Hello sandesh,

you should provide some more details on what you want to do.
Maybe this helps:
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1. WebView view = new WebView(something);
  2.  
  3. view.getSettings().setJavaScriptEnabled(true);
Parsed in 0.010 seconds, using GeSHi 1.0.8.4

Hello sandesh,

you are probably looking for [font=Lucida Console].loadUrl(String url);[/font]

Let us know whether you get it displayed.

Hello sandesh,

[font=Lucida Console]onCreate(...)[/font] is the very first method of your Activity, being called and in that function you cannot call this line:
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1. linearLayout.addView(webview, createParam(wc, wc));
Parsed in 0.011 seconds, using GeSHi 1.0.8.4
because webView is still null :!:

You initialize it only in [font=Lucida Console]onClick(...)[/font].
