I have made a sample code to run the midlet in background by calling the display.seCurrent(null) method in startApp() method.
I am testing this on nokia 2630 classic handset 5th Edition.
When I launch the application the following screen is coming with Quit command and with the following string.
"Nothing to display"
When I press the right softkey to Quit its close the sampleApp (my midlet).
Please suggest me what to do to make the mobile's main screen visible while my sampleApp is running in background.
