    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_my, container, false);

        mWebView = (AdvancedWebView) rootView.findViewById(R.id.webview);
        mWebView.setListener(this, this);
        mWebView.loadUrl("http://www.example.org/");

• Receive callbacks when pages start/finish loading or have errors

  @Override
  public void onPageStarted(String url, Bitmap favicon) {
     // a new page started loading
  }
  
  @Override
  public void onPageFinished(String url) {
     // the new page finished loading
  }
  
  @Override
  public void onPageError(int errorCode, String description, String failingUrl) {
     // the new page failed to load
  }
  

• Downloads are handled automatically and can be listened to

  @Override
  public void onDownloadRequested(String url, String userAgent, String contentDisposition, String mimetype, long contentLength) {
     // some file is available for download
     // either handle the download yourself or use the code below
  
     final String filename;
     // ...
  
     if (AdvancedWebView.handleDownload(this, url, filename)) {
         // download successfully handled
     }
     else {
         // download couldn't be handled because user has disabled download manager app on the device
         // TODO show some notice to the user
     }
  }
  

• Enable geolocation support (needs <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />)

  mWebView.setGeolocationEnabled(true);
  

• Add custom HTTP headers in addition to the ones sent by the web browser implementation

  mWebView.addHttpHeader("X-Requested-With", "My wonderful app");
  

• Define a custom set of permitted hostnames and receive callbacks for all other hostnames

  mWebView.addPermittedHostname("www.example.org");
  

  and

  @Override
  public void onExternalPageRequest(String url) {
     // the user tried to open a page from a non-permitted hostname
  }
  

• Prevent caching of HTML pages

  boolean preventCaching = true;
  mWebView.loadUrl("http://www.example.org/", preventCaching);
  

• Check for alternative browsers installed on the device

  if (AdvancedWebView.Browsers.hasAlternative(this)) {
     AdvancedWebView.Browsers.openUrl(this, "http://www.example.org/");
  }
  

• Disable cookies

  // disable third-party cookies only
  mWebView.setThirdPartyCookiesEnabled(false);
  // or disable cookies in general
  mWebView.setCookiesEnabled(false);
  

• Disallow mixed content (HTTP content being loaded inside HTTPS sites)

  mWebView.setMixedContentAllowed(false);
  

Dependencies
