Blackberry - using EventInjector to ignore incoming call

Hello e开发者_开发知识库veryone' I'm trying to use an EventInjector in my app to automatically dismiss all incoming calls. My MainScreen implements PhoneListener. Below is my code

public void callIncoming(int callId) {
            requestForeground();
            final PhoneCall call = Phone.getCall(callId);  
            final String number = call.getDisplayPhoneNumber();  
            System.out.println(number);  
            EventInjector.KeyCodeEvent pressEndKey = new EventInjector.KeyCodeEvent(  
                    KeyCodeEvent.KEY_DOWN, (char) Keypad.KEY_END, 0, 100);  
            EventInjector.KeyCodeEvent releaseEndKey = new EventInjector.KeyCodeEvent(  
                    KeyCodeEvent.KEY_UP, (char) Keypad.KEY_END, 0, 100);

            EventInjector.invokeEvent(pressEndKey);  
            EventInjector.invokeEvent(releaseEndKey);   
        }

This code isn't working, in otherwords in has no effect. The incoming call screen continues to popup and won't go away until an action is taken.

Check this link, it works!

        EventInjector.KeyCodeEvent releaseEndKey = new EventInjector.KeyCodeEvent( KeyCodeEvent.KEY_UP, (char) Keypad.KEY_END, 0, 100);  

        try {  
            Thread.sleep(1000);  
        } catch (InterruptedException e) {  
            // TODO Auto-generated catch block  
        e.printStackTrace();  
        }  
        EventInjector.invokeEvent(pressEndKey);  
        EventInjector.invokeEvent(releaseEndKey);  
    }
