    mWebView.getSettings().setUseWideViewPort(true);
    mWebView.getSettings().setJavaScriptEnabled(false);
    mWebView.getSettings().setAllowFileAccess(true);
    mWebView.getSettings().setAllowContentAccess(true);
    mWebView.setScrollbarFadingEnabled(false);
    mWebView.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            return false;
        }

         @Override
        public void onPageFinished(WebView view, String url) {
         progressBar.setVisibility(View.GONE);
         progressBar.setProgress(100);
         super.onPageFinished(view, url);
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
         progressBar.setVisibility(View.VISIBLE);
         progressBar.setProgress(0);
         super.onPageStarted(view, url, favicon);
        }
    });


    mWebView.loadUrl(url);

    return v;
}

}

Your URL is https so It's ssl problem.

You can find a solution in other question.

mWebView.setWebViewClient(new WebViewClient() {

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }

    @Override
    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
        handler.proceed(); // Ignore SSL certificate errors
    }
});
