Event Listeners

Extends XWalkResourceClient

class XWalkResponceClient extends XWalkResourceClient {
    public XWalkResponceClient(XWalkView view) {
      super(view);
    }

    @Override
    public void onLoadFinished(XWalkView view, String url) {
      super.onLoadFinished(view, url);
      // Finish loading
    }
   
    @Override
    public void onLoadStarted(XWalkView view, String url) {
      super.onLoadStarted(view, url);
    }

    @Override
    public void onProgressChanged(XWalkView view, int progressInPercent) {
      super.onProgressChanged(view, progressInPercent);
    }
     
    @Override
    public void onReceivedLoadError(XWalkView view, int errorCode,
        String description, String failingUrl) {
      super.onReceivedLoadError(view, errorCode, description, failingUrl);
    }

    @Override
    public void onReceivedSslError(XWalkView view,
        ValueCallback<Boolean> callback, SslError error) {
      // SSL Should use default handler
      super.onReceivedSslError(view, callback, error);
    }

    @Override
    public WebResourceResponse shouldInterceptLoadRequest(XWalkView view,
        String url) {
      return super.shouldInterceptLoadRequest(view, url);
    }

    @Override
    public boolean shouldOverrideUrlLoading(XWalkView view, String url) {
      return super.shouldOverrideUrlLoading(view, url);
    }
}

Known issues

• Locale? When accessing Facebook, Rakuten, signin page, always open English page(not local language page)
• It doesn’t have Download Feature(need to implement by ourselves)
• We have to call onReceivedSslError(if not call, the user tried to access twitter.jp which has invalid ssl certificate)
