Did you added the internet permission in your manifest file ? if not add the following line.
<uses-permission android:name="android.permission.INTERNET"/>
hope this will help you.
EDIT
Use the below lines.
public class WebViewDemo extends Activity {
private WebView webView;
Activity activity ;
private ProgressDialog progDailog;
@SuppressLint("NewApi")
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
activity = this;
progDailog = ProgressDialog.show(activity, "Loading","Please wait...", true);
progDailog.setCancelable(false);
webView = (WebView) findViewById(R.id.webview_compontent);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.setWebViewClient(new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
progDailog.show();
view.loadUrl(url);
return true;
}
@Override
public void onPageFinished(WebView view, final String url) {
progDailog.dismiss();
}
});
webView.loadUrl("http://www.teluguoneradio.com/rssHostDescr.php?hostId=147");
}
}
