I made an application which is running in the background. A Predefined mobile number(PDN) is set in that application. This PDN is the phone number of another mobile. When PDN calls to the Mobile where my application is installed, it auto receives the call without any sound, but the display is changed. To prevent this I take a screenshot of the phone and cover the display when it auto answers the call. I take the screenshot perfectly and store in phone memory. But now there is problem.......... How can I display the screenshot image in full screen by the application which is running in the background only at the time of auto answer? Is it possible? Please give me proper suggestion on that. I am waiting for your help.

Thanks in advance,
