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?

  • Do you have access to UiEngine or UiApplication instances from your application? IE, does it extend UiApplication or communicate with a foreground app that can reference a UiApplication? – Ken Gentle Nov 21 '08 at 16:31
  • yes I can reference UiApplication. But, if possible, I'd like a solution that works in both cases...just in case... – devguy Nov 21 '08 at 17:08

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);      
    }

If you know the dialog is there, and is the topmost dialog, the EventInjector APIs might do it - net.rim.device.api.system.EventInjector. When you know the dialog is there, send a KeyEvent with an ESCAPE keycode. That API is usually locked out in most enterprise environments though...

Disclaimer: I haven't tried it myself, I'd be a little surprised if it worked, since that might mean you could also dismiss the 'Allow This Connection' dialog, which would be a security hole.

This should work:

UiApplication.getUiApplication().invokeLater(new Runnable(){
  public void run(){
    UiApplication.getActiveScreen().close();
  }
});
