Adding a progress bar to webview

Question

Hi,

I have been trying to put a back button progress bar in a webview and keep the url loading within my app instead of using the android default web browser.

If I manage to keep to browsing within the app and keep the back button the progress bar never shows up if I manage to get the progress bar to show up the code at the bottom for shouldoverideurl come up never read and the default browser launches, I tried all the google tutorials and solution but none of them work. I am currently using google.. Can anyone help??

public class livebrad extends Activity {

WebView mWebView;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);

    // Adds Progrss bar Support
    this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
    setContentView(R.layout.brows);

    // Makes Progress bar Visible
    getWindow().setFeatureInt(    Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON); 

    // Get Web view
    mWebView = (WebView) findViewById( R.id.webView ); //This is the id you gave 
                                                         //to the WebView in the main.xml
    mWebView.getSettings().setJavaScriptEnabled(true);   
    mWebView.getSettings().setSupportZoom(true);         //Zoom Control on web (You don't need this 
                                                         //if ROM supports Multi-Touch        
    mWebView.getSettings().setBuiltInZoomControls(true); //Enable Multitouch if supported by ROM

    // Load URL
    mWebView.loadUrl("http://www.bbc.co.uk");


    // Sets the Chrome Client, and defines the onProgressChanged
    // This makes the Progress bar be updated.
    final Activity MyActivity = this;
    mWebView.setWebChromeClient(new WebChromeClient() {
    public void onProgressChanged(WebView view, int progress)   
    {
        //Make the bar disappear after URL is loaded, and changes string to Loading...
        MyActivity.setTitle("Loading...");
        MyActivity.setProgress(progress * 100); //Make the bar disappear after URL is loaded

        // Return the app name after finish loading
        if(progress == 100)
            MyActivity.setTitle(R.string.app_name);

    }class HelloWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }
    });



}//End of Method onCreate
