Android WebView not loading URL

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");

           }
    }

Add Permission Internet permission in manifest.

as <uses-permission android:name="android.permission.INTERNET"/>

This code it working

  public class WebActivity extends Activity {
  WebView wv;

 String url="http://www.teluguoneradio.com/rssHostDescr.php?hostId=147";

 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_web);
    wv=(WebView)findViewById(R.id.webUrl_WEB);



WebSettings webSettings = wv.getSettings();
    wv.getSettings().setLoadWithOverviewMode(true);
    wv.getSettings().setUseWideViewPort(true);
    wv.getSettings().setBuiltInZoomControls(true);
    wv.getSettings().setPluginState(PluginState.ON);


    wv.setWebViewClient(new myWebClient());

    wv.loadUrl(url);
}




public class myWebClient extends WebViewClient {
    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        // TODO Auto-generated method stub
        super.onPageStarted(view, url, favicon);
    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        // TODO Auto-generated method stub

        view.loadUrl(url);
        return true;

    }
}
