midlet game canvas : cobain deh...

package GameCanvasPackage;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class MidletGameCanvas extends MIDlet {
private Display display;

public void startApp() {
display = Display.getDisplay(this);
DrawGameCanvas gameCanvas = new DrawGameCanvas();
gameCanvas.start();
display.setCurrent(gameCanvas);
}

public Display getDisplay() {
return display;
}

public void pauseApp() {}

public void destroyApp(boolean unconditional) {
exit();
}

public void exit() {
System.gc();
notifyDestroyed();
}
}

semoga berhasil...
