Handling Key events in background running application !!

[sanjayrajwani]

Hello everyone..

I am trying to handle key event in an application that is running in the background. I send the application in background using this code:

TApaTask task(iEikonEnv->WsSession());
task.SetWgId(CEikonEnv::Static()->RootWin().Identifier());
task.SendToBackground();

I write this code in the AppUi constructor, so that the application starts in the background, not visible to the user. Next, in the in my AppContainer class I override the OfferKeyEventL function to perform some action (e.g. bringing the application back to foreground) on the Call button like this:

TKeyResponse CHelloWorldAppView::OfferKeyEventL(const TKeyEvent& aKeyEvent,enum TEventCode aType)
{
if (aType == EEventKey)
	{
	if (aKeyEvent.iScanCode == EStdKeyYes)
		{
		TApaTask task(iEikonEnv->WsSession());
		task.SetWgId(CEikonEnv::Static()->RootWin().Identifier());
		task.BringToForeground();
		return EKeyWasConsumed;
		}
	}
	return EKeyWasNotConsumed;
}

But the desired action is not taking place. How can I make the background application respond to normal user behavior, like i said to the call button.

Thanks
