Blacberry Splash Screen

1.Code For Splash Screen is

package mypackage;

import java.util.Timer;
import java.util.TimerTask;

import net.rim.device.api.system.Bitmap;
import net.rim.device.api.system.Display;
import net.rim.device.api.ui.Graphics;
import net.rim.device.api.ui.container.MainScreen;
 
public class SplashScreen extends MainScreen {
 
    Bitmap popup;
    SplashScreen screen = this;
    private Timer splashTimer = new Timer();
    private TimerTask splashTask;
    int count = 0;
    int screenWidth = Display.getWidth();
    int screenHeight = Display.getHeight();
    int yCoord;
    int xCoord;
    boolean showSplash = true;
    boolean splashDisplayed = false;
 
    public SplashScreen(Bitmap popup, final int seconds) {
        this.popup = popup;
        xCoord = (screenWidth - popup.getWidth()) / 2;
        yCoord = (screenHeight - popup.getHeight()) / 2;
 
        splashTask = new TimerTask() {
 
            public void run() {
                if (showSplash && !splashDisplayed) {
                    count++;
                    if (count == seconds * 10) {
                        showSplash = false;
                        splashDisplayed = true;
                        splashTimer.cancel();
                        invalidate();
                    }
                }
            }
        };
 
        splashTimer.scheduleAtFixedRate(splashTask, 100, 100);
 
    }
 
    protected void paint(Graphics graphics) {
        super.paint(graphics);
        if (showSplash && !splashDisplayed) {
            graphics.drawBitmap(xCoord, yCoord, popup.getWidth(), popup.getHeight(), popup, 0, 0);
            //draw border, delete if not needed:
            //graphics.setColor(0xcccccc);
            //graphics.drawRect(xCoord, yCoord, popup.getWidth(), popup.getHeight());
        }
    }
 
    protected void onUiEngineAttached(boolean attached) {
        showSplash = true;
        invalidate();
        super.onUiEngineAttached(attached);
    }
 
    //allow user to dismiss splash screen:
    protected boolean navigationMovement(int dx, int dy, int status, int time) {
        return DismissSplash();
    }
 
    protected boolean navigationClick(int status, int time) {
        return DismissSplash();
    }
 
    protected boolean keyChar(char c, int status, int time) {
        return DismissSplash();
    }
 
    private boolean DismissSplash() {
        if (showSplash) {
            showSplash = false;
            splashDisplayed = true;
            invalidate();
            return true;
        }else{
            return false;
        }
    }
}

2. In applications Entry point screen extends SplashScreen & call to Super as shown bellow

package mypackage;

import net.rim.device.api.system.Bitmap;
import net.rim.device.api.system.Display;
import net.rim.device.api.ui.Field;
import net.rim.device.api.ui.FieldChangeListener;
import net.rim.device.api.ui.UiApplication;
import net.rim.device.api.ui.component.ButtonField;

/**
 * A class extending the MainScreen class, which provides default standard
 * behavior for BlackBerry GUI applications.
 */
public final class MyScreen extends SplashScreen
{
    /**
     * Creates a new MyScreen object
     */
 
    public MyScreen()
    {      
        super(ImageResize.resizeBitmap(Bitmap.getBitmapResource("thepopup.png"), Display.getWidth(), Display.getHeight()), 5);
        setTitle("This IS Main First Screen After SplashScreen");
        
    }
    
}
