The other solution for this is that you can just add the file that is being given below in the set-up of the Adobe Air that you have done in the system and then just see that whether it is working out well or not:
Code:
stage.nativeWindow.visible = true;
Make the changes in the settings and then see that the application is working out or not. And still he issue is being caused then I guess that the application might have crashed. The white screen is said to be the displayed for the material when the application crash in the simulator, or nay of the potential change has been made in the settings.
