How to hide the icon of autostartup program in 'Switch application' menu?

Hi everybody!

Please help me solve this problem. I created the program look like the 'notificationdemos' application in Blackberry sample codes. I need some resources must be available first so i push some codes in autostartup as follow:


public static void main(String[] args) { if (args.length > 0 && args[0].equals("autostartup")) {


     MessageNotifications mn =
new MessageNotifications();



     // Keep this instance around for rendering

     // Notification dialogs.






 The program runs well except that when i want to switch to another application, I can see the icon of autostartup program. And if i click on it, the system hangs. I don't want to show this icon. Is there any way to hide it?

Thanks in advance

Does your application has a GUI?

As mantaker is probably going to suggest, if your application does not have a GUI, then you can extend Application, rather than UiApplication.  However if your application does things that require GUI interaction, such as network connections that may require the 'allow' popup, then this is not an option.  In this case, this Post from Mark Sohm will help.


hiding application?



To summarize, you can override




and return false when you don't want your application to be be seen.  Never tried it myself, but don't see why it would not work.
