Blackberry java app running in background

I would like to exit the application with 2 different ways: - When key "escape" pressed, the application exit but still run in background. - When the user select "Close" in the menu to close the application totally. This is already working as it is the default behavior.

In my MainScreen class, I have 开发者_运维百科overwritten the close() method that call super.close() at the end in order to close the screen.

Thank you
