Question

I have a BlackBerry app running in the background that needs to know when a “Missed call” system dialog is brought up by the system, and programmatically close it without user intervention. How can I do that?

I could actually almost know when the dialog is brought up, i.e. a little later I programmatically end the call…but how can I get a reference to the dialog, and close it?

Answer 1

Key press injection for device Close button looks like this:

KeyEvent inject = new KeyEvent(KeyEvent.KEY_DOWN, Characters.ESCAPE, 0);
inject.post();

Don’t forget to set permissions for device release:
Options => Advanced Options => Applications => [Your Application] =>Edit Default permissions =>Interactions =>key stroke Injection

Code sample:

class Scr extends MainScreen implements PhoneListener {
    public Scr() {
        Phone.addPhoneListener(this);
    }

    public boolean onClose() {
        Phone.removePhoneListener(this);
        return super.onClose();
    }

    public void callDisconnected(int callId) {
        Timer timer = new Timer();
        timer.schedule(new TimerTask(){public void run() {
            KeyEvent event = new KeyEvent(KeyEvent.KEY_DOWN,  
                        Characters.ESCAPE, 
                        KeyListener.STATUS_NOT_FROM_KEYPAD);
            event.post();
        }}, 1000);      
    }
