Resolve the problem that events in iframe within webview are unavailable

Recently do Android Webview development, use iframe embedded a lot of pages, embedded pages are not available, finally found is

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

Do not override

shouldOverrideUrlLoading

Overriding this method will intercept events in ifame.

Additional knowledge: Android native WebView access using iFrame web page problem (page can't be found)

Question:

The project uses native WebView to visit the webpage using iFrame. The list page uses iFrame to jump to Taobao Guest's address, and it can be opened by visiting Taobao Guest's address alone. However, when the list page jumps, it always prompts "the page can't be found". After trying many methods, it is finally found that WebView supports the third party Cookie.

Resolve:

if (android.os.Build.VERSION.SDK_INT > = Build.VERSION_CODES.LOLLIPOP)
CookieManager.getInstance().setAcceptThirdPartyCookies(mWebView, true);

Full configuration:

  mWebView.setWebViewClient(new WebViewClient() {
   @Override
   public void onPageStarted(WebView view, String url, Bitmap favicon) {
    super.onPageStarted(view, url, favicon);
   }

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

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

   @TargetApi(Build.VERSION_CODES.LOLLIPOP)
   @Override
   public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
    return super.shouldInterceptRequest(view, request);
   }

   @Override
   public void onPageFinished(WebView view, String url) {
    super.onPageFinished(view, url);
    if (null != title && null != view && TextUtils.isEmpty(mTitle))
     title.setText(view.getTitle());
   }
  });
  mWebView.setWebChromeClient(new WebChromeClient() {
          @Override
          public void onProgressChanged(WebView webView, int i) {
           super.onProgressChanged(webView, i);
          }

          @Override
          public boolean onJsConfirm(WebView view, String url, String message, android.webkit.JsResult result) {
           return super.onJsConfirm(view, url, message, result);
          }
