Question

I want to come to home screen when clicking on the back button from my application in blackberry. I have searched for this in google and stackoverflow, But I didn’t get any solution. Anybody help for this.

In My Starting Screen i wrote like this for back button.

protected boolean keyDown(int keycode, int time)
    {
        if (Keypad.key(keycode) ==  Keypad.KEY_ESCAPE)
        {
            close();
            return true;
        }

        else
        {
            return super.keyDown(keycode, time);
        } 
    }

In my HomeScreen i wrote like this.

protected boolean keyDown(int keycode, int time)
    {
        if (Keypad.key(keycode) ==  Keypad.KEY_ESCAPE)
        {
            UiApplication.getUiApplication().pushScreen(new StartingScreen());
            return true;
        }

        else
        {
            return super.keyDown(keycode, time);
        } 
    }

From my application HomeScreen I am able to come to starting screen of the my application. after that when i click on back button from starting screen i need to go to blackberry home screen that means i need to exit the app and come out of that. I wrote close(); to come to blackberry home screen. but its not working. it is again coming to my application homescreen.
