I have a webview. Everything is working fine but when I am opening a page which has iframe, the iframe is not getting visible. Are there any specific settings required?

- Increased resources required to enable hardware acceleration, so try adding it to activity label or application label in manifest .Shree Krishna– Shree Krishna2016-01-19 08:43:50 +00:00Commented Jan 19, 2016 at 8:43

First add Hardware Acceleration and add the following lines to your webView
webView.setWebChromeClient(new WebChromeClient()); EDIT 1
It will be hard to identify the problem but try adding WebChromeClient, WebViewClient and also don't forget to enable javascript before loading URL like this
webView= (WebView) findViewById(R.id.webview); webView.setWebChromeClient(new WebChromeClient()); webView.setWebViewClient(new WebViewClient()); webView.getSettings().setJavaScriptEnabled(true); EDIT 2
If you really need to load content of iframe then Try using Jsoup to load html page but you have to find the iframe and fetch the content manually.
Document doc=... Element iframe1 = doc.select("#iframe1").first(); if (iframe1!=null) { Document iframeContent = Jsoup.connect(iframe1.attr("src")).get(); } where iframe1 is id of your iframe.

Why is hardware accelaration necessary?
Shree Krishna
@mohanmishra as I see many standard browsers and apps uses hardware-accelerated 2D graphics since long before. The main benefit is only extra boost in performance. It is recommended.

This maybe a too late answer! I hope it will help someone.
Just try to set up a desktop user agent to your webview
String DESKTOP_USER_AGENT = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2049.0 Safari/537.36"; webView.getSettings().setUserAgentString(DESKTOP_USER_AGENT);

If you modify webview configurations and use loadData function to load iframe, some iframes will not work in webview. So for the solution I have implemented AdvancedWebView library.
https://github.com/delight-im/Android-AdvancedWebView
Use loadHtml(URL) method with this webview and you can pass URL in parameter and you will be able to view iframe in webview.

Only thing that works for me, in Manifest:
android:hardwareAccelerated="true" and in your Activity:
webView.getSettings().setDomStorageEnabled(true); Comments
Can you check if you have
android:hardwareAccelerated="true" in your AndroidManifest file, in the <application> tag of that activity.

following hack worked for me for loading iframes in webview.Hope some one still might find it useful
String webContent="your data to be loaded in webview"; if(webContent.contains("iframe")){ Matcher matcher = Pattern.compile("src=\"([^\"]+)\"").matcher(webContent); matcher.find(); String src = matcher.group(1); webContent=src; try { URL myURL = new URL(src); webView.loadUrl(src); } catch (MalformedURLException e) { e.printStackTrace(); } }else { webView.loadDataWithBaseURL(null, "<style>img{display: inline;height: auto;max-width: 100%;}</style>" + webContent, "text/html", "UTF-8", null);} } } Also do not forget to add Internet permission in your manifest file.
<uses-permission android:name="android.permission.INTERNET" />
