Does anyone have the idea to programmatically detect if the Lock Scrren is shown? I want to detect this screen so my application could do special Notifications.

Thanks fro your helps.

You might try MemoryCleanerListener. You get a deviceLocked event when the screen is locked.

Thanks very much. My application just want to detect if the Lock Scrren is shown, but do not care this event (EVENT_DEVICE_LOCK).

The ApplicationManager.isSystemLocked method can be used to determine if the BlackBerry is locked.

Anyone have successed with that code?
I still get the problem with it, this is my code, 

public static void main(String[] args)
    {
        MakeMeAPrincessApp theApp = new MakeMeAPrincessApp();       
        theApp.enterEventDispatcher();
        
        
      	MemoryCleanerDaemon.addListener(new MemoryCleanerListener() {
			public String getDescription() {
				// TODO Auto-generated method stub
				return "listener";
			}
			
			public boolean cleanNow(int event) {
				// TODO Auto-generated method stub
				System.out.println("running");
				if(event==MemoryCleanerListener.EVENT_DEVICE_LOCK){
					System.out.println("LOCK");
				}else{
					System.out.println("UNLOCK");
				}
				
				return false;
			}
		});
    }

 please anyone can help me?

Hi @MalaWidiyanto

The function "enterEventDispatcher" does not return so you should add your listener (and all your code) before you call it.

hi @maadani thank for replay  
I have try to place the "listener" before "enterEventDispatcher" but its look doesn't work, 
do you have solution for this problem?

[maadani]

Can you post your updated code?

What exactly happen when you are trying to debug your code?

Any errors in the log?

E.

@maadani
this is my new code :

public static void main(String[] args)
    {
    	
    	MemoryCleanerDaemon.addListener(new MemoryCleanerListener() {			
			public boolean cleanNow(int event) {
				// TODO Auto-generated method stub
				System.out.println("running");
				if(event==MemoryCleanerListener.EVENT_DEVICE_LOCK){
					System.out.println("LOCK");
					Dialog.inform("LOCK");
				}else{
					System.out.println("UNLOCK");
				}
				
				return false;
			}

			public String getDescription() {
				// TODO Auto-generated method stub
				return "listener";
			}
		});
    	
      	MakeApp theApp = new MakeApp();       
        theApp.enterEventDispatcher();
    }

 but not successed yet, whats wrong with my code?
or I must try it in the device? I just tested it on Simulator

and no an error in the log ...
