How to make a WebView Load fast And adding a Progress bar to it

Question

I am making a simple application in which I have put a webview, but the page is loading very slow(tried with many websites) and also I want to add a progress bar so it should show that the page is loading. Here is the code I am using for webview but I have no idea how to get progress bar on it:

public class MainActivity extends Activity {

WebView wv;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    wv = (WebView) findViewById(R.id.webView1);
    wv.setWebViewClient(new webCont());

    wv.loadUrl(" http://www.abc.com" ); 
}
 class webCont extends WebViewClient
{

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

        return true;
    }
}

Have a progress bar. Display the same. You customize the below to suit your needs. To load faster it depends on the connection speed.

Override onPageFinished and set the visibility to gone in webcount

public class MainActivity extends Activity {
    /** Called when the activity is first created. */

    WebView web;
    ProgressBar progressBar;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        web = (WebView) findViewById(R.id.wv);
        progressBar = (ProgressBar) findViewById(R.id.progressBar);
        web.setWebViewClient(new myWebClient());
        web.getSettings().setJavaScriptEnabled(true);
        web.loadUrl("http://slashdot.org/");
    }

    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;

        }
        @Override
        public void onReceivedError(WebView view, int errorCode,
                String description, String failingUrl) {
            // TODO Auto-generated method stub
             Toast.makeText(MainActivity.this, "Oh no! " + description, Toast.LENGTH_SHORT).show();
            //super.onReceivedError(view, errorCode, description, failingUrl);
        }
        @Override
        public void onPageFinished(WebView view, String url) {
            // TODO Auto-generated method stub
            super.onPageFinished(view, url);

            progressBar.setVisibility(View.GONE);
        }
    }

    // To handle "Back" key press event for WebView to go back to previous screen.
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) 
    {
        if ((keyCode == KeyEvent.KEYCODE_BACK) && web.canGoBack()) {
            web.goBack();
            return true;
        }
        else
        {
            finish();
            return true;
        }
    }
}

xml

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <WebView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_above="@+id/button1"
        android:id="@+id/wv"/>
    <ProgressBar
       android:id="@+id/progressBar"
       android:layout_width="wrap_content"
       android:layout_centerInParent="true"
       android:layout_height="wrap_content"
       />


</RelativeLayout>
