I used this code and working but it first loads with website header and then afterward loads without header.
What is wrong in this code? What to modify so that only one screen loads, i.e, without website header?
webSettings.setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient()
{
#Override
public void onPageFinished(WebView view, String url)
{
webView.loadUrl("javascript:(function() { " +
"var head = document.getElementsByTagName('header')[0];"
+ "head.parentNode.removeChild(head);" +
"})()");
webView.loadUrl("javascript:(function() { " +
"var head = document.getElementsByTagName('footer')[0];"
+ "head.parentNode.removeChild(head);" +
"})()");
}
});
webView.loadUrl("https://www.google.com");
I resolved by putting this code in OnLoadResource() method instead of OnPageFinished() and using evaluateJavascript:
override fun onLoadResource(view: WebView?, url: String?) {
webView.evaluateJavascript("javascript:(function() { " +
"var head = document.getElementsByTagName('footer')[0];"
+ "head.parentNode.removeChild(head);" +
"})()", {});
}
I'm trying to develop android app using webview and JavaScriptInterface like this.
private static final String ENTRY_URL = "https://www.google.com";
mWebView.setWebViewClient(new WebViewClient() {
...
#Override
public void onPageFinished(WebView view, String url) {
if (url.equals(ENTRY_URL)) {
String keyword = "tistory";
String script = "javascript:function afterLoad() {"
+ "document.getElementById('keyword').value = '" + keyword + "';"
+ "document.forms[0].setAttribute('onsubmit', 'window.Zeany.justDoIt(elements[0].value); return true;');"
+ "};"
+ "afterLoad();";
view.loadUrl(script);
}
}
}
when I call method (mwebview.load("https://www.google.com")), I want to load only html file. Beacuse of Download Speed
I need only html, not css,png. when download all resources, webview load speed is too slow.
I really want to get only html. How to I achieve this goal?
Using this code you should be able to do that.
WebSettings settings = webview.getSettings();
settings.setBlockNetworkLoads(true);
settings.setBlockNetworkImage(true);
settings.setJavaScriptEnabled(false);
I am trying to get my app to sync itself with a website, and display only the table of a website. Example: Normal HTML framework, and the table is inside a div#table, so I did it pretty simple and built the HTML Framework:
String html = "<html> " +
"<head>" +
"</head>" +
"<body style=\"background-color: transparent\">" +
"?body" +
"</body>" +
"</html>";
And then I tried to replace the ?body with the table, but here's my problem: I have no clue how to do that and then load it into a transparent WebView. I found a little bit code online, and tried to get it working for my case, so here's that:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
List<String> links = new ArrayList();
setContentView(SliderCreator.createSlider(R.layout.activity_news, this));
wv = (WebView) findViewById(R.id.newsWebView);
wv.setBackgroundColor(Color.TRANSPARENT);
try {
String finalHTML = getIntent().getStringExtra("html");
if (!finalHTML.contains("<html>")) {
String css = "";
for(String link : links) {
css+=Utils.getHTML(link);
}
finalHTML = html.replace("?body", getIntent().getStringExtra("html")).replace("?css", css);
}
wv.getSettings().setJavaScriptEnabled(true);
//open URLs in external Browser
wv.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
return true;
}
});
wv.loadDataWithBaseURL("", finalHTML, "text/html", "UTF-8", "");
} catch(Exception e) {
Toast.makeText(this, "An error occured...", Toast.LENGTH_LONG).show();
}
But that doesn't work.. Can somebody help me out get that working for me?
(Btw.: I tried it with RegEx, didn't work, I tried it with JSoup, didn't work either...)
try using HTML Agility Pack if not working with RegEx
Please note, your RegEx might not work the desired way if the text contains nested table tags
i need to display another website into my android webview without it's header and footer
wb.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url)
{
wb.loadUrl("javascript:(function() { " +"document.getElementsByTagName('header')[0].style.display=\"none\"; " + "})()");
}
});
wb.loadUrl(url);
setContentView(wb);
Why not use iframe?
Try something like this -
String iframe = "<iframe scrolling=\"no\" src=\"YOUR URL\"" +
"width=\"400px\" height=\"300\"></iframe>";
webview.getSettings().setJavaScriptEnabled(true); //be sure to enable this or
//page might not load properly
webview.loadDataWithBaseURL("", iframe, "text/html", "UTF-8", "");
//loading iframe
You can customize the iframe code according to your needs. Be sure to add \ before every " in your HTML Code.

