Hi.

I use code from example:

http://supportforums.blackberry.com/t5/Java-Development/Create-a-Background-Application/ta-p/445226

but I can't run PopUp class from background class.

Now I use:

UiApplication.getUiApplication().invokeLater( new Runnable() {
    public void run(){
        UiApplication.getUiApplication().requestForeground();

        //Invoke PopUp calss

        UiApplication.getUiApplication().requestBackground();
    }
});

Is this an alternative?

Thanks for the reply.

I try use this this code, but it's not work for my correctly.

Because if a use loop, the Dialog always invoke.

Now i use Timer, and it's work normally (with Popup). 

May by Timer is not the best option?

Sorry I don't realy understand your solution or even the problem that youare are trying to resolve.  Bt if it works, that can't be bad!

Try this:

Application.getApplication().invokeLater(
  new Runnable() {
    public void run() {
      Dialog.alert("The toast is burning");
      }
    }
  );

This is my code:

public void run() 
          {
               while (!stopThread) 
               { 
                    //In this plase I need Invoke PopUp

                    try 
                    { 
                         sleep(5000); 
                    } 
                    catch (Exception e)
                    { 
                         //Exception handling would go here. 
                    } 
               } 
          } 

 if I use next code to run PupUp, Nothing happens.

UiApplication.getUiApplication().invokeLater( new Runnable() {
    public void run(){
        UiApplication.getUiApplication().requestForeground();

        //Invoke PopUp calss

        UiApplication.getUiApplication().requestBackground();
    }
});

 if I use this code

synchronized(Application.getEventLock()){    UiEngine ui = Ui.getUiEngine();
    Screen screen = new Dialog(Dialog.D_OK, "Look out!!!",
        Dialog.OK,           Bitmap.getPredefinedBitmap(Bitmap.EXCLAMATION),         Manager.VERTICAL_SCROLL);
    ui.pushGlobalScreen(screen, 1, UiEngine.GLOBAL_QUEUE);
}

 the Dialog box invoke every 5 seconds.

I need invoke PopUp screen only one times. And get responce from PopUp screen.

you can get the return value using a DialogClosedListener.

save the state in a boolean flag and don't display new screens while one is displayed.

LSphone, I try use your example. PopUp screen is not initialized.
