[nishad.amit1986@gmail.com]

Hello Sir,

I use code to bring application in the background

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

iCoeEnv undeclared(first use this function)

Please help me shourt out the problem

iEikonEnv is a macro, casting iCoeEnv (which is a CCoeEnv variable in a few classes) to CEikonEnv.
You are most likely using this code snippet where there is no iCoeEnv variable. But it is not a problem, just use CEikonEnv::Static() instead, just as it is seen in the second line of the snippet.
So

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