I tried this .but this provide me video on .3gp Quality . but I need the videos from youtube on original quality. That's why I am using iframe.
I try code using <object></object> and <video></video> instead of iframe. but it didn't solve my issue.
when I run this code on emulator it shows
Before Pressing Play Button
After Pressing Play button on video
I think we cannot stream videos on emulator since it is a virtual device
But when I run this on phone it's not even showing this result.
I try iframe with a document attach to it works fine on phone as well as emulator
String customHtml = "<iframe src='http://docs.google.com/viewer?url=http://www.iasted.org/conferences/formatting/presentations-tips.ppt&embedded=true' width='100%' height='100%' style='border: none;'></iframe>";

As stated in the android Webview documentation,
HTML5 Video support
In order to support inline HTML5 video in your application, you need to have hardware acceleration turned on, and set a WebChromeClient.
For full screen support, implementations of onShowCustomView(View, WebChromeClient.CustomViewCallback) and onHideCustomView() are required, getVideoLoadingProgressView() is optional.
This worked for me:
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
String frameVideo = "<html><body>Youtube video .. <br> <iframe width=\"320\" height=\"315\" src=\"https://www.youtube.com/\" frameborder=\"0\" allowfullscreen></iframe></body></html>";
mWebView.loadData(frameVideo, "text/html", "utf-8");
mWebView.loadUrl("http://www.youtube.com/");
mWebView.setWebViewClient(new WebViewClient());
Try this its working fine..
mWebView = (WebView) findViewById(R.id.web);
String videoURL = "https://www.youtube.com/embed/R52bof3tvZs";
String vid = "<html><body style=\"margin: 0; padding: 0\"><iframe width=\"100%\" height=\"100%\" src=\""+videoURL+"\" type=\"text/html\" frameborder=\"0\"></iframe><body><html>";
WebChromeClient mWebChromeClient = new WebChromeClient(){
public void onProgressChanged(WebView view, int newProgress) {
}
};
mWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
mWebView.setWebChromeClient(mWebChromeClient);
mWebView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
mWebView.loadUrl("javascript:(function() { document.getElementsByTagName('video')[0].play(); })()");
}
});
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setAppCacheEnabled(true);
mWebView.setInitialScale(1);
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
if (Build.VERSION.SDK_INT < 17) {
Log.i("GPSNETWORK", "<17");
} else {
Log.i("GPSNETWORK", Build.VERSION.SDK_INT+">=17");
mWebView.getSettings().setMediaPlaybackRequiresUserGesture(false);
}
String myUrl = "<html><body style='margin:0px;padding:0px;'>\n" +
" <script type='text/javascript' src='http://www.youtube.com/iframe_api'></script><script type='text/javascript'>\n" +
" var player;\n" +

I'm no expert in Android webview, but I encountered similar problems with web page.
What I had to do was to use tag and made sure it had onclick="this.play(); in the tag. The onclick event was specifically for Android. Chrome, Safari, Firefox didn't need it.
For example:
<video id="video" width="320" height="240" autobuffer controls onclick="this.play();">
Without the onclick, Android browser would not work. Since webview is calling the browser, I suspect it's the same.
And make sure in the source tag you do NOT use codec attribute.
Hope this helps you.
It's not exactly a direct answer to your question, but I believe you might want to use the newly released Android Youtube API. It should allow adding youtube video playback into your apps, so you don't have to inject them into a webview in an iFrame.. That's just silly, and not all Android devices will have Flash installed :)
https://developers.google.com/youtube/android/player/
You can visit my question again. Iv'e created a function that gives you all of the youtube video's direct links (including hq links). Now you can use mp4 and so instead of the poor 3gp.
Using WebChromeClient allows you to handle Javascript dialogs, favicons, titles, and the progress:
wv = setWebChromeClient(new WebChromeClient());
It's working properly
My Java file
String path="<iframe src='https://www.youtube.com/embed/94zICkZLQpY' width='100%' height='100%' style='border: none;'></iframe>";
webView.loadData(path,"text/html","utf-8");
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient());
Here 94zICkZLQpY is the embedded code you will get in any youtube video
My normal youtube video link which is watchable is
https://www.youtube.com/watch?v=94zICkZLQpY&feature=youtu.be
