Hi I am new to Blackberry. I am developing a Quizz application having a HomeScreen and subsequent screens.My requirement is after user exit the application in the middle of the application the user is able to continue the test where he stopped. For that I used a ResumeButton on the HomeScreen whish should display even after closing the application user wants to continue the test. Any solution appreciated..Plese specify any code snippet.Thanks in advance.

You need to think about your idea of "state" -- save state when the user exits, and then use the saved state to display the proper screen when the app starts.

At the most abstract, your code will resemble this:

  static void main(String[] args) {
    // create UI App
    customUiApp = new customUiApp();

    // read stored state - is there any?

    if (oldState) {
       // unserialize current test object

       // launch test screen with test object
    } else {
       // launch default homescreen
    }
    cutomUiApp.enterEventDispatcher();
}

I hope this gives you a framework for thinking about your problem-- you need to look up using the persistable store to decide how you want to store your state.
