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.

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

Internal links in WebView

I want to find out when a user clicks an internal link in a url currently opened in webview. How can I do that?
Thanks,
Farha

Try setting WebViewClient for the WebView and the onPageStarted() method will be called when the page loading is started.
Edit:
To be more clear, this may be a sample code:
WebView wview = (WebView) findViewById(R.id.webView1);
WebViewClient wvClient = new WebViewClient();
wview.setWebViewClient(wvClient);
wvClient.onPageStarted(wview, wview.getUrl(), null);

Android : How to Load PDF?

Is there any way to load PDF file from Asset/URL in Browser or WebView or any other way?

There is no native way to do this at the moment. However, you could write your own pdf viewer activity. Also, check out RepliGo Reader and PDF GView.

Instead loading PDF file from local resource, you can think about open it online using Google Docs Viewer:
WebView webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
String pdf = "http://www.adobe.com/devnet/acrobat/pdfs/pdf_open_parameters.pdf";
webview.loadUrl("http://docs.google.com/gview?embedded=true&url=" + pdf);
