public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
progressBar=(ProgressBar)findViewById(R.id.progressbar);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setSavePassword(false);
mWebView.getSettings().setSaveFormData(false);
progressBar.setVisibility(ProgressBar.GONE);
mWebView.setWebChromeClient(new WebChromeClient()
{

});
mWebView.setWebViewClient(new WebViewClient()
{
public boolean shouldOverrideUrlLoading(WebView view, String url)
{


view.loadUrl (url);
//mWebView.loadData("", "text/html", "utf-8");
return false;
}
