Android webview Load url doesn't work for Instagram webpage

I realized that not working for under android 4.3 versions.
I have an android app which has webview. When i try to load url "http://instagram.com" it's not working It shows blank page but facebook webpage is working.
It's really important for me please help.
WebView view = (WebView) findViewById(R.id.webView1);
view.getSettings().setJavaScriptEnabled(true);
view.loadUrl("http://www.instagram.com");

Have you tried using the method:
setDomStorageEnabled();
Sets whether the DOM storage API is enabled. The default value is
false.
for example:
WebView view = (WebView) findViewById(R.id.webView1);
view.getSettings().setJavaScriptEnabled(true);
view.getSettings().setDomStorageEnabled(true);
view.loadUrl("http://www.instagram.com");
I had previously problems loading Facebook and Twitter pages in some devices, solved using setDomStorageEnabled() method.

Android Webview doesn't load

I have a problem with Android Web view.
The slider work fine with Apple but doesn't load on Android WebView.
Can anyone help? www.pgc-usa.net/ivynails
Thanks

I think I know. Web views in Android by default do not have JavaScript enabled. This is because there is someway it can do harm to the app. To enable it though it takes two lines
WebSettings webSettings = yourWebview.getSettings();
yourWebview.setJavaScriptEnabled(true);
You can also set it so that links that are clicked open in the web view. ( Otherwise they open in browser.) to add this you just add
yourWebview.setWebViewClient(new WebViewClient());
All that together will make it come to this:
WebView yourWebview = (WebView) findViewById(R.id.myWebview);
yourWebview.loadUrl("http://www.pgc-usa.net/ivynails");
WebSettings webSettings = yourWebviewgetSettings();
webSettings.setJavaScriptEnabled(true);
yourWebview.setWebViewClient(new WebViewClient());

Android Webview for videosteams?

I am using a webview to connect to an ip camera. It works when I need snapshots , but i get a white screen when I try to get videostreams. I tried .getPlugins as well. What could be the possible reason?
mWebView = (WebView) findViewById(R.id.webView1);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://<ipaddress>/videostream.cgi?user=&pwd=");

you can call Browser activity and set specific URL by intent. Take a look here: Sending an Intent to browser to open specific URL

How to open a PDF file from server in android

I have a requirement where there is a URL = "http://www.example/Open.pdf"
Now from my android application I want to open this PDF file directly in the default PDF viewer.
The moment I click on this link on the webpage, user should be presented with a default PDF viewer opened with this document.
Note: This file should not be stored on the SD card.
How do I proceed for this implementation?

We can open PDF file in the webview without caching it. Write below code in "onCreate" method .
Working code :
String url = "http://www.example.com/abc.pdf";
final String googleDocsUrl = "http://docs.google.com/viewer?url=";
WebView mWebView=new WebView(this);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setPluginsEnabled(true);
mWebView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url){
view.loadUrl(url);
return false; // then it is not handled by default action
}
});
mWebView.loadUrl((googleDocsUrl + url));
setContentView(mWebView);
What happens here is you open the PDF using Google Docs. Best Advantage of using above method is the lazy loading of PDF. Does not matter how heavy the PDF is. Google Docs takes care of it.

You can view the pdf in the WebView using googleDocs.
WebView webView = (WebView) findViewById(R.id.my_webview);
webView.setWebViewClient(new MyWebViewClient());
webView.addView(webView.getZoomControls());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://docs.google.com/gview?embedded=true&url=http://myurl.com/demo.pdf");

There is no way you can open a default PDF view from your application.
If your file is on the server and you want to open it without downloading then this might also pose a greater security concern. If external applications like default adobe reader can access the content on your server, then this is breaking the security framework altogether.
So, best option would be to launch a new instance of browser or webview and show the PDF document in google docs to the user.
This way user can read the document and get back to the recent state of the application as well.

You can view the pdf in the WebView using googleDocs.
WebView webView = (WebView) findViewById(R.id.my_webview);
webView.setWebViewClient(new MyWebViewClient());
webView.addView(webView.getZoomControls());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://docs.google.com/gview?embedded=true&url=http://myurl.com/demo.pdf");
do you have the others solution besides view pdf file using http://docs.google.com/gview?embedded=true&url=http://myurl.com/demo.pdf

WebView Problem on Youtube site in Android?

i tried to load the url ww.youtube.com on my app in a webview. but it cant be load completely. it loads just like below image. in the browser it loads comfortably. why? Any Idea?
image http://www.freeimagehosting.net/uploads/d7356dd8e1.png

the simple answer is to call the youtube app thats loaded on every phone with your webview. check out the code on http://fluxkore.com/index.php/android-apps/ to call the youtube app.....

Enable JavaScript! =)
myWebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.loadUrl("http://www.youtube.com");

It might be a problem with WebViews - WebViews aren't fully fledged browsers, and have limited functionality. For example, the reference page specifically says that WebViews don't handle JavaScripts. If JavaScripts, Flash or something like that is required to properly load YouTube, then that could be why the WebView doesn't handle it properly.
