protected void destroyApp(boolean arg0) throws MIDletStateChangeException {


}

protected void pauseApp() {

}

protected void startApp() throws MIDletStateChangeException {
Application.getApplication().addKeyListener(this);
display=Display.getDisplay(this);
this.canvas=new MyCanvas();
display.setCurrent(canvas);

import javax.microedition.lcdui.Canvas;
import javax.microedition.lcdui.Graphics;
public class MyCanvas extends Canvas{

protected void paint(Graphics g) {
g.setColor(255,255,255);
g.fillRect(0, 0, getWidth(), getHeight());
g.setColor(0,0,0);
