After splashscreen, a white blank screen comes and then webview is loaded

In my app, there are two activities.First is Splashscreen and second is Webview activity. After splash screen displays,i want to show my webview activity.But after splashscreen,for 2-3 seconds a blank white screen comes and then webview activity gets loaded.Any idea of how to ignore this white screen. I looked into the solution for this issue in many posts but without success. Any help will be appreciated.

Adding the code : Splashscreen Activity :

@Override
protected void onStart() {
    super.onStart();
    new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            finish();
            startActivity(new Intent(SplashScreen.this,
                    WebViewActivity.class));
        }
    }, DELAY);
}

Working code

public class WebActivity extends Activity {

protected boolean _active = true;

protected int _splashTime = 3000;

Thread splashTread;

private boolean stop = false;

/** Called when the activity is first created. */

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

    splashTread = new Thread() {
        @Override
        public void run() {
            try {
                int waited = 0;
                while(_active && (waited < _splashTime)) {
                    sleep(100);
                    if(_active) {
                        waited += 100;
                    }
                }

            } catch(InterruptedException e) {
                // do nothing
            } finally {

                if(!stop){
                    startActivity(new Intent(WebActivity.this,Home.class));
                    finish();
                }
                else
                    finish();
            }
        }

    };
    splashTread.start();

}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_BACK)) {

        if(splashTread.isAlive())
            this.stop = true;
    }
    return true;
}
}

create two class files like WebActivity.java,home.java.

WebActivity.java

       Handler handler = new Handler();

    // run a thread after 2 seconds to start the home screen
    handler.postDelayed(new Runnable() {

        @Override
        public void run() {

            // make sure we close the splash screen so the user won't come
            // back when it presses back key

            finish();
            // start the home screen

            ProgressDialog pd = new ProgressDialog(WebActivity.this);

            //use this before calling intent
                          pd.setMessage("Processing...");

            pd.show();



            Intent intent = new Intent(WebActivity.this, Home.class);

            WebActivity.this.startActivity(intent);

        }

    }, 2000); // time in milliseconds (1 second = 1000 milliseconds) until the run() method will be called

Home.java

   webview=(WebView)findViewById(R.id.webView1);
webview.setWebViewClient(new myWebClient());

webview.loadUrl("http://www.google.com");}

 public class myWebClient extends WebViewClient

 {

     @Override

        public boolean shouldOverrideUrlLoading(WebView view, String url) {

            // TODO Auto-generated method stub


            view.loadUrl(url);

            return true;

        }
 }

Android manifest

Just add the activity class and set internet permission to load webview
