How can I refresh my screen or run initial process in background
<p>My main screen has a process which can take 20-30 seconds to load the information on to the screen. While this is happening the screen is just black. I have tried using a ProgressDialog to let the user know the process is running but as the screen is black you cannot see it. Can I refresh the screen so that the dialog is visible or do I need to run my initial process in background so that the screen is visible?</p>
